Problems solved by technology

Because moving parts such as X-ray generators and / or X-ray detectors have multiple degrees of freedom of movement, sometimes due to personnel not paying attention to their movement or the moving parts are misoperated, etc., causing the moving parts to contact patients and medical staff or other obstacles, which may cause injury to personnel on the one hand, and damage to moving parts or obstacles of X-ray imaging equipment on the other hand

Embodiment Construction

[0029] Considering that in the traditional anti-collision scheme, it is necessary to bypass the X-ray path between the X-ray generator and the X-ray detector to avoid blocking the X-ray signal, so if the X-ray generator and the X-ray detector Abnormal movement of the patient on the X-ray path, which may lead to dangerous collisions, cannot be accurately detected. For this reason, the inventor in the present invention overcomes the inertial thinking that the anti-collision device can only be set around the X-ray path, and proposes a new anti-collision implementation scheme for the X-ray detector to make up for the X-ray generator and the X-ray detector. The X-ray roads in between do not have the defect of anti-collision facilities.

[0030] In order to make the purpose, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

Abstract

The invention discloses an X-ray detector anti-collision device, method and proximity sensor thereof. The proximity sensor comprises a sensing antenna plate which is made of X-ray transmissive material and is positioned at one side, where X-ray signals are received, of the X-ray detector, for detecting the capacitance signals in a detected area; and an analog-to-digital conversion module which iselectrically connected with the sensing antenna plate and is used for converting the capacitance signals into digital capacitance values from analog quantity. The technical solution in the invention can realize the anti-collision protection of the X-ray detector.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to an X-ray detector anti-collision device, method and proximity sensor thereof. Background technique [0002] X-ray imaging equipment such as X-ray machines and X-ray photography systems generally include: X-ray generators (such as X-ray tubes) and X-ray detectors (such as flat panel detectors). Wherein, the X-ray generator is arranged opposite to the flat panel detector, and the object to be inspected (such as a human body) is placed between them. The X-ray generator is used to emit X-ray signals; the flat panel detector is used to obtain X-ray signals transmitted through the object to be inspected, and convert them into electrical signals, which are output to corresponding image processing modules for imaging. [0003] In order to perform multi-directional X-ray imaging inspection on the inspected object, the X-ray generator and / or the X-ray detector may have degrees of freedom ...
