The DECTRIS SANTIS 0804 is the first detector dedicated to offer the spectral and low dose capabilities of Hybrid Photon Counting (HPC) technology to the medical imaging community. Where conventional detectors are limited in sensitivity, high-speed detection or energy resolution, the DECTRIS SANTIS 0804 offers all these possibilities in one measurement with no compromise.

The HPC technology provides a completely noise-free image acquisition process. Moreover, its CdTe sensor is optimally suited for applications where a high sensitivity to high-energy X-ray is a necessity (CT, fluoroscopy, SPECT), but also excels for applications like mammography. This unique combination of sensitivity and noise-free detection is an ideal prerequisite for dose minimization. With up to four energy bins available in one single exposure, it enables applications such as Spectral CT or energy resolved X-ray imaging with unparalleled precision. Increasing the discrimination between different tissues and multiple contrast media will extend the diagnostic potential of X-ray imaging.

The compact SANTIS 0804 paves the way towards these new applications and will allow you to evaluate its high resolution and spectral qualities. Empower yourself with HPC technology and explore new paths for medical imaging.
