This work presents the development of a novel detector comprised of an avalanche amorphous selenium (a-Se) photoconductor and an amorphous silicon (a-Si:H) passive pixel sensor for digital X-ray imaging, in particular, for low exposure imaging applications. Electrical compatibility of a high voltage (~1000 V) avalanche a-Se photoconductor with a low voltage… CONTINUE READING
