摘要：An imaging system () includes a direct conversion detector pixel () that detectsradiation traversing an examination region and generates an electrical signal indicative
thereof, wherein the signal includes a persistent current, which is produced by a directconversion material of the pixel and which shifts a level of the signal. A persistent currentestimator () estimates the persistent current and generates a compensation signal basedon the estimate. A pre-amplifier () receives the signal and the compensation signal,wherein the compensation signal substantially cancels the persistent current, producing apersistent current compensated signal, and that amplifies the compensated signal,generating an amplified compensated signal. A shaper () generates a pulse indicative ofenergy of the radiation illuminating the direct conversion material based on the amplifiedcompensated signal.
