We present techniques and systems for a CZT gamma camera head based on an array of discrete CZT detectors and associated front-end electronics. In Section I, we describe the performance of a small 256 detector (16 /spl times/ 16) CZT imager in terms

Some insulating GaAs and CdTe:Cl photoconductor probes were qualified on high energy X-ray single-shot flash generators. The estimated minimum detected dose per flash corresponding to a 230 mrad direct beam attenuated by 200 mm lead was 20 μ rad. Th

A new high energy X-ray chlorine doped cadmium telluride (CdTe:Cl) photoconductor is described. We discuss different deposition techniques (sputtering, evaporation, electroless) to realize ohmic contacts which have low leakage current and which allow

Monolithic CdZnTe detectors are promising for medical and small animal imaging because of a good energy resolution that allows both multi-drug diagnostic and scatter event rejection. Optimizations of electrode geometry and detector thickness are used
