The overall objective of the proposed research is to advance large area active matrix flat panel detector (FPD) technology to enable emerging low photon fluence, real-time, large area, biomedical imaging applications such as 3D screening mammography tomosynthesis , protein crystallography, X-ray diffraction and scatter imaging. This will be accomplished by improving upon radiation detectors from a circuit, device and process level while using industry standard fabrication processes. The primary benefits of using the proposed approach is to leverage the capabilities of the well-established active matrix liquid crystal display (AMLCD) fabrication infrastructure and the mature silicon circuit design techniques developed over the past three decades. In this research, we address the key bottlenecks to the widespread adoption of FPD technology: dynamic range, spatial resolution and cost.
