When is a photon counting detector the right choice? When the application requires features such as ultra-fast X-ray imaging, material discrimination, and high performance at low dose.

Our direct conversion photon counting technology uses CdTe/CdZnTe to directly convert photons to energy without the need for a scintillator. Detectors based on photon counting technology have intrinsic properties including very high spatial resolution, very high contrast to noise ratio, multi-energy capabilities, high X-ray absorption and sensitivity and high efficiency.

The DC-TDI series of very fast, dual energy, photon counting detectors are ideal for line scan applications such as high-speed inspection, and are based on our unique and patented ASIC design and technology including TDI and charge-sharing correction.
