Amorphous selenium (a-Se) is a photoconductive material that has been intensively
investigated from its early application in xerography to its present application in flat panel X …

Amorphous selenium (a-Se) is a glass-former capable of deposition at high rates by thermal
evaporation over a large area. It was chosen as a direct conversion material due to its …

Solution processable perovskites have made remarkable strides in direct planar X-ray
detectors, promising to reshape X-ray detector industry. Herein, we discuss prevailing …

This work reports an edge enhancing effect experimentally observed in cadmium telluride
(CdTe)-based photon counting detector (PCD) systems operated under the charge summing …

In this work, we report the nature of formation in the presence and absence of Ag

Contrast-enhanced digital mammography using spectroscopic x-ray detectors may improve
image quality relative to existing contrast-enhanced breast imaging approaches. We present …

Due to pulse pileup, photon counting detectors (PCDs) suffer from count loss and energy
distortion when operating in high count rate environments. In this paper, we studied the …

The basic principle of operation of an x-ray detector is described through the Shockley-
Ramo theorem, and the ionization energy, ie, electron and hole pair creation energy, is …

Amorphous selenium (a-Se) is a high gain, low dark current, large area compatible
photoconductor that has received significant attention towards the development of UV and X …

Purpose Photon counting arrays (PCA s), capable of measuring the spectral information of
individual x‐ray photons and recording that information digitally, provide a number of …
