The AS5920M Photon Counting Module from ams OSRAM is an advanced solution for spectral computed tomography detectors, offering a 1728-channel system-in-package configuration. This module integrates three proprietary AS5920 photon counting ICs, enhancing precision in medical imaging by converting each X-ray photon into charge pulses. The technology supports low-dose diagnostic imaging by ensuring detailed energy discrimination and minimal noise through a high-speed LVDS interface mode. With its modular design enabling intimate integration with direct conversion sensor materials, this module promises reduced power dissipation while maintaining optimal performance.
