Popis: A readout system has been developed to facilitate the digitization and subsequent display of image data from two-dimensional, pixellated, flat-panel, amorphous silicon imaging arrays. These arrays have been designed specifically for medical X-ray imaging applications. The readout system is based around hardware and software developed for various experiments at CERN and the Fermi National Accelerator Laboratory. Additional analog signal processing and digital control electronics were constructed specifically for this application at Michigan. The authors report on the form of the resulting data acquisition system, discuss aspects of its performance, and consider the compromises which were involved in its design. Although there are some features of the resulting system which are not optimized for the particular application (e.g., analog noise considerations and data transfer bandwidth), it has been possible to perform numerous investigations of the signal and noise characteristics of these imaging devices. In addition, the first diagnostic and megavoltage images of anatomical detail have been generated, thereby verifying the concept of this new detector technology. >
