Abstract
The University of Connecticut Health Center and Xicon Technologies, LLC have been developing a high speed/high resolution x-ray detector called the XEBIT (X-ray sensitive Electron Beam Image Tube). The XEBIT is a direct conversion image detector that uses Thallium Bromide as the x-ray photoconductor. thallium bromide is a high Z material with a linear attenuation coefficient of 28.11 cm-1 at 60 keV. This high stopping power results in a quantum efficiency in excess of 50% at 60 keV for 300 micron thick layers. The XEBIT has far superior contrast resolution with over 50 percent modulation at 5 line pairs per millimeter and does not suffer from veiling glare. This paper is a report on the works in progress of the XEBIT development, which s near clinical trials.
