摘要: As part of the development necessary for implementing a fully digital radiology department, authors have investigated thin-film photodiodes and transistors use in new photoelectronic imaging devices. One such device, large-area, flat-panel, amorphous silicon array, has been developed is currently being tested. The array format 512 x 560 pixels, pixel-to-pixel pitch 450 microns, an area 230 252 mm2, making it largest self-scanning, solid-state to date. used conjunction with overlying x-ray converter. Although specifically designed megavoltage imaging, device can produce high-quality, low spatial resolution, diagnostic images. Qualitative comparisons images anthropomorphic head, chest, pelvic phantoms resolution pattern suggest that much information content film at present corresponding Current trends th...
