Medical applications of CdTe and CdZnTe detectors

This review on the medical applications of CdTe and CdZnTe semiconductors i s 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 d etection principles, have been proposed for digital radiography and radionu cleide imaging applications, although there is no single technology of choi ce that addresses all the issues for optimal imaging. CdTe/CdZnTe semicondu ctor substrates are promising digital sensors for medical imaging applicati ons. The widespread use of these detectors depends on the large-scale produ ction of low-cost, large-size semiconductor substrates. (C) 2001 Elsevier S cience B.V. All rights reserved.
