Problems solved by technology

Existing X-ray products are controlled by software, which involves cumbersome conversion of exposure and perspective modes brought about by the rotation of various tubes. It is difficult to maintain and control more intuitively and easily from the outside, and software control itself has Certain risks, prone to misoperation, will cause safety problems for patients
In addition, when the ball tube is in line with the TV image system, the system can only recognize the exposure method of the film box, and cannot perform electronic point film and digital exposure methods, and the function is single

Embodiment 1

[0016] In this embodiment, only one limit switch is used on the rotating shaft of the X-ray machine tube.

[0017] The first limit switch for detecting the rotation angle of a tube is installed on the rotating shaft of the X-ray machine tube, and is connected to the input terminal of the logic circuit, which is partly set in the core control cabinet (CCS) of the X-ray machine , its circuit structure is shown in Figure 1. The first limit switch is used to detect the rotation angle of the X-ray machine tube from 0° to 90°, and the contact signal is sent to the high voltage generator through the logic circuit; When the X-ray machine has a film box or no film box, select one of the states to perform the exposure operation; the logic circuit is used to receive the signals of the first limit switch and the switching switch, and the output terminals are respectively connected with the exposure signal input terminals and the high-voltage generator. The bed state recognition input is c...

Embodiment 2

[0025] This embodiment is the situation where two limit switches are used on the X-ray machine bulb.

[0026] As shown in Figure 2, the difference from Embodiment 1 is that a second limit switch is installed on the rotating shaft of the X-ray machine tube to detect the rotation of the X-ray machine tube from 0° to 180° Angle, the contact signal is sent to the high voltage generator through the logic circuit, that is, the input terminal of the first XOR gate IC1D in the logic circuit is respectively connected with the first limit switch and the first limit switch through the first photocoupler D3 and the second photocoupler D4 The second limit switch, and after passing through the second photocoupler D4, the second limit switch is output to the bed state recognition input terminal of the high voltage generator through the fourth photocoupler D7.

[0027] The specific judgment process includes the following five situations:

[0028] 1) When the first limit switch is closed (tha...

Abstract

The invention relates to a control device for the bulb tube rotation position of an X-ray machine. The device of the invention is provided with a first limit switch used for detecting the rotation angle of 0-90 DEG of the X-ray machine bulb tube; contact signals are sent to a high-voltage generator through a logic circuit; the invention also comprises a shifting switch which selects one state to carry out an exposure operation when the X-ray machine has a magazine or has no magazine; the invention also comprises a logic circuit; the input terminal of the logic circuit is connected with the first limit switch and the shifting switch, while the output terminal thereof is respectively connected with the input terminal of the exposure signal of the high-voltage generator and the input terminal of lathe bed state recognition. The invention automatically controls the shifting of the lathe bed through the rotation of the bulb tube by combing software and hardware, but mainly by hardware mode; the position detection is exact, the action is reliable, and the invention practicably ensures the personal safety of the patients and system safety; furthermore, the invention can implement multi-passage and multi-way clairvoyance, digital exposure and spot film exposure; the doctor is not easy to generate error operations; meanwhile, the risks which are brought by the software is prevented.

Description

technical field [0001] The invention relates to a medical X-ray machine equipment, in particular to a control device for the rotation position of the ball tube of the X-ray machine. Background technique [0002] X-ray products are common human body detection equipment in clinical medicine. Since the tube and beam limiter of X-ray products can rotate from 0 degrees to 180 degrees, when the tube rotates to deviate from the horizontal position, effective exposure and Prohibited control of fluoroscopy, so as to prevent the high-voltage control cabinet from receiving false action signals and causing X-rays to be released by mistake, so as to protect the personal health and safety of patients. Existing X-ray products are controlled by software, which involves cumbersome conversion of exposure and perspective modes brought about by the rotation of various tubes. It is difficult to maintain and control more intuitively and easily from the outside, and software control itself has Ce...
