Abstract

Several X-ray imaging techniques are reviewed, and the use of amorphous silicon detector arrays for X-ray imaging is discussed. An important aspect of the amorphous silicon technology is the large size of the image sensor array, which is particularly significant for radiation imaging because it is not presently possible to focus X-rays over large fields of view. Current techniques allow an array size of about 10 in*10 in. Several medical applications for imaging arrays, including radiation therapy, real-time fluoroscopy, diagnostic radiographic imaging, and nuclear medicine techniques are also discussed.<>
