Abstract :
A novel way of measuring the non-proportional response of scintillation materials, using a Positron Emission Tomography (PET) scanner, has been developed and tested. Using a Siemens Biograph mCT, a modified Compton coincidence technique is performed where the Compton scatter angular information data is collected by taking advantage of the fine angular sampling that is inherent to the PET scanner. Using the scatter angle information, the energy deposited in the sampled scintillator can be calculated. Comparing the calculated energy deposited versus the measured scintillator response yields the Compton electron non-proportional response.
