Method and Apparatus for High Efficiency X-ray Imager

Through the rapid development of large-area AMFPI based on amorphouse silicon active matrix technology, it will become the dominant dector technology in x-ray imaging.

X-ray imaging experienced a "digital revolution" in the early 2000s, with digital radiography systems being implemented with active matric flat panel images.Due to the compact size, rapid image read out and excellent image quality, AMFPI is being used not only for traditional x-ray imaging modalities such as general radiography and fluroscopy, but also in tomographic imaging applications.

Proposed detectors provide a improved dynamic range and sensitivty which is required in digital radiography. Improving optical photon conversion effciency, provides practical advantages for both avlanche and non-avalanche emodiments of scintillator.

Technology improves the quantum efficiency of indirect and hybrid x-ray imagers where optical photons need to be converted to electronic charge. The improvement in quantum efficiency can be orders of magnitude for greena and red wavelengths.
