Spectral resolution and high-flux capability tradeoffs in CdTe detectors for clinical CT.

Norbert J Pelc, Paurakh L Rajbhandary, Scott S Hsieh
Photon counting detectors using CdTe or CZT substrates are promising candidates for future CT systems but suffer from a number of non-idealities, including charge sharing and pulse pileup. By increasing the pixel size of the detector, the system can improve charge sharing characteristics at the expense of increasing pileup. The purpose of this work is to describe these considerations in the optimization of the detector pixel pitch.
