A Proof- of-Principle for Time of Flight-Positron Emission Tomography Imaging

Time of Flight (TOF) is a noble technique that is used in Positron Emission Tomography (PET) imaging worldwide. Scintillator based imaging system that is being used around the world for TOF-PET is very expensive. Multi-gap Resistive Plate Chambers (MRPCs) are gaseous detectors which are easy to fabricate, inexpensive and have excellent position and timing resolution. They can be used as a suitable alternative to highly expensive scintillators. For the sole purpose of TOF-PET, pair of 18 cm \(\times \) 18 cm, 5 gap, glass based MRPC modules have been fabricated. Our main aim was to determine the shift in the position of source (Na-22) with these fabricated MRPCs. In this document the details of the experimental results will be presented.
