A flat panel detector system and its fast wake-up method

Abstract

The invention provides a flat panel detector system and a rapid awakening method thereof. The flat panel detector system comprises, at least, an X-ray sensor, a standby voltage stabilizing circuit, an acquisition circuit, a main CPU control processing unit, an image display unit, a battery unit, a low-noise voltage stabilizing circuit, a switching power supply and an auxiliary CPU power supply management unit. The auxiliary CPU power supply management unit is used for providing standby and awakening time sequence control of a flat panel detector and meanwhile conducts powering-on and powering-off control on the battery unit, the low-noise voltage stabilizing circuit and the switching power supply respectively. Standby and awakening time sequence control is conducted on the flat panel detector by adding the auxiliary CPU power supply management unit, and when the flat panel detector is standby, powering on for the X-ray sensor is kept, and meanwhile part of circuit constitution unit is closed to reduce the standby power consumption of the flat panel detector. In addition, the flat panel detector can be rapidly awakened, and improvement of clinical experience of a user is promoted.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to a flat panel detector system and a fast wake-up 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 fast wake-up method, which is used to solve the problem that the X-ray sensor in the prior art has a large leakage current when it is in standby for a long time and cannot be quickly cleared. problems, and the long power-on time of the X-ray sensor, which leads to the problem that the wake-up time of the flat panel detector is too long
