Paper Abstract

Direct detection of x-ray using the technology of selenium on Thin Film Transistor (TFT) has been used in a number of medical imaging and other products for almost 10 years. The spatial resolution of this Direct Conversion Technology with MTF approaches the theoretical Sinc Function remains unsurpassed. However, there are rooms for improvement in several areas that may further advance the performance. This paper is to examine some of these areas and to explore potential solutions.
