Description
Key Features
Fully Customizable Components
Scintillator Arrays: Available in BGO, LYSO, and GAGG, with fully customizable pixel sizes, array dimensions, and reflective layer types (e.g., BaSO₄, ESR). Optimize for sensitivity, decay time, or cost based on your application.
SiPM Detectors: Customizable pixel sizes, pitches, and array dimensions, ensuring optimal coupling with scintillator arrays for maximum light collection and minimal crosstalk.
Light Guides: Tailored to your system geometry, enhancing light transfer between scintillators and SiPMs to improve signal uniformity and detection efficiency.
Readout Electronics: Integrated CAPNET system with TDC (Time-to-Digital Converter)/ADC (Analog-to-Digital Converter) boards, providing high-precision timing and energy measurement without external components.
Exceptional Performance
ASIC-Level Performance: Matches the accuracy and speed of application-specific integrated circuit (ASIC) detectors, with energy resolution and timing precision suitable for high-resolution PET imaging.
Energy Resolution: ~9% (using LYSO scintillators), enabling clear discrimination of 511 keV gamma rays from positron annihilation—critical for reducing background noise and improving image contrast.
Coincidence Time Resolution: ~310 ps (using LYSO), supporting time-of-flight (TOF) PET capabilities to enhance spatial resolution and reduce scan duration.
Practical Advantages
Low Power Consumption: Approximately 1W per module, ideal for compact or battery-powered systems (e.g., portable PET scanners or preclinical setups with limited power budgets).
Modular Design: Simplifies scalable scanner construction—easily combine multiple modules to expand detector coverage (e.g., full-ring configurations for whole-body imaging).
Cost-Effective: Eliminates the need for custom ASIC development, reducing upfront engineering costs while maintaining high performance.
Technical Specifications
Scintillators include BGO, LYSO, and GAGG (with customizable pixel size, array size, and reflective layers). Detectors are SiPMs (with customizable pixel size, pitch, and array size). Light guides feature customizable geometry and material (e.g., acrylic, glass). Readout electronics consist of CAPNET plus integrated TDC/ADC boards. Performance is comparable to that of ASIC-based detectors, with a power consumption of approximately 1 W per module. The energy resolution (for LYSO) is approximately 9%, and the coincidence time resolution (for LYSO) is approximately 310.
