Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radiographic apparatus, and more particularly, to a radiographic apparatus capable of capturing an image of a tissue inside a human body in response to radiation emitted from a radiation irradiator.

[0002]

2. Description of the Related Art There is known a radiographic apparatus for photographing internal tissues of a patient using radiation such as X-rays for examining a disease or injury. In such a radiation imaging apparatus, from the viewpoint of power saving and protection of consumables, a standby mode is automatically set when the apparatus is not used for a certain period of time (including a case where no operation is performed). is there.

[0003]

However, the timing at which the standby mode is released becomes a problem. For example, it is troublesome for the operator to perform a specific operation each time to release the standby mode. In addition, even when it is not necessary to release the standby mode, it is wasteful to release the standby mode uniformly.

[0004] The present invention has been made in view of the above-described problems of the related art, and has as its object to provide a radiation imaging apparatus capable of appropriately canceling the standby mode.

[0005]

(1) In a radiation imaging apparatus according to the present invention, an imaging order is input via a network in a radiation imaging apparatus that sets a standby mode in response to a non-use of a predetermined time. According to the control device for canceling the standby mode, for example, when a shooting order is input via the network, it is determined that shooting should be performed immediately, By releasing the standby mode by the control device, it is possible to take a picture quickly.

(2) Further, it is preferable that the release is performed when the control device is connected to a photographing unit, because unnecessary release can be suppressed.

(3) Further, the control device is connected to a plurality of photographing sections, and when the photographing order is input for a specific photographing section, the standby mode is released only for the specific photographing section. This is preferable because unnecessary release can be suppressed.

(4) Further, in the radiation imaging apparatus according to the present invention, the control apparatus and a plurality of imaging units connected thereto are provided in the radiation imaging apparatus for setting the standby mode when the apparatus is not used for a predetermined time. When the standby mode is set, the standby mode of the control device is released before the standby mode of the imaging unit is released in response to the operation of the control device, and the selection of the imaging unit from the control device is performed. For example, the photographing unit can be selected from the control device in which the standby mode has been released, and the photographing preparation operation including the standby mode can be performed. Is preferable because it can be released.

(5) Further, in a radiation imaging apparatus for setting a standby mode in response to not using the apparatus for a predetermined time, a control apparatus and a radiation irradiator connected to the apparatus are provided. When the standby mode is released in response to operation of the radiation irradiator, for example, when the radiation irradiator is operated, it is determined that imaging should be performed immediately. By canceling the standby mode, the photographing can be performed quickly.

(6) Further, in the radiation imaging apparatus which sets the standby mode in response to the non-use of the predetermined time, when the control apparatus and a plurality of imaging units connected thereto are set to the standby mode, When the control device is associated with the radiation irradiating unit and the specific imaging unit, the standby mode is released for the associated specific imaging unit. Is preferable because it can be canceled.

(7) Further, in the radiation imaging apparatus for setting the standby mode in response to the non-use of the predetermined time, when the control apparatus and a plurality of imaging units connected thereto are set to the standby mode, The control device is configured to release the standby mode for all the associated imaging units when the radiation irradiation unit is associated with each imaging unit, so that only the necessary imaging units are set in the standby mode. It is preferable because it can be released.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a network system including a radiation imaging apparatus according to the present embodiment.

In FIG. 1, in a hospital, a server 1 and a control device 2 connected to each other by a network N are:
We are building a part of a network system. The control device 2 controls the first radiation irradiator 3, the first radiographer 4 associated therewith, the second radiation irradiator 5, and the second radiographer 6 associated therewith, respectively. They are connected to each other and constitute a radiation imaging apparatus.

A conversion device for converting a radiation image into digital image data is incorporated in each of the first imaging unit 4 and the second imaging unit 6. However, since such an apparatus is known, it will be described in detail below. Is not described. Note that a conventional radiation film may be arranged in the imaging units 4 and 6 instead of the conversion device.

Next, the operation of this embodiment will be described. Here, in order to save power and extend the life of the display, the radiation imaging apparatus according to the present embodiment automatically sets the standby mode when no operation is performed for a certain period of time. The display of the CRT is stopped. Note that, in the standby mode, the control device 2 transmits the main CP
U (not shown) stops the operation, but the sub CPU (not shown) operates.

Further, for example, the server 1 installed in the office room of the hospital receives the reservation information of the photographing, and this can be transmitted to the control device 2 arranged in the photographing room side at appropriate time. I have.

However, in the radiation imaging apparatus in which the standby mode is set, the server 1 via the network N
When a shooting order is input, the sub CPU responds and cancels the standby mode, so that shooting preparation can be started immediately. However, the control device 2 controls the imaging units 4 and 6
If the camera is not connected to the camera, the photographing cannot be performed immediately even if the standby mode is canceled. Therefore, only when the camera is connected to the photographing units 4 and 6, the standby mode may be cancelled.

The radiographing order inputted from the server 1 includes information for specifying the radiographing unit, such as specifying the radiographing unit 4 in the case of radiographing that can be performed while standing, such as radiographing of the chest. There is. Therefore, in the radiation imaging apparatus in which the standby mode is set, the network N
When such an imaging order is input from the server 1 through the server 1, the sub CPU of the control device 2
, The main CPU reads the designation of the photographing unit included in the photographing order, and can release the standby mode only for the photographed unit 4 (or 6) that has been read.

As a modified example, in a radiation imaging apparatus in which the standby mode is set, when an imaging order is input from the server 1 via the network N, the sub CPU of the control device 2 activates the main CPU. Thereafter, the operator can designate one of the photographing units 4 (or 6) from the control device 2 to release the standby mode. According to the above-described example, the standby mode is continuously performed for the imaging unit that is not used, so that waste can be reduced.

Further, when the first radiation irradiating unit 3 is operated, it is determined that the photographing using the first photographing unit 4 is performed. In such a case, the control unit 2 and the first photographing unit 4 are used. It is desirable to release the standby mode. When the second radiation irradiator 5 is operated, it is determined that imaging using the second imaging unit 6 is performed. In such a case, the control device 2 and the standby mode of the second imaging unit 6 are used. It is desirable to cancel.

Further, the control device 2 controls the irradiation units 3 and 5
And the imaging units 4 and 6 may not always be associated with each other, but in such a case, the control device 2
It is also possible to associate the radiation irradiation unit 3 with the second imaging unit 6 by itself. In such a case, in response to the control device 2 associating the first radiation irradiating unit 3 with the second imaging unit 6, the set standby mode of the second imaging unit 6 is released. You may do it. Further, the control unit 2 responds to the correspondence between the first radiation irradiating unit 3 and the second photographing unit 6 and the correspondence between the second radiation irradiating unit 5 and the first photographing unit 4. Then, the standby mode of all the set devices may be released.
