We describe the prototype of a full-body PET scanner for rats that is compatible with a 9.4 T MRI system. The detector consists of 96 PET detector blocks in a cylindrical arrangement. In this paper we concentrate on a new readout technology, which takes advantage of the fact that optical fibers are insensitive to electromagnetic interference. The data are formatted in a FPGA on the motherboard and...
The feasibility of performing high-resolution PET and high-field MRI simultaneously in rodents has been previously demonstrated in small-scale systems capable of imaging the rat brain and mouse. We are nearing completion of a larger scale PET system which will accommodate the whole rat and perform at 9.4 T with <2 mm PET resolution. The PET insert has inner/outer diameters of 13.5/20.6 cm,...
