PET Detectors and Coincidence Electronics
NMI 110 delves into the core components and sophisticated electronics powering modern medical imaging systems. Beginning with an exploration of various scintillator materials, the course progresses to the critical role of photomultiplier tubes and silicon photomultipliers in converting light signals into electrical impulses. A significant focus is placed on the principles of coincidence detection, which underpins the accurate localization of annihilation events. Students will learn about the precise timing requirements, including the impact of time-of-flight measurements on image quality and signal-to-noise ratios. The curriculum also covers the essential techniques for detector normalization and calibration, crucial for maintaining system accuracy and reliability. Furthermore, the course addresses the technical considerations involved in integrating these detection systems with complementary imaging modalities, preparing technicians for advanced roles in equipment maintenance, calibration, and troubleshooting.
