High voltage x-ray and conventional radiography imaging apparatus and method
摘要
A detector (20) for high voltage x-rays includes a plurality of sensor elements (22) with each sensor element being aligned along a respective focal axis (25) with respect to a high voltage x-ray source (24). A fiber optic scintillator (34) is optically coupled to each of said sensor elements and is disposed to receive incident x-ray radiation passing from the object to be imaged. Optical fibers of the scintillator are positioned such that their optical axes are perpendicular to incident x-rays. Each sensor element has a length along the focal axis sufficiently long for the fibers to absorb substantially all incident x-rays. Each sensor element comprises an array of amorphous silicon photosensors disposed to detect light generated by the scintillator.
