'It's amazing' – the wonder material very few can make
Summary
A special material called cadmium zinc telluride (CZT) helps create detailed 3D images in medical scanners and has other uses like detecting radiation. Kromek, a company in the UK, is one of the few that can make this material. The process to create CZT involves a precise and long manufacturing method.Key Facts
- CZT helps improve medical imaging, especially for conditions like long Covid.
- The new scanner at Royal Brompton Hospital in London uses CZT to cut lung scan times from 45 minutes to 15 minutes.
- Kromek, a UK company, is one of the few capable of producing CZT.
- CZT is also used in X-ray telescopes and airport security scanners.
- The scanner requires less radioactive substance due to CZT's sensitivity.
- Manufacturing CZT involves heating powder in special furnaces, then forming a single-crystal structure.
- CZT detects photons in X-rays and gamma rays with high precision.
- CZT-based technology is used for explosives detection in airports and might be applied to hand luggage checks soon.
