Method for determining and correcting the response stability of a semi-conductor matrix detector

摘要

The method involves associating unstable pixels of a semi-conductor imaging device with stable pixels according to a predetermined criterion. The stable and unstable pixels of the imaging device are irradiated by radiation to be characterized during a predetermined time. Signals delivered by each pixel are stored for a time interval taken during the predetermined time. The signals generated by each unstable pixel are corrected based on the signals generated by the stable pixels to which the unstable pixels are associated. An independent claim is also included for a semi-conductor imaging device comprising a storing unit for storing signals delivered by pixels.
