Flat panel detector system and power supply method thereof

Abstract

The invention provides a flat panel detector system and a power supply method thereof. The flat panel detector system at least comprises an X-ray sensor, a collecting drive circuit, a main CPU control processing unit, an image display unit, a battery unit, a battery charging unit, an outer input power supply and an auxiliary CPU power supply management unit; the auxiliary CPU power supply management unit is used for detecting whether or not a working power source which externally supplies power exists or not, conducting image collecting and sequential control of charge control mutual exclusion on the collecting drive circuit and the battery charging unit when the working power source which externally supplies power exists, and then adjusting the battery charging current of the battery charging unit on a battery. According to the flat panel detector system and the power supply method thereof, by adding the auxiliary CPU power supply management unit to conduct sequential control on the image collecting and battery charging, the flat panel detector can be allowed to conduct battery charging under the situation that the image collecting is not influenced, the overall power dissipation is reduced, and the requirement on clinic portable application is met.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to a flat panel detector system and a power supply method thereof. Background technique [0002] Digital Radiography (Digital Radiography, referred to as DR), is a new technology of X-ray photography developed in the 1990s. With its remarkable advantages such as faster imaging speed, more convenient operation, and higher imaging resolution, it has become It is the leading direction of digital X-ray photography technology and has been recognized by clinical institutions and imaging experts all over the world. The technical core of DR is the flat panel detector, which is a sophisticated and expensive device that plays a decisive role in the imaging quality. The flat panel detector is the X-ray receiving device in the DR system. In the DR system, the high-voltage generator and the ball tube control the output of X-rays. The X-rays pass through the object and are attenuated. Then i...

Problems solved by technology

[0006] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a flat panel detector system and its power supply method, which is used to solve the problem of simultaneous image acquisition and Fast charging of the battery will cause its overall power consumption to be large, resulting in a high temperature rise of the X-ray sensor, and a large leakage current during standby, which cannot be quickly cleared, thus affecting the image quality.
