US Patent 8120683 High resoultion digital imaging apparatus

An integrated application specific integrated circuit having a detection layer, a time delayed integration capability, data acquisition electronics, and a readout function is provided for detecting breast cancer in women. The detection layer receives x-ray radiation and converts the received energy to electron pairs, one of which is received by pixels. The time delay integration is on the chip and a part of the readout architecture. The detector may be a hybrid silicon detector (SiPD), a CdZnTe detector, or a GaAs detector.
