Crystal Identification in Positron Emission Tomography Using Probabilistic Graphical Models

Determining the location of crystals within detector arrays (position profile) is a crucial part of system tuning in Positron Emission Tomography (PET) scanners. It provides a basis for the mapping of detected events and the most probable crystal location to assign the event. Accurate assignments ar...
