Scanner Components and Function

Describes PET detector components including scintillators, photodetectors or solid state detectors, coincidence electronics, gantry and bed mechanics and explains how each component affects sensitivity, spatial resolution, and timing performance.

Image Reconstruction and Quantification

Accessible explanations of iterative reconstruction, time of flight (TOF), point spread function modeling, attenuation correction, and partial volume effects and how reconstruction choices affect quantitative accuracy and lesion detectability.

Routine Equipment Checks

A practical checklist for daily and periodic checks students should observe: energy window verification, flood and uniformity phantom scans, coincidence timing checks, PET/CT alignment checks, and documentation of software updates and service events.
