Abstract

We have developed e prototype PET detector which is compatible with a clinical MRI system to provide simultaneous PET and MR imaging. This single- slice PET system consists of 48 2 x 2 x 10 mm³ LSO crystals in a 38 mm diameter ring configuration that can be placed inside the receiver coil of the MRI system, coupled to three multi-channel photomultipliers housed outside the main magnetic field via 4 m long and 2 mm diameter optical fibres. The PET system exhibits 2 mm spatial resolution, 41% energy resolution at 511 keV and 20 ns timing resolution. Simultaneous PET and MR phantom images were suceessfully acquired.
