Description

[Detailed description of the invention] (b) Industrial application field INDUSTRIAL APPLICATION This invention is utilized in the field of a medical diagnostic device.

TECHNICAL FIELD The present invention relates to an X-ray television system for fluoroscopy and photographing of X-ray images, which is used mainly for gastrointestinal traversal in medical diagnostic equipment.

(B) Prior art The configuration of such a system includes an X-ray fluoroscopic imaging table, an X-ray high voltage device, an X-ray tube, an image intensifier, an
Consists of line television camera.

The control vehicle of the X-ray television system has the following eight parts.

■Sweeping panel of X-ray fluoroscopy table (including sweeping switch and display section) ■Operation panel of X-ray high voltage equipment (including sweeping switch and display section) ■For observing X-ray fluoroscopic images This is a foot switch that turns the X-rays on and off during fluoroscopy.

(c) Problems to be Solved by the Invention In this conventional example, the display units (mainly LED displays) of the X-ray high voltage device and the X-ray fluoroscopy table are distributed in eight locations, so the following problems can be solved. Such problems have been pointed out.

- Since it is necessary to observe many dispersed displays and perspective images on a television monitor, the eyes become fatigued due to the movement of the line of sight.

■Since the display section takes up a large amount of space, the size of the pick-up vehicle increases.

■The design of the control console does not look neat.

Furthermore, in recent years, as the functionality of X-ray high-voltage devices and X-ray fluoroscopic imaging tables has become more sophisticated, the amount of display content has increased, so solving the above-mentioned problems has become an even more important issue.

The purpose of the present invention is to reduce eye fatigue and to reduce eye fatigue by concentrating and sharing the display part of the X-ray television system in one place, which has been distributed among eight control vehicles since X-X. An object of the present invention is to provide an X-ray television system that can be downsized and have a simple design.

(d) Means for solving the problem The above purpose is to provide data for display in the X-ray high voltage equipment and for display on the X-ray fluoroscopic imaging table in an X-ray television system for fluoroscopic and photographing of X-ray images. a character display controller for taking in the data, and a switching means for sending either the display data or the fluoroscopic image video signal from the X-ray television camera to the television monitor via the controller. This allows them to be distant relatives.

(e) The function display section is concentrated on the television monitor and is used as a display screen for display data such as characters in the same way as the display screen for fluoroscopic images, and the screen can be switched to any one of the screens as necessary to avoid shifting the line of sight. For this purpose, a character display controller and a switch are provided.

Embodiment A preferred embodiment of the present invention will be described based on the drawings.

The drawing is a configuration block diagram showing one embodiment thereof.

According to the present invention, a portion 23 having a character display controller 17 and a switch 20 is inserted. Then, data for display in the X-ray high-voltage device and data for display in the X-ray fluoroscopy table 19 are taken into the controller 17 .

In the illustrated embodiment, the switch 20 is the foot switch 13
It is linked with. Its operation is as follows.

When the foot switch 13 is stepped on by the operator,
A high voltage 9 is applied to the X-ray tube 1 by the ray controller 11 and the X-ray generator 10 to generate an X-ray flux 2 .

The X-rays passing through the subject 3 and containing fluoroscopic image information are amplified by an image intensifier 4, and
converted into a visible image.

This visible image is sent to the television camera 6 by the optical system 5,
The camera control unit 7 converts the signal into a video signal of a perspective image, which passes through the video signal switch 20 as it is and is displayed on the television monitor 22 for observing the perspective image.

On the other hand, X-ray high-voltage device display data 15 such as imaging conditions and X-ray fluoroscopy table display data 16 are output as a character display video signal 18 by a character display controller 17, and the foot switch 13 is outputted as a character display video signal 18. When the button is not pressed, it is selected by the video signal switch 20 and displayed on the television monitor 22.

In other words, the system's 8 types of display data are normally displayed on the monitor 22.
When the foot switch 13 is pressed, a perspective image will be displayed.

Normally, during fluoroscopy, there is no need to display the area because the user concentrates on observing the fluoroscopic image.

The added character display controller 17 can be easily realized by combining a commercially available CRT control LSI and a character generator memory.

In addition, the data for display in the X-ray high voltage device is as follows:
Shooting tube voltage, shooting tube current, shooting time, shooting tube current time product, fluoroscopy tube voltage, fluoroscopy tube current, fluoroscopy integrated time, selection status of automatic photography condition setting mode, selection status of fluoroscopy brightness self-φ adjustment mode, film Data regarding the selection status of the concentration setting device, the X-ray tube load factor, and the amount of heat accumulated in the X-ray tube are listed.
Display data on the fluoroscopic photographing platform 19 includes data such as the Φ performance status (preparation completion, etc.) of the quick-shot photographing apparatus, the number of film sheets taken, and error messages when an abnormality occurs in the apparatus are displayed for both.

In the illustrated embodiment, the switch 20 is the foot switch 13
Although the switching device 20 is linked to the switching device 20, a configuration example is also adopted in which the switching device 20 can be operated using another switch located near the operator (with or without such interlocking). Ru.

Although the present invention is particularly effectively implemented in an X-ray television system, it is also applicable to other systems involving fluoroscopy, such as cardiovascular systems.

(G) Effects - Since the display is concentrated in one place, there is less movement of the line of sight, which reduces eye fatigue.

■Since the display is shared, the control vehicle can be made smaller and the price can be lowered.

■The number of parts attached to the control console panel is reduced, allowing for a simpler design.

(2) The character display controller section that needs to be added can be easily incorporated because dedicated LSIs are commercially available at low cost.
