Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to an X-ray fluoroscopic imaging control device, and particularly relates to an X-ray fluoroscopic imaging control device suitable for automatic fluoroscopic control after rapid photography.

[Background of the idea]

Conventional X-ray fluoroscopic photography control equipment, after quick photography,
In particular, the function is fixed, either automatically transitioning to fluoroscopy operation after each shot in the middle of divided shooting, or allowing fluoroscopy to be performed automatically, or it is not possible to perform such automatic fluoroscopy. There was no way to decide whether or not to perform automatic fluoroscopy before taking a snapshot.

Therefore, an apparatus was devised in which automatic fluoroscopy could be selected, but such an apparatus required an automatic fluoroscopy selection switch, which caused the problem of cluttering the operation panel.

[Purpose of invention]

The present invention was developed to solve the above-mentioned problems, and is an X-ray fluoroscopic imaging control that allows automatic fluoroscopy to be selected and determined before taking a quick shot, without complicating the operation panel due to the addition of switches. The purpose is to provide equipment.

[Summary of the idea]

The device of the present invention was developed based on the fact that in the usage of an X-ray fluoroscopic imaging device, if fluoroscopy is performed immediately before rapid photography, fluoroscopy is generally performed after rapid photography. With something that
If fluoroscopy is being performed immediately before a quick shot, that is, when the X-ray image recording medium is in the standby position, it is stored in the memory circuit as fluoroscopy in progress, and after the quick shot, that is, when the X-ray image recording medium is returned to the standby position. At times, if the stored contents of the memory circuit are under fluoroscopy, the X-ray control device is controlled to automatically perform fluoroscopy operation,
This is to achieve the above purpose.

[Example of idea]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a circuit diagram showing an embodiment of the X-ray fluoroscopy control device according to the present invention. In the figure, 1 is a fluoroscopic switch that is turned on when performing fluoroscopy, and 2 is a fluoroscopic switch that is turned on when performing a snapshot photographing. Switch 3 is a standby position sensor that is turned ON when a holder (not shown) containing an X-ray image recording medium such as an X-ray film or an X-ray image storage plate is in a standby position. 4 is a memory circuit that turns on the fluoroscopy flag when the fluoroscopy switch 1 is turned on, indicating that the system is "under fluoroscopy", and turns off the fluoroscopy flag as not being "under fluoroscopy" when the fluoroscopy switch 1 is turned off. be.

A control circuit 5 controls the X-ray control device 6 as follows. First, when the fluoroscopy switch 1 is turned on, a fluoroscopy command (fluoroscopy ON signal) is given to the X-ray control device 6 to cause it to perform a fluoroscopy operation. Further, when the quick-shooting switch 2 is turned on, the X-ray control device 6 is operated for quick-shooting. If the quick-shot switch 2 is turned ON and the fluoroscopy flag is ON in the memory circuit 4 at this time, that is, if fluoroscopy has been performed just before the quick-shot shooting operation, the standby position sensor 3 is turned ON after the quick-shot shooting operation. When this occurs, a fluoroscopy ON signal is output, causing the fluoroscopy operation to be performed immediately. If the quick-shot switch 2 is turned ON and the fluoroscopy flag is OFF in the memory circuit 4, that is, if fluoroscopy has not been performed before the quick-shot shooting operation, the standby position sensor 3 is activated after the quick-shot shooting operation.
When it is turned on, it outputs a fluoroscopy OFF signal and finishes each operation without going through the fluoroscopy operation.

Next, the operation of the above-mentioned device of the present invention will be explained with reference to FIG. First, when you turn on the quick-shoot switch 2,
If it is "under fluoroscopy", the fluoroscopy flag is turned ON in the memory circuit 4, and if it is not "through fluoroscopy", the fluoroscopy flag is turned OFF. On the other hand, the X-ray image recording medium (not shown) moves from the standby position toward the imaging position, and at this time, fluoroscopy is interrupted. When the X-ray image recording medium reaches the imaging position, X-rays are emitted,
After the imaging is completed, the X-ray image recording medium returns to the standby position. As a result, when the standby position sensor 3 turns on,
The control circuit 5 checks the fluoroscopy flag in the memory circuit 4. At this time, if the fluoroscopy flag is ON, a fluoroscopy ON signal is output to the X-ray control device 6 to perform the fluoroscopy operation, and if the fluoroscopy flag is OFF, the
A fluoroscopic OFF signal is output to the line control device 6 to terminate each operation without performing fluoroscopic operation.

In addition, if fluoroscopy was not performed immediately before taking the snapshot,
That is, when X-rays are not being emitted, this fluoroscopic OFF signal means that the X-ray control device maintains that state, so it may be desired to be output.

In addition, the present invention is capable of capturing one image on the entire surface of one X-ray image recording medium if the X-ray image recording medium returns to the standby position every time one image is taken. The present invention can be applied to a variety of devices, such as devices that capture a plurality of images on a single X-ray image recording medium.

[Effect of idea]

As described above, in the present invention, it is not fixed whether or not automatic fluoroscopy can be performed after quick-shot photography, but whether or not automatic fluoroscopy can be performed after quick-shot photography is determined by the selection of whether or not to perform fluoroscopy immediately before quick-shot photography. can be determined. Moreover, its structure does not require the addition of switches as in the past, and has the advantage of not cluttering the operation panel.
