Description

  The present invention relates to a medical image diagnostic apparatus, and more particularly to a technique for shortening an examination time per person.

  The inspection time per person in the medical image diagnostic apparatus includes the time for photographing the subject (referred to as the photographing time and the scanning time), the explanation time for photographing to the subject, and the image diagnostic apparatus. The time for placing the subject on the bed and then moving to the imaging position, and the time for the subject to get off the bed after completion of imaging are included.

  In medical diagnostic imaging apparatuses such as X-ray CT apparatuses and MRI apparatuses, various high-speed imaging techniques for reducing the imaging time per subject have been researched and developed. Research and development of such high-speed imaging technologies include spiral scanning and multi-detector research and development for X-ray CT equipment, and fast spin echo (Fast SE) and echo planar (EPI) methods for MRI equipment. And high-speed pulse sequences. These shorten the imaging time from the start of imaging of the subject to the end of imaging.

  When obtaining a diagnostic image of a subject in the X-ray CT apparatus, first, the operator places the subject on the top plate at the lowest position of the bed and lays it down, and then an operator for adjusting the height of the top plate Operate and move the top and bottom to adjust. Thereafter, the top plate is moved upward to align the examination site of the subject with the center of rotation of the scanner, and the top plate is moved in the direction of the scanner and the examination site is positioned by the projector. After this positioning is completed, an CT scan start operation is performed by the operator.

  Although research and development of high-speed scanning technology for shortening imaging time in X-ray CT and MRI systems is considered to have been achieved, the time required for the subject to start imaging has not changed. As a technique for controlling the bed height of the medical image diagnostic apparatus, there is Patent Document 1.

  Furthermore, from April 2008, a medical checkup for metabolic syndrome (specific medical checkup) started from the viewpoint of adult disease prevention. Metabolic syndrome diagnosis is performed by taking into account other conditions based on the waist circumference (may be visceral fat mass) determined by men and women. In the method of diagnosing metabolic syndrome based on the waist circumference, it is considered difficult to eliminate the influence of subcutaneous fat and individual differences because visceral fat mass is not measured or observed. Thus, a technique for measuring visceral fat mass from an abdominal tomographic image of an X-ray CT apparatus is disclosed.

  As described above, with the development of high-speed imaging technology in X-ray CT apparatuses and MRI apparatuses, the ratio of time excluding imaging time in the inspection time increases, and improvement thereof is desired.

  In addition, as described above, if an X-ray CT apparatus is used for diagnosis of metabolic syndrome, it is considered that a need for further increasing the operation rate of the X-ray CT apparatus will emerge. In that case, how to shorten the time until the start of photographing becomes a problem.

  The present invention has been made in view of the above, and improves the operating rate of a medical image diagnostic apparatus including a scanner or a gantry such as an X-ray CT apparatus and an MRI apparatus and a patient mounting bed. With the goal.

Note that the supply of power and control signals to each unit provided on the rotating plate 12 and the extraction of data from each unit provided on the rotating plate 12 are slip slips provided between the gantry 1 and the rotating plate 12. This is done via a ring (not shown).

  The bed 3 moves the subject between an imaging preparation position and an imaging position, and includes a vertical movement mechanism and a forward / backward movement mechanism that are not shown. The bed 3 is provided with a bed control device 32, a top plate vertical movement control device 33, and a top plate longitudinal movement control device 34 in order to control their operations.

  The console 4 is a part that controls the control system of the X-ray CT apparatus. As shown in FIG. 1, the appearance of the console 4 is such that a keyboard-like operation input device 42 and a monitor 43 are placed on a disk table. A system control system, an image processing system, and a storage system are placed on the sleeve portion of the disk. The system control system consists of a CPU 41 that controls all the control of the system and performs calculation processing of predetermined data, and a scan planning device 44 for creating a scan plan. It comprises a component device 45 and various image processing devices not shown. The storage system consists of a storage device 46 such as a magnetic disk, an optical disk, or a DVD device. In addition to the X-ray imaging conditions, scan conditions, reconstructed image data, etc. input by the operator, the storage system was distributed from an inspection reservation system described later. An examination schedule indicating the examination order of the examinee, physical information of the examinee included in the examination schedule, software for performing the operation of the present embodiment, and the like are stored.

  In the present embodiment, the console 4 is connected to the hospital information system 5 of the hospital where the X-ray CT apparatus is installed. The hospital information system 5 includes a patient information management system 51 and an examination reservation system 52. The patient information management system 51 is a database of personal information, medical data, test image data, test data, medication data, etc. of patients who have received medical care in the past at the hospital. The personal information of the patient includes physical information such as height and weight in addition to personal identification information such as name, ID number, date of birth, age, and sex. Such personal information is input to the system when the subject visits the hospital as a patient and receives medical treatment. The height and weight of the patient are collected by self-reporting the patient on the medical questionnaire or by actual measurement, and are input to the patient information management system 51. Further, medical data, examination image data, examination data, and medication data are input to the patient information management system every time a patient is treated, and a hospital patient database is created.

  The examination reservation system 52 creates an examination schedule for the day based on the information stored or written in the patient information management system for each system of the medical diagnostic imaging apparatus equipped in the hospital, and the created examination schedule is It is distributed as data to the system. The examination schedule includes the order of patients who undergo the examination on that day in the diagnostic imaging apparatus, and personal identification information and physical information of each patient. The contents of the examination reservation system 52 are sequentially updated as the medical treatment progresses on that day, and the updated data is transmitted to each system each time it is updated.

  Next, the operation of the X-ray CT apparatus according to the present embodiment will be described including the operation of the operator. FIG. 3 is an operation flowchart of the present embodiment. First, hospital work is started on the day of the examination, and the hospital information system 5 and the X-ray CT apparatus are turned on. Then, the examination reservation system 52 accesses the in-hospital patient information management system 51, searches patient data scheduled to perform CT examination on the day from the medical data up to the previous day, and creates an examination schedule (step 101). . Note that the examination schedule is sequentially revised according to the examination result on the day.

  FIG. 4 shows a portion of the examination schedule created by the examination reservation system 52 that is relevant to the present invention. In addition to the data shown in FIG. 4, the examination schedule may include imaging instruction clauses relating to the imaging region, scan range, scan pitch, image reconstruction method, and the like. Since physical information such as the patient's height and weight may not be collected during the examination in the hospital, an example is shown in which an examination schedule is created for some patients with missing height and weight data.

  The created examination schedule data is transferred from the examination reservation system 52 to the console 4 of the X-ray CT apparatus via the in-hospital LAN, and stored in the storage device 46 by the CPU 41 (step 102).

  When the reception and storage of the inspection schedule data is completed, the CT inspection is started. When starting the CT examination, the operator first reads the subject information from the examination schedule from the examination schedule. The first patient data read out is displayed on the monitor 43, and the physical information of the subject, preferably the height data among the read out data, is sent to the arithmetic unit of the CPU 41. Then, when the name of the first patient is displayed on the monitor, the operator calls the name of the patient waiting outside the examination room. The arithmetic unit that has received the height data of the subject reads the formula (1) stored in the storage device 46 in advance, and the top height suitable for the subject to lie on the top of the bed 3 TH is calculated (step 103).

ここに、TH：天板高さ
k ：比例定数
H ：被検者の身長
T ：補正値
である。

Here, TH: Top plate height
k: proportionality constant
H: Subject's height
T: Correction value.

Here, the inventor of the present application investigated a theory regarding the height of the couch suitable for the subject to lie on. As a result, with regard to the height of the chair with the purpose of sitting for a long time, various proposals such as TH = k ₁ · H (cm, where k ₁ is a proportional constant and k ₁ = 0.23), The idea that TH = k ₂ · H-1 (cm, where k ₂ is a proportional constant, k ₂ = 0.25) has been found, but the height of the bed of the medical equipment lying on it is made to be tall. Proposal was not found. To lie down on the couch, it is natural to lie down from the seated position using the elbows, and it is not appropriate to refer to the height of the chair intended for sitting. The inventor assumed the above formula (1), and as a result of exploring the proportionality constant k by experiment, it was considered that the value of k is preferably about 0.25 <k ≦ 0.35. We thought it desirable to apply k = 0.3 to the device.

  T in Equation (1) is a correction value determined by the shape of the top plate and the relationship between the top plate and the top plate support frame that supports the top plate. An example of the correction value T will be described with reference to FIG. A bed of an apparatus in which an imaging system is configured by a gantry and a bed, such as an X-ray CT apparatus, an MRI apparatus, a γ camera apparatus, and a positron CT apparatus, is as shown in FIG. That is, the bed is regulated in the lateral direction by the top plate support frame 35 supported by the base portion, and can move (back and forth) along the top plate support frame. The top plate 31 has a flat shape (see FIGS. 5 (a) and 5 (b)) and a concave shape (see FIG. 5 (c)).

  In FIG. 5 (a), the top plate 31 has a flat shape, and its upper surface is lower than the top plate support frame 35 by h. In this case, T = −h. In FIG. 5B, the top plate 31 has a flat shape, and the upper surface thereof and the upper surface of the top plate support frame 35 are at the same height. In this case, T = 0. Further, FIG. 5 (c) shows that the top plate 31 has a concave shape, in which case the top plate height is the top plate height at which the lowest point of the concave surface is calculated, and the edge portion of the top plate or the top plate support higher than that is calculated. The difference from the upper surface portion of the frame 35 is a correction value, and in this case, T = −h.

  The table height data calculated from the patient's height data by the CPU 41 is immediately sent to the bed control device 32 as instruction data, and the bed control device 32 sends the height of the table top to the table vertical movement control device 33. Command to adjust to the indicated value of CPU41. Receiving this command, the top plate vertical movement control device 33 drives the top plate vertical movement mechanism to move (change) the height of the top plate to a height TH at which the subject can easily ride (step 104).

FIG. 6 shows the movement of the couchtop 31 of the bed 3 when performing CT imaging of the subject with the X-ray CT apparatus of the present embodiment. Before the top plate vertical movement control device 33 is operated, the top plate 31 is in the A position (the top of the top plate) where the examination of the last subject on the previous day is completed, and the top plate height at that time is TH _min. It is. When the couch controller 32 receives the top height data from the CPU 41 and issues a top / bottom movement command to change the top height to TH, the top 31 moves from the position A to the height B position. Move to. The above movement of the top plate 31 from the A position to the B position is performed in such a short time that it is completed before the subject enters the examination room.

  When the examinee arrives (enters) into the examination room (step 105), the operator instructs the examinee to lie on the top plate having a height TH suitable for getting on and off. Lies on the top board in accordance with this instruction (step 106).

  Next, when the operator inputs an examination site from the console 4, the top 31 moves to the imaging preset position (C position in FIG. 6) (step 107). In FIG. 6, this can also be performed by a procedure in which the top plate 31 is vertically raised from the B position to the height of the C position and then moved to the C position in the scanner opening direction.

  When the movement to the imaging preset position in step 107 is completed, the operator inputs a CT scan start command from the console 4. Thereby, CT scan is performed (step 108). If necessary, the operator uses a scan planning device 44 to obtain a scanogram (perspective image by an X-ray CT apparatus) based on the imaging positioning data, and in the scanogram, the scan start position of the CT scan, Enter the scan range or scan end position, slice thickness, scan pitch, etc. The scanogram may be performed for automatic setting / control of X-ray conditions (tube voltage, tube current) of CT scan.

  The CT scan irradiates the X-ray irradiation field set by the collimator 14 from the X-ray tube device 13 while keeping the X-ray tube device 13 and the X-ray detector 15 facing each other. This is done by rotating around 6. When the CT scan is started, the X-rays emitted from the X-ray tube device 13 pass through the imaging region of the subject 6 and enter the X-ray detector 15. X-rays input to a plurality of arrayed X-ray detection elements constituting the X-ray detector 15 are converted into electrical signals, converted into raw data by the data collection device 16, and stored in the storage device 46 via the data transmission device 21. The The transmission X-ray detection operation is performed at predetermined angles during one rotation of the X-ray tube device 13 and the X-ray detector 15.

  When the above CT scan is repeatedly performed with step feed or continuous feed of the top plate 31 and is performed on the set scan range that covers the entire examination region of the subject 6, the CT scan ends. . The data acquired by the above X-ray CT imaging is subjected to image reconstruction processing by the image reconstruction device 45. As a result, the imaging region of the subject is displayed on the monitor 43 as a plurality of tomographic images or three-dimensional images.

  When the CT scan ends, the CPU 41 outputs a command to the bed control device 32 to move the top plate 31 of the bed 3 to the A position where the subject gets down. Then, the bed control device 32 first issues a command to the top plate back-and-forth motion control device 34 to move the top plate 31 back to the photographing preset position (C position), and then the top-plate up-and-down motion control device 33 and the top-plate back-and-forth motion The controller 34 is instructed to move the top 31 to a position (position A) where the subject at the bottom of the top gets down. Thereby, the top plate 31 is moved from the D position of the scan end to the C position by the control of the top plate back-and-forth motion control device 34, and then both the top plate back-and-forth motion control device 34 and the top plate up-and-down motion control device 33 are moved. By control, the subject 6 is moved from the C position to the A position, and the subject 6 gets off the top board 31 (step 109). Then, CT imaging is performed for the next subject in the same procedure.

  According to the first embodiment of the present invention described above, the height of the bed is adjusted almost simultaneously when the operator calls the name of the subject and instructs to enter the examination room. Since the height of the bed has already been adjusted when entering the room, the inspection time can be shortened. In addition, when the subject gets on the top plate, the top plate moves to the preset position for photographing positioning at the shortest distance, and when the photographing is finished, the top plate moves to the bottommost position at the shortest distance, so that the inspection time is shortened.

  Next, a second embodiment of the present invention will be described. The first embodiment can be applied when the patient's personal information (hereinafter referred to as `` PI '') includes height data, but the subject has no height data in the PI, for example, FIG. No. shown in FIG. In the case of the third subject, or when the subject is brought into the examination room by a stretcher. This embodiment is a preferred example in that case.

  FIG. 7 shows a flowchart for obtaining the top plate height suitable for getting on and off the subject in the present embodiment. In this embodiment, first, the operator depends on the correction value T based on the top plate shape of the bed 3 described above, the bed height SH of the stretcher held by the hospital, and the age of the country where the X-ray CT apparatus is installed. The reference position (hereinafter referred to as “Table A”) is stored in the storage device 46 of the X-ray CT apparatus (step 201). For example, in Japan, the standard position of the country where the equipment is installed is described in “Revision of Japanese Nutritional Requirements (Report)” by the Public Health Council report of June 28, 1999 shown in Figure 8. In addition, “Body Criteria by Age Classification” can be used.

  When the storage of step 201 is completed, the CPU 41 then obtains an examination schedule on the day of examination (hereinafter referred to as `` ES '') from the hospital information system (hereinafter referred to as `` HIS ''). The PI including the height, weight, age, and sex is obtained, and the subject is sequentially identified by the operation input device 42 (step 202). The flow does not stop even in cases where the identified subject's PI does not include height, height, or weight among the data of height, weight, age, and sex.

  Next, the CPU 41 checks whether there is information on a stretcher (hereinafter referred to as `` ST '') regarding the movement of the subject to the laboratory in the identified subject PI (step 203). If it is determined that there is ST information, that is, the subject is moved to the examination room by ST, the process proceeds to step 204, and if there is no ST information, the process proceeds to step 205.

  When there is ST information, the CPU 41 outputs a command for adjusting the height of the top 31 of the bed 3 to the bed control device 32 according to the equation (2). Thus, before the subject is transported from the hospital room by the ST, the top 31 is moved to the bed height SH of the ST (step 204).

ここに、SHはSTのベッドの高さである。

Here, SH is the height of the ST bed.

  On the other hand, if there is no ST information, it is determined from the PI whether or not the ST is in a state necessary for transporting the subject to the examination room (step 205). This step 205 makes it possible to cope with the fact that a test schedule is established in which the subject is rescued and transported from outside the hospital when the hospital accepts the patient's lifesaving emergency. In step 205, if it is determined that ST is necessary, the process proceeds to step 204, and the height of the top 31 is adjusted to SH. If it is determined that the ST is not necessary, the process proceeds to step 206.

  In step 206, the CPU 41 determines whether or not PI includes information on the height of the subject (hereinafter referred to as “H information”). When the H information is included in the PI, the CPU 41 sets the height of the top plate when the subject is placed on the top plate 31 to TH = 0. Calculation is performed by 3 × H + T, and the data is sent to the bed control unit 32. Thereby, the top plate height is adjusted.

  If there is no H information, the CPU 41 determines whether or not there is weight information of the subject (hereinafter referred to as “W information”) in the PI (step 207). When the W information is included in the PI, the process proceeds to step 208, and when it is not included, the process proceeds to step 212.

  In step 208, the CPU 41 determines whether or not sex information (hereinafter referred to as “S information”) is included in the PI. If S information is included in the PI, the process proceeds to step 209. If not, the process proceeds to step 210.

  In step 209, the CPU 41 refers to Table A based on the W information and S information of the subject, obtains the reference height of the subject, and sets the value to H. Examples of the calculation method include a method of calculating the height of the subject by proportional calculation using the height corresponding to the weight of two age categories with W between them.

  In step 210, the CPU 41 calculates the reference height of the subject from the W information of the subject and Table A, and sets the value to H. As the calculation method, since there is no S information of the subject, there is a method of calculating the average height of men and women from the W information of the subject and Table A.

  Then, the CPU 41 applies the H obtained in each of step 209 and step 210 to the TH = 0.3 × H + T, and calculates the top plate height when the subject is placed on the top plate 31. The value is sent to the couch controller 32. Accordingly, the height of the top plate is adjusted in each case of Step 209 and Step 210.

  If it is determined in step 207 that the PI information does not include W information, the CPU 41 determines whether the PI includes age information (hereinafter referred to as “A information”) (step 41). 212). If the PI includes A information, the process proceeds to step 213. If not included, the process proceeds to step 216.

  In step 213, the CPU 41 further determines whether or not S information is included in the PI. If S information is included in the PI, the process proceeds to step 214, and if not, the process proceeds to step 215.

  In step 214, the CPU 41 refers to Table A based on the A information and S information of the subject, obtains the reference height of the subject, and sets the value to H.

In step 215, the CPU 41 obtains the reference height of the subject from the A information of the subject and Table A, and sets the value to H.
Then, the CPU 41 applies the H obtained in each of step 214 and step 215 to TH = 0.3 × H + T, and calculates the top plate height when the subject is placed on the top plate 31. The value is sent to the couch controller 32. Accordingly, the height of the top plate is adjusted in each case of step 214 and step 215.

  In step 212, if it is determined that there is no A information in the PI, since there is no H information, W information, or A information of the subject, it is abandoned to estimate the height of the subject, The height of the top plate 31 of the bed 3 is set to the lowest of the specification values of the apparatus (step 216). The CPU 41 sends the lowest value of the top board to the bed control device 32. Thereby, the top plate height is adjusted to the lowest position.

According to this embodiment, even in the case of a subject who does not have the height or / and weight data of the subject, the top plate can be adjusted in advance to a position where the patient can easily ride. Although described, the present invention is not limited to the above embodiment, and can be modified without departing from the gist of the present invention. For example, in the above embodiment, the present invention has been described by taking an X-ray CT apparatus as an example of a medical image diagnostic apparatus, but the present invention can also be applied to an MRI apparatus, a γ camera apparatus, and a positron CT apparatus.

  In the above embodiment, the example in which the height of the top plate is obtained from the equation TH = 0.3 × H + T has been described. However, the proportionality constant of this equation is not limited to 0.3, and is set to an appropriate numerical value. It may be variably set. When the proportionality constant is variably set, the equation (1) is displayed on the monitor 43, and the operation input device 42 is operated to change the proportionality constant.

  Further, in the above embodiment, the correction value T corresponding to the shape of the top plate is added to the equation (1), but this correction value is not so large, so this correction is performed as necessary. You can go.

  In addition, although explanation is omitted in the above embodiment, since the height adjustment of the couch top is automatically performed, if a doctor, a nurse or an attendant is in the examination room, the moving couch top Since there is a possibility of contact, it is good to take measures. For example, before the top plate moves, it is possible to alert the person in the examination room by voice, or to provide a touch sensor on the top plate portion.
