Pixelated Semiconductor and Parallel ASIC Design for Spectral Clinical Radiology

William C. Barber, Einar Nygard, and Jan S. Iwanczyk

4.1 Introduction

This chapter focuses on the design of sensors and readouts for the development of X-ray imaging arrays for applications in clinical radiology. Clinical radiology is narrowly defined here as pertaining to the in vivo imaging of humans using X-ray photons. Silicon (Si)-based semiconductor and cadmium telluride (CdTe) and cadmium zinc telluride (CdZnTe) compound semiconductor sensor development using fast mixed signal application-specific integrated circuits (ASICs) as readouts that incorporate a portion of the digital readout are discussed with respect to their use in applications of spectral ...
