Kromek secures five-year contract for gamma detectors
Kromek secures five-year contract for gamma detectors under the terms of the contract, Kromek will supply its cadmium zinc telluride-based (CZT) detector modules for incorporation in the customer’s products. The density of CZT means that its incorporation significantly improves the sensitivity of positive detection of cancerous tumours.
Dr Arnab Basu, CEO of Kromek, said: “I am pleased to receive this long-term contract from our existing customer reaffirming their commitment for the next five years. This is a result of the high-quality products and services we have provided them throughout the last few years. We are continuing to develop new business opportunities in our core markets while serving our existing customers, which are important for the continuing growth of the business.”
Application of CZT in detection equipment
Since the early 1990s, Cadmium Zinc Telluride (CZT) detector has remained as the only realistic detector material which can be used as an alternative to germanium (in term of operating temperature) and an alternative to scintillator (in term of energy resolution).
The demand for CZT continues to grow, driven mainly by 3 major fields of applications
- Medical application.
- Homeland security.
- Scientific research.
Current use of CZT in medical imaging
Currently, CZT is used in detectors deployed in intra-operative surgery guidance, measuring bone density, dental x-rays and SPECT cameras. CZT is popular in mammography and cardiology.
Kromek’s CZT advantage
Our current crystal growth of CZT (also known as CdZnTe) is based on the scalable advanced technology of the travelling heater method at two CZT factories one in the UK and one in the USA. Our CZT manufacturing process gives us the ability to produce high quality, large single crystals with great electrical transport properties and unmatched uniformity. Growing great CZT crystals is only half the story, the crystals then need to be incorporated into the detector electronics. Our detector assemblies build upon our existing high-volume and quality manufacturing capabilities already used in our SPECT and CBRNe detectors.
