Wherein, the last module circuit includes a differential circuit, a buffer circuit, a generation circuit for data storage and control time sequence, a data storage circuit, a network SCM, an accelerator CP isolation drive circuit, a process circuit for accelerator beam strength information, and a constant voltage power circuit.

Description

technical field [0001] The invention relates to the technical field of radiation detection, in particular to a system for controlling a detector in radiation imaging by using a data acquisition and control module circuit. Background technique [0002] Radiation imaging system includes ray source, detector, data acquisition and control, image inspection, mechanical electronic control, safety chain and other parts. In the prior art, the output of the detector module is an analog signal, and the corresponding control system also uses an analog signal. The signal anti-interference ability is poor, the system structure is complex, and data acquisition and transmission are inconvenient. With technological progress and the emergence of new digital chips, the digitalization of detector modules can be completed at low cost. The use of digital detector modules requires corresponding data acquisition and control modules to control them. Therefore, a new data acquisition and control mo...
