With optimized solid-state sensors and CMOS readout ASICs using hybrid pixel technology, Hybrid Photon Counting Detectors provide direct sensing of every single photon in X-ray. HPC technology achieves high signal-to-noise ratio via noise-free signal with no dark current. Detectors also deliver high data rates via dedicated ASIC and electronic design, exclusive spectral information via energy analysis, and high spatial resolution via direct detection, without scintillators or fiber optics.
