Patent ID: 7601962

Claim:
A method for reading data using an imaging system, comprising a detector that comprises a first semiconductor device, a second semiconductor device, and a photodiode, the first semiconductor device and the second semiconductor device coupled to the photodiode, said method comprising: applying a first voltage to at least one data line coupled to the first semiconductor device using sensing circuits coupled to the at least one data line, the sensing circuits configured to maintain the at least one data line at a substantially constant potential; applying a second voltage to a maintenance control electrode coupled to the second semiconductor device to maintain a bias across the photodiode, the first semiconductor device coupled to the photodiode; applying a third voltage to a maintenance potential electrode coupled to the second semiconductor device to maintain the bias across the photodiode; deactivating the second semiconductor device after receiving an exposure request, wherein deactivating the second semiconductor terminates the application of the second voltage and the third voltage; exposing the detector to radiation; reading image data from the detector after the exposure has terminated, the image data read via at least one scan line coupled to the first semiconductor device; and reapplying the second voltage and the third voltage.
