SNAP 225

Powered By Ajat Technology

Dental sensor (panoramic, cephalometric). The SNAP 225 sensor is designed for dental X-ray imaging systems in both panoramic and cephalometric modalities and in fixed as well as moveable sensor configurations.

The unparalleled imaging performance produced by the CdTe-CMOS technology is coupled with industry standard Gigabit Ethernet interface and flexible software solutions.

All Varex/Direct Conversion imaging receptors are designed to be integrated into a complete X-ray system by a qualified system integrator. The system integrator is responsible for obtaining FDA clearance for medical use or appropriate CE marking.

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.
