Learn advanced techniques for reconstructing particle interactions within scintillator detectors specifically designed for Positron Emission Tomography (PET) imaging systems. Explore the fundamental principles of how scintillator materials convert high-energy photons into detectable light signals, and master the computational methods used to accurately determine the location, energy, and timing of gamma-ray interactions within the detector volume. Discover the challenges associated with Compton scattering, photoelectric absorption, and multiple interaction events that can degrade image quality in PET scanners. Examine sophisticated algorithms and mathematical models used to distinguish between different types of interactions and reconstruct the original photon paths with high precision. Understand how proper interaction reconstruction directly impacts the spatial resolution, sensitivity, and quantitative accuracy of PET imaging systems used in medical diagnostics and research applications. Gain insights into the latest developments in detector technology, including depth-of-interaction measurements, time-of-flight capabilities, and advanced signal processing techniques that enhance the performance of modern PET scanners.
