RADIOGRAPHIC DETECTOR WITH A TRAP OCCUPATION CHANGE MONITOR AND FEEDBACK, AN IMAGING DEVICE, AND A METHOD FOR USING THE SAME CAPABLE OF REDUCING A POTENTIAL LOSS OF IMAGE QUALITY

摘要

PURPOSE: A radiographic detector with a trap occupation change monitor and feedback, an imaging device, and a method for using the same are provided to improve medical digital radiographic technology.;CONSTITUTION: A plurality of pixels include an optical sensor. The optical sensor is arranged on a region detector. A bias control circuit(232) provides a bias voltage to the optical sensor to charge the optical sensor. At least one sensor provides a read value in response to light transmitted to the optical sensor. An optical sensor trap occupation change monitor is connected to at least one optical sensor to measure the trap occupation change of the optical sensor.;COPYRIGHT KIPO 2013;[Reference numerals] (228) Gate driver; (232) Bias bus; (286) Charge amplifier; (287) Multiplexer; (A1,A2,284) Data line; (B1,B2,285) Bias line; (C1,C2,283) Gate line
