Description
This paper reports on the performance of a pair of multi-crystal, high resolution, bismuth germanate (BGO) block detectors for positron emission tomograpy (PET). Utilizing the detectors ar a separation of 100 mm, the spatial resolutions have been measured in the two axes of the block. These measurements indicate maximum spatial resolutions of 3.6 and 4.5 mm (FWHM). The system has been used to observe the regional kinetics of positron-emitting radionuclides in the rat brain sand the human radial artery. Designs for a small diameter, no-septa tomograph incorporating these detectors have been considered. Simulations performed demonstrate the possibilities of following tracer uptake within the rat brain and radial artery. 3D tomographic data-sets acquired from a uniform cylinder, obtained by rotating the two detectors, indicate good uniformity in the field of view (FOV) of 25 mm
