BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an X-ray control apparatus, and in particular, it is used in combination with various X-ray imaging apparatuses, and stores a plurality of anatomical programs for each surgical procedure and selects any of them. To an improved X-ray controller of the type possible.

[0002]

2. Description of the Related Art Conventionally, various X-ray imaging devices such as an indirect imaging device, a Bucky imaging device, or a tomographic imaging device
It may be used in combination with a line control device. In such a case, conventionally, the operator manually presses the anatomical program button on the X-ray control device side to change the setting so that the anatomical program shown by the X-ray imaging apparatus matches, and the X-ray control apparatus is set to the X-ray control apparatus. I am trying to interlock with the radiography equipment.

[0003]

However, in the conventional anatomical program, if the setting on the X-ray control apparatus side is linked to the X-ray imaging apparatus side by manual operation as in the prior art, the operator is burdened and mistaken. There is a problem that it is easy.

In view of the above, the present invention reduces the burden on the operator regarding the setting of the anatomical program, and automatically adjusts it to the setting on the side of the X-ray imaging apparatus so that the X-ray imaging apparatus can confirm the setting. It is an object of the present invention to provide an improved X-ray controller.

[0005]

In order to achieve the above object, the X-ray control apparatus according to the present invention comprises an anatomical program code input / output means, and the input anatomical program code is set to the current setting. Compared with the anatomical program code, if they do not match, the code is reset, and the code of the reset anatomical program is output to the outside through the above-mentioned input / output means. The external X-ray imaging device automatically sets the anatomical program on the X-ray controller side and outputs the set anatomical program code to the outside. The set anatomical program can be confirmed on the device side.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 shows the X according to the present invention.
1 shows an embodiment in which the line control device 40 is combined with an indirect photographing device 50. In FIG.
X-rays are emitted from the ray tube 20. A high voltage is supplied to the X-ray tube 20 from a high voltage generator 30.

The X-ray controller 40 has a microcomputer 41 built therein, an imaging condition setting device 42 for controlling the high voltage generator 30, an X-ray exposure switch 43, an input port 44 and an output port 45. Equipped with.
Although not shown, a plurality of operation buttons are provided, and the operation method can be determined by setting an operation code for each operation button by default.
Then, a plurality of anatomical programs (imaging conditions) are stored in the memory of the microcomputer 41 for each of the surgical operation buttons. This anatomical program is displayed on the display 61 arranged on the panel as shown in FIG. 3, and by pressing the corresponding one of the anatomical program buttons 62 arranged near the display 61, the arbitrary anatomical program can be displayed. You can choose. This anatomical program is obtained and measured by using a human body phantom or the like when installing and adjusting the apparatus, and is stored.

In this case, since it is combined with the indirect photographing device 50, the indirect photographing technique button is pressed,
An anatomical program button 62 having a number corresponding to an appropriate one among the anatomical programs displayed on the display 61 is pressed. Here, by providing a page switching function, it is possible to cope with an increase in the number of anatomical programs without increasing the number of anatomical program buttons 62.

When the X-ray exposure switch 43 is pressed, the test conditions (120 KV, 1 mA,
About 0.3 sec) is set in the imaging condition setting unit 42 by the microcomputer 41, and a high voltage is supplied from the high voltage generator 30 to the X-ray tube 20 based on the condition, and X-rays are emitted. The X-ray exposure switch 43 may be provided on the indirect imaging device 50 side, and in that case,
The exposure signal is transmitted to the X-ray controller 40.

The X-ray transmitted through the subject 10 is a PLI tube (Proximity Liner Image Intensifie) of the indirect photographing device 50.
r Tube) 51, and an X-ray transmission image by visible light is output. The emitted light is captured by the silicon photocell 54, converted into a photocurrent, and integrated by a photocurrent integrator 55. The integrated value is converted into a digital value by the A / D converter 56. This digital value is sent to an APR code calculator 57 that calculates a code of an anatomical program (referred to as an APR code). The APR code (5 bits) thus calculated is sent to the X-ray controller 40 via the output port 58.
A camera 52 is attached to the output surface of the PLI tube 51, and the X-ray film 53 is transported to the camera 52 as needed and set.

When the APR code is sent from the indirect photographing device 50, it is received by the input port 44, and the microcomputer 41 performs the operation as shown in the flow chart of FIG. That is, first, it is determined whether or not there is a change in the APR code loaded into the microcomputer 41 via the input port 44, and when the change occurs, the input APR code is further changed to "00".
000 ”is determined. Otherwise, it is determined whether the input APR code is different from the currently set APR code. Here, if they are different, the current APR code is changed to the input APR code, the shooting condition stored is read out based on this, and sent to the shooting condition setting unit 42 to set the shooting condition. Further, the APR code of the set photographing condition is sent to the indirect photographing device 50 via the output port 45. The indirect photographing device 50 receives this via the input port 59 and confirms that the photographing condition has been changed. After this confirmation, the film 53 is conveyed to the camera 52, and the X-ray controller 40 generates a high voltage from the high voltage generator 30 based on the above-mentioned photographing conditions in response to the exposure signal from the X-ray exposure switch 43. Let As a result, X-ray irradiation is performed from the X-ray tube 20, and indirect photography is performed on the film 53.

In each of the determinations after the APR code is fetched into the microcomputer 41 through the input port 44, if the opposite result is obtained, the process returns to the first step of FIG. The input APR code is different from the current APR code and the input APR code should be changed, but when this is not done by pressing the anatomical program button 62, etc., the input APR code becomes "00000". ing. At this time as well, since the steps are restarted from the first step, "000000" can be said to be a signal for instructing resetting.

In the above, since the APR code is exchanged between the X-ray controller 40 and the indirect photographing device 50 and the number of the anatomical program button 62 is not exchanged, the page switching function can be supported.

In the above description, the case of combination with the indirect imaging apparatus 50 has been described, but it goes without saying that it can be combined with another X-ray imaging apparatus such as a Bucky imaging apparatus. Also, the display number of anatomical program,
The number of anatomical program buttons 62 and the like are not limited to the above example.

[0015]

As described in the above embodiments, according to the X-ray control apparatus of the present invention, the APR code sent from the X-ray imaging apparatus or the like to be combined with the X-ray control apparatus is received and the anatomical program is set accordingly. Is automatically performed and the APR code after the setting is output, so that the state can be confirmed in the X-ray imaging apparatus or the like. Therefore, it is possible to eliminate shooting failures.
