Description

  The present invention relates to a radiographic apparatus that obtains a radiographic image of a subject by irradiating radiation, and particularly relates to a radiographic apparatus in which a radiation source and a radiation detector are supported by a C-arm.

  There are various configurations of X-ray imaging apparatuses that irradiate a subject with X-rays and image transmitted X-rays transmitted through the subject. For example, there is a configuration in which an X-ray source for irradiating X-rays and an X-ray detector for detecting X-rays are supported on both ends of a C-type support member (C-type arm). Such an X-ray detector having a C-shaped arm is easy to inject a contrast medium into a subject while taking an X-ray fluoroscopic image, and is used, for example, for an angiographic examination of the subject.

  First, the configuration of the conventional X-ray imaging apparatus 51 will be described. As shown in FIG. 9, a conventional X-ray imaging apparatus 51 includes a top plate 52 on which a subject M is placed, an X-ray tube 53 that irradiates the subject M with X-rays, and a detector that detects X-rays. 54, an X-ray tube control unit 56 that controls the tube power of the X-ray tube 53, a C-type arm 57 that supports the X-ray tube 53 and the detector 54, and a C-type arm drive mechanism 59 that drives the C-type arm 57 And a C-type arm drive control unit 60 for controlling the C-type arm drive mechanism 59. In addition, the X-ray imaging apparatus 51 mainly performs various controls in the console 61 that receives various instructions from the operator, a display unit 62 that displays an X-ray fluoroscopic image, and the X-ray imaging apparatus 51. And a control unit 63. Note that the C-shaped arm 57 is supported by a support column 58 (see, for example, Patent Document 1).

  The conventional X-ray imaging apparatus 51 is configured to be able to change the position of the C-type arm 57 with a high degree of freedom according to the region of interest in the subject M. Specifically, the C-type arm 57 can be translated in two directions along the body axis direction A of the subject M and the body-side direction S of the subject M by the C-type arm drive mechanism 59. .

At the same time, the posture of the C-type arm 57 is changed by rotating the C-type arm 57. That is, the C-arm 57 can be rotated in the B direction by changing the distance between the X-ray tube 53 and the fulcrum at which the column 58 supports the C-arm 57. Independent of this rotational movement, the C-arm 57 itself can also be rotationally moved in the direction F that causes the top plate 52 to tilt. As described above, the conventional X-ray imaging apparatus 51 can change the position of the C-type arm 57 in two directions independent from each other, and rotate and move the C-type arm 57 around two independent axes. Thus, the posture of the C-arm can be changed.

However, the conventional example having such a configuration has the following problems.
That is, according to the conventional configuration, an operator's operation mistake is reflected in the drive of the C-arm as it is. When the operator wants to change the position / posture of the C-shaped arm, after selecting whether to move or rotate through the console 61, the operator, for example, how much to move in which direction if moving. It is necessary to make a complicated designation for the X-ray imaging apparatus. As described above, the degree of freedom of movement of the C-shaped arm is improved, but an operator's operation mistake is easily induced. The conventional console 61 is provided with a joystick and an execution button, and the operator operates the joystick while pressing the execution button. Then, the C-arm is driven according to the input driving instruction regardless of whether the operator has made an operation error. That is, the operator notices his / her own operation mistake when the C-arm is actually driven.

  Since there is such a fear, the operator first drives the C-shaped arm as a test to confirm whether the C-shaped arm is driven in the direction intended by the operator. In order to provide an X-ray imaging apparatus that is safer and easier to inspect, a configuration that does not require such trial driving is desired.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a radiation imaging apparatus capable of confirming the presence or absence of an operation error before the support member (C-type arm) is driven. .

In order to achieve such an object, the present invention has the following configuration.
That is, the radiation imaging apparatus according to the present invention includes a radiation source that irradiates a radiation beam, a radiation detection unit that detects the radiation beam, a support member that supports the radiation source and the radiation detection unit, and a movement of the support member. A movement control means for controlling, a movement instruction input means for instructing movement of the support member, a notification means for virtually notifying the operator of movement of the support member based on the movement instruction, and an instruction to execute movement of the support member The movement control means moves the support member based on the movement instruction when the execution instruction is acquired.

  [Operation / Effect] According to the configuration of the present invention, the operator does not move the C-arm by mistake. In order to realize this effect, the radiographic apparatus according to the present invention includes a movement instruction input unit that inputs a movement instruction indicating a movement mode of the support member, and an execution instruction input that acquires an execution instruction of the movement of the support member. Means and a notification means for virtually notifying the operator of the movement of the support member based on the movement instruction. Since the notification means notifies the operator of the contents of the movement instruction when the movement instruction is acquired, the movement instruction input by the operator is directly reflected in the change of the position of the support member. There is nothing to do. Then, upon receiving this notification, the operator can confirm whether or not the operator has made an operation error. That is, the operator can confirm the mode of movement of the support member input by the operator before the support member is actually driven. Thereby, according to the structure of this invention, it is not necessary for the operator to test drive a support member. Therefore, it is possible to provide a radiation imaging apparatus that is safer and easier to operate than the conventional configuration.

  According to a second aspect of the present invention, in the radiographic apparatus according to the first aspect, the movement instruction includes a parallel movement instruction, and the support member moves in parallel based on the control of the movement control means. It is characterized by that.

  [Operation / Effect] According to the above configuration, the operator does not translate the C-arm by mistake. The radiation imaging apparatus according to the above-described configuration includes a movement instruction input unit that inputs a parallel movement instruction indicating a parallel movement pattern of the support member. Since the notification means virtually notifies the operator of the contents of the parallel movement instruction when the parallel movement instruction is input to the movement instruction input means, the parallel movement instruction input by the operator is This is not reflected in the change of the position of the support member as it is. Then, upon receiving this notification, the operator can confirm whether or not the operator has made an operation error. That is, the operator can confirm the manner of translation of the support member input by the operator before the support member is actually translated.

  According to a third aspect of the present invention, in the radiographic apparatus according to the first or second aspect, the movement instruction includes a rotational movement instruction, and the support member controls the movement control means. It is characterized in that it is rotationally moved based on it.

  [Operation / Effect] According to the above configuration, the operator does not accidentally rotate the C-arm. The radiation imaging apparatus according to the above configuration includes a movement instruction input means for inputting a movement instruction indicating a mode of rotational movement of the support member. The notification means virtually notifies the operator of the contents of the rotational movement instruction when the rotational movement instruction is input to the movement instruction input hand. Therefore, the rotational movement instruction input by the operator is provided. Is not directly reflected in the change of the position of the support member. Then, upon receiving this notification, the operator can confirm whether or not the operator has made an operation error. That is, the operator can confirm the mode of rotational movement of the support member input by the operator before the support member is actually rotated.

  According to the configuration of the present invention, it is possible to prevent an operation error in driving the support member by the operator. That is, before the support member is driven, it can be confirmed whether there is an operation error. This is because the contents are sequentially notified to the operator when the operator inputs support for movement. Thus, according to the present invention, it is not necessary for the operator to test drive the support member. Therefore, it is possible to provide a radiation imaging apparatus that is safer and easier to operate than the conventional configuration.

  Embodiments of the radiation imaging apparatus according to the present invention will be described below with reference to the drawings. In the first embodiment, an X-ray imaging apparatus using X-rays will be described.

  First, the configuration of the X-ray imaging apparatus according to the first embodiment will be described.

As shown in FIG. 1, the X-ray imaging apparatus 1 according to the first embodiment includes a top plate 2 on which a subject M is placed and an X-ray tube that irradiates an X-ray beam provided below the top plate 2. 3 and a flat panel detector (FPD) 4 that is provided above the top 2 and detects X-rays transmitted through the subject M. The X-ray imaging apparatus 1 according to the first embodiment includes an X-ray tube control unit 6 that controls the tube voltage, tube current, and X-ray beam pulse width of the X-ray tube 3. Note that each of the X-ray tube and the FPD corresponds to each of a radiation source and radiation detection means.

  The X-ray tube 3 and the FPD 4 are collectively supported by a C-type arm 7. This arc-shaped C-shaped arm has two tips, and is provided with an X-ray tube 3 at one end and an FPD 4 at the other end.

You can also. The C-arm rotational movement control unit corresponds to the movement control means of the present invention.

  Further, the C-arm rotation moving mechanism 11 can also rotate the C-arm 7 around the center of curvature of the C-arm 7. That is, by changing the distance between the fulcrum at which the support column 8 supports the C-arm 7 and the X-ray tube 3, the C-arm 7 can be rotated in the direction indicated by the arrow B in FIG. As indicated by an arrow B, the X-ray tube 3 can be rotated in a direction away from the fulcrum, or conversely, the X-ray tube 3 can be rotated in a direction closer to the fulcrum.

  As described above, the C-arm 7 can be translated in the body axis direction A of the subject M and the body side direction S of the subject M which are orthogonal to each other. The C-arm 7 can be rotated about the body axis direction A of the subject M as a central axis, and can also rotate about the center of curvature of the C-arm 7 independent of this rotational movement and direction. It is possible. As described above, the X-ray imaging apparatus according to the first embodiment is configured such that the position / posture of the C-arm 7 can be freely changed according to the region of interest of the subject M.

  By the way, the top plate 2 is vertically movable, and the X-ray imaging apparatus 1 includes a top plate drive mechanism 13 that drives the top plate 2 and a top plate drive control unit 14 that controls the top plate drive mechanism 13. ing. Thereby, the relative position in the vertical direction between the subject M and the C-type arm 7 can be changed. Further, the X-ray imaging apparatus 1 includes an image processing unit 15 that converts a signal output from the FPD 4 into an X-ray fluoroscopic image or a moving image, and an operation console 22 that acquires an operator's operation. The operator can change the position / posture of the C-arm 7 through the console 22.

  The X-ray imaging apparatus 1 also includes a main control unit 24 that comprehensively controls the control units 6, 10, and 12. The main control unit 24 is constituted by a CPU, and realizes the control units 6, 10, and 12 by executing various programs. Each of the above-described controls may be executed by being divided into control devices in charge of them. In addition, the X-ray imaging apparatus 1 according to the first embodiment includes a display unit 23 that displays an X-ray fluoroscopic image of the subject M. Furthermore, the X-ray imaging apparatus 1 includes a data storage unit 20 and an instruction display unit 21, which will be described in detail later. The instruction display unit corresponds to the notification unit of the present invention.

  The console 22 will be described. FIG. 2 is a perspective view illustrating the configuration of the console according to the first embodiment. As shown in FIG. 2, the console 22 according to the first embodiment includes a joystick 30 and a cancel button 35. The operator can freely tilt the joystick 30 with respect to the four directions of up, down, left and right. That is, the joystick 30 can be tilted in two directions independent from each other.

  According to the configuration of the first embodiment, the C-arm 7 is driven in accordance with an operator instruction through the joystick 30. The joystick 30 is provided with a selection button 31 for selecting whether the C-arm 7 is to be translated or rotated. In addition, the joystick 30 is accompanied by an execution button 32 for executing the parallel movement / rotation movement designated by the operator. The joystick corresponds to the movement instruction input means of the present invention. The execution button corresponds to the execution command input means of the present invention. In addition to the joystick 30, the console 22 has a cancel button 35 for canceling the operator's instruction. This function will be described later.

  Next, an operation when performing an inspection with the X-ray imaging apparatus 1 according to the first embodiment will be described. FIG. 3 is a flowchart for explaining the operation of the radiation imaging apparatus according to the first embodiment. As shown in FIG. 3, in the examination related to the radiographic apparatus according to the first embodiment, the subject placement step S1 for placing the subject M on the top 2 and the parallel acquisition instruction by the operator. The movement instruction acquisition step S2, the rotation movement instruction acquisition step S3 for acquiring the rotation movement instruction by the operator, the drive reservation step S4 for reserving the driving of the C-arm 7, and the execution instruction designated by the operator An execution instruction acquisition step S5 to be acquired, a parallel movement step S6 for moving the C-shaped arm 7 in parallel, a rotational movement step S7 for rotating the C-shaped arm 7 and an exposure step S8 for exposing X-rays are provided. ing. Hereinafter, the details of each step will be described in order.

<Subject Placement Step S1, and Parallel Movement Instruction Acquisition Step S2>
First, the subject M is laid on the top 2. At this time, the operator can instruct the X-ray imaging apparatus 1 to translate the C-arm 7 in the body axis direction A and the body side direction S of the subject M. This instruction is given through the console 22. The selection button 31 attached to the joystick 30 is a button for selecting whether the operator gives an instruction for parallel movement of the C-arm 7 or a rotation movement instruction. In the parallel movement instruction acquisition step S <b> 2, since the operator is going to translate the C-type arm 7, the selection button 31 is pressed, and the operator's instruction is related to the parallel movement of the C-type arm 7. It is determined that

  The operator instructs the parallel movement of the C-arm 7 through the joystick 30. That is, the vertical direction UD (see FIG. 2) of the joystick 30 is assigned to the parallel movement in the body axis direction A of the subject M, and tilting the joystick 30 in the upward direction U causes the C-arm 7 to be moved. An instruction for parallel movement in the direction toward the center of the top 2 along the body axis direction A of the sample M is shown. Conversely, inclining the joystick 30 in the downward direction D indicates an instruction to translate the C-arm 7 in the direction away from the center of the top 2 in the body axis direction A of the subject M. On the other hand, the left-right direction LR (see FIG. 2) of the joystick 30 is assigned a parallel movement in the body-side direction S of the subject M, and inclining the joystick 30 in the right direction R causes the C-arm 7 to move to the top plate. 2 shows an instruction to translate in a direction toward the right side 2 (the back side in the drawing of FIG. 1). Conversely, inclining the joystick 30 in the left direction L indicates an instruction to translate the C-arm 7 in a direction toward the left side of the top plate 2 (front side in the drawing of FIG. 1). However, at this time, the console 22 only accepts an operator's instruction, and the C-arm 7 is not actually driven.

  A parallel movement instruction according to the first embodiment will be described. The parallel movement instruction in the present invention represents a parallel movement pattern of the C-arm 7 input by the operator to the X-ray imaging apparatus 1 through the joystick 30. That is, the direction of the parallel movement is determined by the parallel movement mode in the body axis direction A in which direction the C-arm 7 is translated in which direction the body axis direction A of the subject M, and the subject M. The direction of translation of the body-side direction S, which is how much the body-side direction S is translated in which direction, is shown. This parallel movement instruction is converted by the console 22 into parallel movement data indicating the parallel movement instruction. This parallel movement data is sent to the data storage unit 20 where it is stored.

  Next, the configuration of the instruction display unit 21 will be described. The instruction display unit 21 is composed of a monitor independent of the display unit 23. FIG. 4 is a plan view illustrating the instruction display unit according to the first embodiment. As shown in FIG. 4, a schematic diagram 41 in which the C-arm 7 is viewed from the body side direction S of the subject M is displayed on the instruction display unit 21. The instruction display unit 21 also displays a schematic diagram 42 in which the C-arm 7 is viewed from the body axis direction A of the subject M. The schematic diagrams 41 and 42 show the position / posture of the C-arm 7.

  The schematic diagram 41 includes an icon 412 indicating the top board 2 and an icon 417 indicating the C-arm 7. Similarly to the schematic diagram 41, the schematic diagram 42 also includes an icon 422 indicating the top plate 2 and an icon 427 indicating the C-arm 7. When the operator inputs a parallel movement instruction using the console 22, the parallel movement instruction is sequentially reflected on the display of the instruction display unit 21, and the schematic diagram 41 is changed as shown in FIG. The relative positional relationship between the arm 7 and the top 2 along the body axis direction A of the subject M is displayed. At the same time, the schematic diagram 42 is also changed. That is, when the operator inputs a parallel movement instruction, the parallel movement instruction is sequentially reflected on the display of the instruction display unit 21, and as shown in FIG. 6, as shown in FIG. A relative positional relationship along the body side direction S of the sample M is displayed.

<Rotational Movement Instruction Acquisition Step S3>
Further, the operator can give an instruction to rotate the C-arm 7 through the console 22 around the body axis direction A of the subject M and the center of curvature of the C-arm 7. In the parallel movement instruction acquisition step S <b> 2, since the operator is going to rotate the C-arm 7, the selection button 31 is released, and the operator's instruction is related to the rotational movement of the C-arm 7. Is determined to be.

  An instruction for the rotational movement of the C-arm 7 by the operator is made through the joystick 30. That is, the up-down direction UD (see FIG. 2) of the joystick 30 is assigned rotational movement around the center of curvature of the C-type arm 7, and tilting the joystick 30 in the upward direction U means that the C-type arm 7 Is an instruction to rotate the X-ray tube 3 in a direction approaching the top plate 2. Conversely, inclining the joystick 30 in the downward direction D indicates an instruction to rotate the C-arm 7 in a direction in which the FPD 4 approaches the top plate 2. On the other hand, the left-right direction LR (see FIG. 2) of the joystick 30 is assigned a rotational movement with the body axis direction A of the subject M as the center axis, and tilting the joystick 30 in the right direction R is a C type. An instruction to rotate and move the arm 7 in a direction in which the X-ray tube 3 moves toward the right end of the top plate 2 is shown. Conversely, inclining the joystick 30 in the left direction L indicates an instruction to rotate the X-ray tube 3 in a direction toward the left end of the top plate 2. However, at this time, the console 22 only accepts an operator's instruction, and the C-arm 7 is not actually driven.

  An instruction for rotational movement according to the first embodiment will be described. The instruction for rotational movement in the present invention represents the manner of rotational movement of the C-arm 7 input by the operator to the X-ray imaging apparatus 1 through the joystick 30. That is, the rotational movement instruction is the rotational movement mode in the body axis direction A, which is how much the C-arm 7 is rotated in which direction with the body axis direction A of the subject M as the central axis, and The figure shows how the rotational movement about the center of curvature of the C-type arm 7 is performed, in which direction and how much the center of curvature of the C-type arm 7 is rotated. This rotational movement instruction is converted into rotational movement data by the console 22. This rotational movement data is sent to the data storage unit 20 where it is stored.

  The movement instruction in the present invention is a concept including the above-described parallel movement instruction and rotational movement instruction.

  When the operator inputs a rotational movement instruction, the rotational movement instruction is sequentially reflected on the display of the instruction display unit 21, and as shown in FIG. 7, the schematic diagram 41 is changed, and the curvature of the C-arm 7 is changed. The direction and degree of inclination of the C-arm 7 centered on the center is displayed. At the same time, the schematic diagram 42 is also changed. That is, when the operator inputs a rotational movement instruction, the rotational movement instruction is sequentially reflected on the display of the instruction display unit 21, and as shown in FIG. 8, the body axis of the subject M of the C-arm 7. The direction and degree of inclination with the direction A as the rotational movement axis are displayed.

  Here, the operator can press the cancel button 35. That is, for example, when the operator erroneously inputs instructions for rotational movement and parallel movement, and the schematic diagrams 41 and 42 display driving of the C-arm 7 different from the intention of the operator on the instruction display unit 21, The operator can press the cancel button 35 to cancel the designation of each step. According to the configuration of the first embodiment, this is also reflected in the display of the instruction display unit 21, and the schematic diagrams 41 and 42 return to the initial state.

<Driving reservation step S4>
When the operator finishes inputting the parallel movement instruction and the rotational movement instruction, the parallel movement / posture change of the C-arm 7 is reserved. That is, each instruction given by the operator through the joystick 30 is stored in the data storage unit 20 as parallel movement data and rotational movement data, and the driving mode of the C-arm 7 indicated by these is reserved.

<Execution Command Acquisition Step S5, Parallel Movement Step S6, and Rotation Movement Step S7>
Here, when the operator presses the execution button 32 attached to the joystick 30, an execution command for executing the position / posture of the C-arm 7 is input to the execution button 32. The console 22 sends an execution command signal to the main control unit 24 in accordance with this execution command. When the main control unit 24 receives the execution command signal, it reads out the parallel movement data and the rotational movement data from the data storage unit 20. These are sent to each of the column parallel movement control unit 10 and the C-arm rotational movement control unit 12. In the subsequent translation step S6, the C-arm 7 is actually translated. Specifically, the column parallel movement control unit 10 controls the column parallel movement mechanism 9 to change the position of the C-arm 7. Further, in the rotational movement step S7, the C-arm 7 is actually rotationally moved. Specifically, the C-type arm rotation movement control unit 12 controls the C-type arm rotation movement mechanism 11 to rotate and move the C-type arm.

<Exposure step S8>
When the operator gives an instruction for X-ray exposure, the X-ray tube control unit 6 controls to supply power to the X-ray tube 3 and the X-ray beam is irradiated toward the subject M. . The X-ray beam is in a pulse shape. In this way, an X-ray fluoroscopic image of the subject M is reflected in the FPD 4. Finally, the obtained X-ray fluoroscopic image or moving image is displayed on the display unit 23, and the examination ends.

  As described above, according to the configuration of the first embodiment, the operator does not accidentally translate the C-arm. In order to realize this effect, the X-ray imaging apparatus 1 according to the first embodiment includes a joystick 30 that inputs a parallel movement instruction indicating a parallel movement mode of the C-type arm 7 and a parallel movement of the C-type arm 7. An execution button 32 for inputting an execution command and an instruction display unit 21 for displaying a parallel movement instruction are provided. Since the instruction display unit 21 displays the contents of the parallel movement instruction to the operator when the parallel movement instruction is acquired, the parallel movement instruction input by the operator is directly C-shaped. This is not reflected in the change in the position of the arm 7. Then, the operator can confirm that the setting of the parallel movement mode by the joystick 30 has been input as intended by the operator by receiving this display. That is, the operator can confirm the presence or absence of an operation mistake before the C-arm 7 is translated.

  Further, according to the configuration of the first embodiment, the operator does not rotate the C-arm 7 by mistake. The X-ray imaging apparatus 1 according to the configuration of the first embodiment includes a joystick 30 that acquires a rotational movement instruction indicating a rotational movement mode of the C-arm 7. The instruction display unit 21 displays the contents of the rotational movement instruction to the operator at the time when the rotational movement instruction is input to the joystick 30. Therefore, the rotational movement instruction input by the operator is This is not reflected in the change of the position of the C-arm 7 as it is. Then, the operator can confirm that the setting of the mode of rotational movement by the joystick 30 has been input as intended by the operator by receiving this display. That is, the operator can confirm the presence or absence of an operation error before the C-arm 7 is rotationally moved.

  Thus, according to the configuration of the first embodiment, it is not necessary for the operator to drive the C-arm 7 on a trial basis. Therefore, it is possible to provide the X-ray imaging apparatus 1 that is safer and easier to operate than the conventional configuration.

  The present invention is not limited to the configuration of the above embodiment, and can be modified as follows.
