New high resolution block detectors were developed for positron emission tomographs (PET), in which BGO scintillators are coupled to a position-sensitive photomultiplier tube (PMT). The block detectors using two different structure of BGO scintillators were constructed and evaluated: one is 1.7 mm wide BGO array which provides the coincidence detector resolution less than 2 mm fwhm, and the other is a BGO block having comb-shape slits in it which has a potential capability of improving the resolution uniformity of a PET system because of its ability to detect the depth-of-interaction of {gamma}-rays in the scintillator. They are applied to a PET system for animal studies under development.
