RADIOGRAPHY IMAGING SYSTEM HAVING AN ARRAY OF MICRO-ELECTROMECHANICAL (MEM) MIRRORS

Apparatus for radiography is disclosed, which includes a flat panel scintillator having a first surface for being exposed to radiation and a second surface for emitting visible light in response, and an associated imaging system. The imaging system includes a plurality of scanning MEM mirrors, each associated with a respective sub-region of the scintillator second surface, each scanning MEM mirror being mounted and controlled so as to re-direct light from along a predetermined scan path within the respective sub-region towards a respective optical channel. A photodetector is associated with each scanning MEM mirror and optical channel for receiving the re-directed light and generating an electrical signal representing light intensity. A processor receives the electrical signal from each photodetector and the corresponding position of each scanning MEM mirror to generate therefrom a reconstructed two-dimensional image.
