Scanner Components and Function

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

Image Reconstruction and Quantification

Accessible explanations of filtered back projection, iterative reconstruction, time of flight (TOF), point spread function modeling, 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, uniformity and flood phantom scans, coincidence timing checks for PET, and documentation of software updates and service events.
