Paper Abstract

The design and construction of a prototype high resolution digital x-ray imaging system, employing a novel scintillating microfiber detector as the x-ray imaging sensor is described. The fiber detector has an active imaging area of 5 cm X 5 cm and thickness of 1 cm. The optical image formed in the fiber detector is read out by a high resolution image intensifier- CCD camera system. Investigations on the image quality of the prototype x-ray system are reported. MTF measurement shows >= 10 line pairs/mm spatial resolution of the scintillating fiber detector over the diagnostic x-ray energy range. The feasibility of the medical diagnostic application of the scintillating fiber detector is analyzed, and the new sensor is shown to be adaptable to imaging tasks where both high resolution and high detector sensitivity are required.
