DMatrix gamma-ray detector/imager

A perfect introduction into CZT nuclear imaging

The DMatrix Nuclear Imager is a fully integrated photon counting pixilated, 12-Bit energy discriminating CZT detector/imager. Modular design enables large field of view scaling.

The solid-state detector technology, cadmium zinc telluride (CZT), provides superior efficiency and energy discrimination capabilities vs. conventional Scintillation-based detectors.

CZT detectors coupled with Kromek’s advanced ASIC technology make spectroscopic photon=counting gamma imaging possible. CZT based detectors are rapidly becoming the technology of choice in many of today’s most advanced medical, industrial, and security applications.
