A CMOS photodetector array with in-pixel electronics has been developed for computed tomography (CT) applications. Current CT detectors are based on two discrete components: a photodiode array and a data acquisition system (amplifier). Both elements have to fulfill a series of severe requirements. CT scanners are moving toward larger detectors and higher speed, and yet lowering costs and improving performance. This contribution relates to the integration of both elements into a standard CMOS… CONTINUE READING
