Abstract
Embodiments of the present disclosure provide a reading apparatus for an X-ray detector, a method for using the reading apparatus, and the X-ray detector. The reading apparatus includes a control circuit, a compensation circuit, and a processing circuit. The control circuit is configured to provide, in a first phase, a first signal to an input terminal of the compensation circuit according to a reference signal and a dark current in a sense device of the X-ray detector, and provide, in a second phase, a second signal from the sense device to the input terminal of the compensation circuit. The compensation circuit is configured to generate, in the first phase, a compensation signal according to the first signal, and compensate, in the second phase, the second signal according to the compensation signal, to generate a third signal. The processing circuit is configured to process the third signal.
