Paper Abstract

Progress toward the development of a large area, flat-panel imager for diagnostic x-ray imaging is described. The initial fabrication of a prototype array with a format of 1536 X 1920 pixels and a pixel pitch of 127 micrometers giving an active area of 19.5 X 24.4 cm2 is reported. With a total of approximately 2.9 million transistors, this ambitious array is on a par with modern microprocessors in terms of transistor count. This work builds upon our concurrent research into the development of a very large area, lower spatial resolution, flat-panel imager for radiotherapy. An overview of the anticipated imaging properties of these devices is presented and future prospects discussed.
