The imager will have thecapability to replace currently used x-ray film cassettes. The X-ray detection is achieved by means of fluorescent screen. An image formed on a fluorescent screen during exposure is captured by an array of charge-coupled-devices. CCD image sensors are read out by a high-speed, parallel channel design electronics. Overlaps between the image segments, as a result of array configuration, are removed, and the final image is displayed on a medium to high resolution display. For the purpose of portability, an LCD display and a compact size microcomputer unit are used in the system. However the system can be adapted to any other computer system or display unit with ease. The imaging system also includes number of image processing algorithms available to the operator for further refinement of the images.
