A CAMAC BASED DATA-ACQUISITION SYSTEM FOR FLAT-PANEL IMAGE ARRAY READOUT

A readout system has been developed to facilitate the digitization and subsequent display of image data from two-dimensional, pixellated, fl at-panel, amorphous silicon imaging arrays. These arrays have been des igned specifically for medical x-ray imaging applications. The readout system is based on hardware and software developed for various experi ments at CERN and Fermi National Accelerator Laboratory. Additional an alog signal Processing- and digital control electronics were construct ed specifically for this application. We report on the form of the res ulting data acquisition system, discuss aspects of its performance, an d consider the compromises which were involved in its design.
