Abstract
The present disclosure provides a voltage calibration device, method and imaging system. The voltage calibration device, comprising: a channel selector and a calibration unit, wherein an input end of the channel selector is selectively connected to channels to be calibrated of multiple detectors to receive a common mode voltage of each channel to be calibrated; a first input end of the calibration unit is connected to an output end of the channel selector, an output end of the calibration unit is connected to the multiple channels to be calibrated, the calibration unit adjusting the common mode voltage of each channel to be calibrated to a calibrated common mode voltage to cause each channel to be calibrated to be detected under its corresponding calibrated common mode voltage.
