Ultra-high resolution sensor. ARISTO is a high resolution, self-triggering X-ray sensor designed for small field of view imaging. High resolving power is achieved with an ultra-fine pitch directly converting silicon (Si) sensor.


USB interface and self-triggering ensure ease of use and compatibility with any X-ray source in the range of 10 to 70 kVp.

The basic component in our detectors is a direct conversion material, which converts the X-rays into electrical signals, and a CMOS (ASIC) which transforms the electric signals into a data stream of either the integrated electric charge or the number of photons which has entered each pixel. This data is then used to create a digital image which is either two- or three-dimensional, depending on the scan geometry.
