ABSTRACT:
A solid state x-ray detector which is a two-dimensional array of individual pixel elements is described. The hybrid semiconductor construction produces detector elements with high spatial resolution (<30 microns), high sensitivity to the entire x-ray spectrum, and frame rates greater than 1000 Hz. In a biomedical application these arrays provide high quality real time digital radiographic images that are directly coupled to an image processing system for image enhancement and computer aided diagnosis. In an alternative embodiment of the invention, the hybrid construction incorporated into an automated manufacturing process facilitates the real time, nondestructive, x-ray examination of manufactured objects during the production process. Structural defects in inorganic objects under test are identified in real time during the manufacturing process are corrected when feedback signals are generated from the electronic image data generated during the nondestructive test process.
