SWITCHING/DEPOLARIZING POWER SUPPLY FOR A RADIATION IMAGING DEVICE

摘要

A high voltage switching power supply ( 10 ) for an X-ray/Gamma ray imaging camera provides high voltage switching and depolarization capabilities. The power supply includes a high voltage polarity switching and an image detector charge bleeding circuit ( 90 ) and is particularly useful with high energy radiation imaging cameras utilizing Cd-Te based detector substrates, especially substrates with blocked contacts, where charge accumulation in the detector material reduces imaging efficiency.
