CZT gamma imaging components

CZT and medical imaging

Cadmium zinc telluride (CZT also written as CdZnTe) is a room-temperature semiconductor radiation detector that has many uses in medical imaging, especially in single photon emission computed tomography (SPECT). CZT camera solutions are used in positron emission tomography (PET) and x-ray radiography computed tomography (CT) as well as bone mineral densitometry (BMD, DEXA) and photon-counting spectral CT. We have developed a variety of CZT gamma detector components that can be used by medical equipment manufacturers to build devices using CZT as the imaging medium.

Kromek CZT components for medical imaging

We offer a range of CZT components for use by OEMs developing new medical equipment and refurbishing old models. The smaller size and weight of CZT gamma detectors (compared to existing scintillation detectors) have created a market for medical imaging devices that are smaller with improved portability and that open up new operating techniques, for example, lower tracer dose, faster scan times, earlier diagnosis and using multiple tracers in one examination.

4D spectral-spatial CZT gamma detectors create a step-change in the performance of diagnostic imaging systems including SPECT (molecular imaging), bone mineral densitometry (BMD, DEXA), surgical probes and colour photon-counting computed tomography (CT). The change is akin to moving from black-and-white vacuum-tube television to a colour digital high-definition flat screen. Higher resolution means clearer, more detailed images which make the job of diagnosis easier, with higher accuracy and diagnostic confidence at earlier stages of heart disease, cancer, osteoporosis and, increasingly, dementia.

The overall impact is increased patient safety and care, lower overall healthcare costs and increased efficiency in hospitals.
