Medical applications of CdTe and CdZnTe detectors

This review on the medical applications of CdTe and CdZnTe semiconductors is an update on the 1992 and 1996 papers [1]. In addition, future trends in the application of these semiconductors to the medical field are presented and discussed. Several solid-state detectors, based on direct or indirect detection principles, have been proposed for digital radiography and radionucleide imaging applications, although there is no single technology of choice that addresses all the issues for optimal imaging. CdTe/CdZnTe semiconductor substrates are promising digital sensors for medical imaging applications. The widespread use of these detectors depends on the large-scale production of low-cost, large-size semiconductor substrates.
