Abstract

The invention provides a wireless charging device for an X-ray flat panel detector, comprising: a power transmission circuit, including: an AC-DC module, a drive circuit, an active coil, a voltage / current sensor, and a first communication control circuit; a power receiving circuit Circuit, including: passive coil, rectifier circuit, voltage conversion circuit, and second communication control circuit. To charge the battery of the flat panel detector, just install the wireless charging transmitter on the cassette frame (Bucky) of the digital X-ray imaging system (DR system); in terms of EMC, there is no external charging cable, and the EMC shielding performance of the whole machine is greatly improved. Optimization improves the anti-interference characteristics of the X-ray flat panel detector and reduces the EMI radiation of the flat panel detector to the outside; in terms of reliability, it avoids reliability problems caused by the use of external cables.

Description

technical field [0001] The invention relates to a charging device, in particular to a wireless charging device for an X-ray flat panel detector. Background technique [0002] Since the launch of the first flat panel detector (flat panel detector) equipment in 1995, with the rapid development of flat panel detector technology in recent years, many manufacturers and researchers have taken the flat panel detector digital X-ray detector from the laboratory Bringing it to clinical use, due to the advantages of high sensitivity, wide dynamic range and low distortion of digital images of flat-panel detectors, hospital users are increasing, and flat-panel technology is gradually becoming popular. The backbone of the diagnostic radiology imaging revolution. Flat-panel image sensors, especially large-scale image sensors, usually have an area of ​​tens of centimeters and millions to tens of millions of pixels. Usually used in medical radiation imaging, industrial flaw detection, secu...
