The AS5920M Photon Counting Module is a pre-production technology optimized for spectral computed tomography (CT) detectors. This innovative solution comprises a 72x24 pixel, four-side buttable module that combines three AS5920 photon counting ICs alongside essential passive components. The design facilitates electrical connections to direct conversion sensor materials like CdTe or CZT, converting X-ray photons into charge pulses effectively.
Engineered for high precision, the AS5920M ensures the accurate counting of X-ray photon-generated charges, with each charge pulse's amplitude corresponding to the deposited photon energy. The module excels in scenarios requiring meticulous energy discrimination, using configurable energy thresholds for optimal power management. Its distinct paralyzable and non-paralyzable counting modes enhance output count rates, demonstrating adaptability across different medical imaging environments.
The AS5920M is ideal for next-generation CT imaging, where lower-dose and high-resolution diagnostics are critical. It features a low-noise charge sensitive amplifier, achieving excellent electronic noise levels, and supports complex medical imaging needs with its advanced photon counting capabilities. This module's robust performance is complemented by an integrated digital interface for seamless data transmission and thermal management, ensuring longevity and reliability in demanding applications.
