Method and Apparatus for High Efficiency X-ray Imager


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 readout and excellent image quality, AMFPI is being used not only for traditional x-ray imaging modalities such as general radiography and fluoroscopy, but also in tomographic imaging applications.


The detectors proposed here provide an improved dynamic range and sensitivity which is required in digital radiography. Improving optical photon conversion efficiency provides practical advantages for both avalanche and non-avalanche embodiments of the scintillator.


This 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 green and red wavelengths.
