  The Multigap Resistive Plate Chambers (MRPCs) provide excellent timing as
well as position resolutions at relatively low cost. Therefore, they can be
used in medical imaging applications such as PET where precise timing is a
crucial parameter of measurement. We have designed and fabricated several
six-gap glass MRPCs and extensively studied their performance. In this paper,
we describe the fabrication and characterization of the detector, the
electronics and the data acquisition system of the setup. We present here the
result of our Time Of Flight (TOF) experiment using a radioactive source Na-22
hence to demonstrate their potential applications in medical imaging. We also
present the Geant4 based simulation results on the efficiency of our detector
as a function of the number of gaps and thickness of the converter material.
