i-RASE aims to deliver a novel radiation sensor system using real-time AI for enhanced detection and imaging.
Embedded artificial neural networks for on-the-fly detector signal processing and event classification reduce data bottlenecks and surpass conventional offline analysis (cutting conventional event data size from ~50 KB/event to ~16 bytes/event for the 3D CZT DSD test detector). The system allows a direct connection to sensor signals for near-real-time, comprehensive signal processing, enabling the extraction of incident radiation information much faster and accurate.
Unified System-in-Package
Analog signal conversion, digital electronics, and AI are integrated into a single, compact, low-power system-in-package (SIP).
Physics-Informed Models
Synthetic data generation paired with real measurements accelerates robust ANN training and detector optimization. A potential IPR for a new ML method—combining physics-based parameters with real detector signals in an ANN-driven simulator—is under discussion.
Potential Impacts
Healthcare and Security: Faster, more accurate imaging and threat detection systems.
Environmental and Space: High-precision radiation monitoring with minimal hardware footprint, featuring intelligent on-board event processing software for background suppression and an improved signal-to-noise ratio based on radiation and interaction-type classification.
