DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray imaging control apparatus and its control method.

[0002]

2. Description of the Related Art Conventionally, when performing image diagnosis in the medical field,
The X-ray photographed film image was hung on a shakasten and observed. However, a normal X-ray film is set to enhance the contrast in a density range of about 1.0 to 1.5 D, which is too easy to observe, in order to facilitate the observation of the diagnostic site. Slightly deviates from the appropriate condition, the image is immediately overexposed or underexposed, which adversely affects the diagnosis based on image interpretation.

On the other hand, with the development of computers in recent years,
Computerization has also become widespread in the medical field. This trend is also rapid in the field of diagnostic imaging, and various CT
There is a remarkable spread in the use of diagnostic equipment using ultrasound, ultrasonic diagnostic equipment, and radioisotopes. Then, a concept called "comprehensive image diagnosis" has emerged in which various diagnostic devices are connected by a computer to comprehensively diagnose various modality images. However, an X-ray film image is essentially an analog image, and although it is most frequently used in image diagnosis and is regarded as important, it does not fit well into comprehensive image diagnosis. It was an obstacle to computerization.

In recent years, however, X using a solid-state imaging device or the like has
X-ray imaging has been developed, and X-ray image digital image reading and imaging using a computer has also started gradually for X-ray images. The use of this X-ray image digital photographing apparatus makes it possible to adjust the contrast of an image that has already been photographed, or to immediately re-take an image if the photographing fails. Therefore, even if the amount of X-rays is too large or too small according to the part to be photographed, it is possible to make corrections after photographing in a certain range.

However, when a digital X-ray imaging apparatus is used, the amount of X-rays received by the subject increases when the amount of X-rays received is large. Needless to say, it is important to take pictures while maintaining sufficient image quality.

Therefore, conventionally, an X-ray digital image acquisition device and an X-ray generation device are combined and an X-ray generation condition optimum for a part to be imaged is sent to the X-ray generation device in advance before the X-ray generation. X that the subject receives by controlling the
A method has been established for minimizing the dose and maintaining an image quality sufficient for diagnosis.

When an X-ray image digital image acquisition apparatus is used, the X-ray imaging conditions (X-ray execution conditions) and the like can be recorded as supplementary information of the image. A method of inputting with the photographing device is required.

Therefore, in the combined X-ray digital imaging control device and X-ray generation device, the X-ray execution conditions are transmitted to the X-ray digital image acquisition device, so that the X-ray generation conditions do not need to be input again. There has been a method of recording the transmitted X-ray execution conditions as it is as supplementary information of the captured image.

[0009]

However, some X-ray generators have only one external imaging condition input unit, such as an X-ray digital image acquisition device, depending on the model. However, there is a problem that it is impossible to connect the X-ray digital image acquisition device.

In addition, when only one external radiographing condition input unit is provided, it is impossible to output the execution conditions to a plurality of X-ray digital image acquisition apparatuses.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and a plurality of X-ray imaging controllers communicate with the X-ray generator even if the X-ray generator has only one external control port. It is a first object of the present invention to make it possible to improve convenience in operation.

It is a second object of the present invention to specify an X-ray generation condition setting without confusion even when a plurality of X-ray imaging control devices are connected.

[0013] When a plurality of X-ray imaging control devices are connected, the X-ray execution conditions obtained after X-ray imaging are as follows:
A third object is to make it possible to transmit an X-ray generation condition used in the X-ray imaging to a designated X-ray imaging control device and to improve operational convenience.

FIG. 2 is a block diagram showing a functional configuration of the X-ray imaging control apparatus according to the first embodiment of the present invention.

As shown in FIG. 2, the X-ray imaging control device 1 is used by being connected to an X-ray generation device 2 and an X-ray generation condition transmission device 3. Note that the X-ray imaging control device 1 can be configured to be connectable to a plurality of X-ray generation condition transmitting devices. However, for simplification of description, one of the X-ray sending condition transmitting devices 3 is used here. Shall be connected to The X-ray imaging control device 1 includes an X-ray generation condition receiving unit 11 that receives an X-ray generation condition transmitted from the X-ray sending condition transmission device 3 and an X-ray that transmits the X-ray generation condition to the X-ray generation device 2 It has an occurrence condition transmission unit 12, a control unit 13, and an operation unit 14. The operation unit 14 includes a photographing condition specifying unit 15 for specifying a photographing condition, and a display unit 16.

The X-ray generation condition receiving unit 11 and the X-ray generation condition transmitting unit 12 correspond to the GEN / IF 117 in FIG. 1, and the control unit 13 includes a CPU 112, an image reading control unit 113, a RAM 115, a ROM 116, a LAN / I

22, the photographing condition specifying unit 15 includes the instruction / specifying unit 12.
1 and the display unit 16 corresponds to the display unit 120.

The operation of the X-ray imaging control device 1 shown in FIG.
The description will be made with reference to the state transition diagram of FIG. 3 and the flowchart showing the setting procedure of the X-ray generation condition of FIG.

First, when the region to be imaged is set by the imaging condition specifying section 15 (YES in step S100), the process proceeds to step S101, and it is determined whether or not X-ray generation conditions have already been set. If it is determined that the setting has not been made (NO in step S101), in step S102, the control unit 13 sends the X-ray generation condition stored corresponding to the setting contents to the X-ray generation unit 12 via the X-ray generation condition transmission unit 12. The designated X-ray generation condition is set by sending the X-ray to the generator 2 (state 1A in FIG. 3). The designation of the X-ray generation condition may be performed any number of times, and after the setting in step S102, the process returns to step S100. When a new designation is made (YES in step S100, YES in step S101), the process proceeds to step S103.

In step S103, it is determined whether or not the X-ray generation condition specified by the external X-ray generation condition transmitting device 3 has already been set. If the X-ray generation condition has been set (YES in step S103), the external X-ray generation condition is determined. After the designation of the imaging condition from the line generation condition transmitting / receiving device 3 is canceled and a warning is given to change to a new occurrence condition specified by the X-ray imaging control device 1 (step S104), the change is made in step S102 (FIG. 3). 3A state).

When the X-ray generation condition specified by the external X-ray generation condition transmitting device 3 is not set (NO in step S103), the set condition is the condition specified by the X-ray imaging control device 1. It is. Therefore, step S10
It is determined whether or not the content specified in step 5 cancels the set condition. If not (NO in step S105), the X-ray generation condition is changed in step S102 (see FIG. 3). 2A state). Conversely, if cancel is specified (YE in step S105)
S), the condition is cleared in step S106, and the state is the same as the condition not set (2C state in FIG. 3).

When an X-ray generation condition is received from the external X-ray generation condition transmitting device 3 (YE in step S107)
S), it is determined whether or not the condition designated by the X-ray imaging control device 1 has already been set (step S108).
If not set (NO in step S108), X
Since the line generation condition is not set or the condition set by the X-ray generation condition transmission device 3, the process proceeds to step S102, and the X-ray generation condition received in step S107 is transmitted to the X-ray generation condition transmission unit 12 via the X-ray generation condition transmission unit 12. By sending it to the X-ray generator 2 (1B or 3B state in FIG. 3). Conversely, if the condition specified by the X-ray imaging control device 1 has been set (YES in step S108), the process returns to step S100 without setting the condition received in step S107 (2B state in FIG. 3). Here, a warning may be displayed to the effect that no condition is set in the X-ray generation condition transmitting device 3.

When the X-ray generation condition is received from the external X-ray generation condition transmitting / receiving device 3 after the setting of the X-ray generation condition, whether the reception is normal or a setting error is made. Can be set by the X-ray imaging control device 1, and can be selected according to the internal implementation of the X-ray generation condition transmitting unit. This is used, for example, in a case where the external X-ray generation condition transmitting / receiving device 3 does not accept a setting error. However, in any case, the received X-ray generation condition is not transferred to the X-ray generation device 2. When the external X-ray generation condition transmitting / receiving device 3 does not transmit the generation condition, the display unit 16 lights a colored warning lamp to indicate that the external signal is not received. Further, when an X-ray generation condition is received from the external X-ray generation condition transmitting / receiving device 3, for example, the lamp is repeatedly turned on and off to indicate to the operator that the setting has not been transmitted to the X-ray generation device.

In the above description, the case where the priority of the X-ray imaging control device 1 directly connected to the X-ray generation device 2 is set higher than the priority of the external X-ray generation condition transmitting / receiving device 3 However, the present invention is not limited to this, and the order of priority can be reversed.

As described above, according to the first embodiment of the present invention, the user designates the X-ray generation condition to the X-ray generation device by the first X-ray imaging control device and waits until the designation is released. Between,
Even if the X-ray generation condition is designated from the second X-ray imaging control device to the X-ray generation device via the first X-ray imaging control device, the first
Does not transfer the condition to the X-ray generator, but if the designation by the first X-ray imaging controller is released, the transfer is performed. Therefore, even if the X-ray generation device has only one external control port, a plurality of X-ray imaging control devices can communicate with the X-ray generation device, and operational convenience can be improved.

Furthermore, even if the second X-ray imaging control device specifies the imaging conditions to the X-ray generator via the first X-ray imaging control device, the first X-ray imaging control device subsequently specifies the X-ray imaging condition. When the X-ray generation condition is specified for the generator, the X-ray generation condition specified by the first X-ray imaging controller is transferred to the X-ray generator. As described above, when a plurality of X-ray imaging control devices are connected, the imaging is performed mainly with the imaging device directly connected to the X-ray generation device. Therefore, it is necessary to specify the X-ray generation condition setting without confusion. Becomes possible.

<Second Embodiment> Next, a second embodiment of the present invention will be described.

FIG. 4 shows a functional configuration diagram of an X-ray imaging control device used in the second embodiment. The difference from FIG. 2 described in the first embodiment is that the X-ray generation condition transmission / reception unit 5 is connected instead of the X-ray generation condition transmission device 3, and accordingly, the X-ray generation device 4 X-ray execution condition receiving unit 23 for receiving X-ray imaging execution conditions (X-ray execution conditions) from the computer, and X-ray execution conditions for transmitting the received X-ray execution conditions to the X-ray generation condition transmitting / receiving unit 5 This is the point that the transmission unit 22 is further provided.

Therefore, in the configuration shown in FIG.
The X-ray imaging execution conditions actually used for the exposure are input from the X-ray generator via the GEN / IF 17 and the received X-rays are received.
The line execution condition is also transmitted to the X-ray generation condition transmitting / receiving device 5 via the GEN / IF 117.

Next, the operation of the X-ray imaging control device 1 shown in FIG. 5 will be described. The procedure for setting the X-ray generation conditions is the same as that described with reference to FIGS. 3 and 4 in the first embodiment, and a description thereof will not be repeated. Therefore, the procedure for storing the X-ray execution conditions after imaging has been performed based on the set X-ray generation conditions will be described with reference to FIG. 6 and FIG.
The description will be made with reference to a flowchart showing the procedure for storing the line execution conditions.

When the imaging is completed, the X-ray execution condition is transmitted from the X-ray generator 4 to the X-ray imaging control device 21 and received by the X-ray execution condition receiving unit 23. If the setting of the X-ray generation condition by the designation of the X-ray imaging control device 21 has been performed (YES in step S201), the received execution condition is recorded in the X-ray imaging control device 21 (step S2).
02) At the same time, the state shifts to the condition unset state (step S)
204, 2D state in FIG. 1). It is not transmitted to the external X-ray generation condition transmitting / receiving device 5.

When the radiographing is performed in a state where the radiographing condition is specified by the external X-ray generation condition transmitting / receiving device 5 (NO in step S201), the received execution condition is
The condition is transferred to the external X-ray generation condition transmitting / receiving device 5 (step S203), and at the same time, the state shifts to the condition unset state (step S204, 3D state in FIG. 3). The X-ray imaging control device 21 does not record the execution conditions.

With the above operation procedure, the external X
When the X-ray generation condition transmitting / receiving device 5 sets the imaging conditions, the X-ray generation condition transmitting / receiving device 5 performs the imaging even if the imaging is actually performed according to the instruction of the imaging condition from the X-ray imaging control device 21. It does not pose any particular obstacle because it recognizes that the state that has not been performed continues.

When the X-ray imaging is completed, an end instruction is input by the operator from the operation unit 14, but at this time, the internal state returns to the condition unset state. Therefore, when the X-ray imaging is completed, the external X-ray generation condition transmitting / receiving device 5 can substantially transfer the imaging conditions to the X-ray generation device 4 again.

As described above, according to the second embodiment of the present invention, when the first X-ray imaging control device designates the imaging condition to the X-ray generator and the imaging is performed following the designation, the X-ray The X-ray execution conditions from the generator are not sent to the second X-ray imaging controller, but are received by the first X-ray imaging controller. on the other hand,
When the imaging conditions are designated from the second X-ray imaging control device to the X-ray generation device via the first X-ray imaging control device, and the imaging is performed subsequent to the designation, the first X-ray imaging control device side The received X-ray execution conditions are sent to the second X-ray imaging control device. As described above, when a plurality of X-ray imaging control devices are connected, the X-ray execution conditions obtained after the X-ray imaging are changed to the X-ray imaging control specifying the X-ray generation conditions used in the X-ray imaging. Since it can be received by the device, it can be used for recording X-ray execution conditions, etc., and the operational convenience can be improved.

Further, even if the second X-ray imaging control apparatus specifies imaging conditions to the X-ray generation device via the first X-ray imaging control apparatus, thereafter, the first X-ray imaging control apparatus performs X-ray imaging. If the X-ray generation condition is specified in the X-ray generation device, and the imaging is performed subsequent to the designation, the imaging execution condition from the X-ray generation device is not reflected on the second X-ray imaging control device, Received by the X-ray imaging control device. Therefore, by performing imaging using the X-ray imaging control device directly connected to the X-ray generation device as a main component, it is possible to return to the X-ray imaging control device that requires X-ray execution conditions, and furthermore, confusion is caused. No shooting can be achieved.

<Third Embodiment> FIG.
This is an example in which a plurality of external X-ray generation condition transmitting / receiving devices 5 are connected to the radiographic control device. In this case, the system determines whether the X-ray generation condition finally used for the X-ray imaging is based on an instruction from the X-ray imaging control device 31 or which X-ray generation condition receiving unit (11a to 11n) has been obtained. It is stored internally. Then, when the X-ray imaging is performed and the X-ray execution condition is received, based on the information stored in the system, the apparatus that specifies the X-ray generation condition used for the imaging is
The received X-ray execution condition is transmitted.
