Abstract
The exciting possibilities of regional, noninvasive and quantitative metabolic studies of the brain with positron emission tomography, have initiated the construction of a second generation positron camera system at the Department of Physics, University of Stockholm, in collaboration with the Departments of Neuroradiology, Clinical Neurophysiology and Radiation Physics at the Karolinska Hospital and Institute, and the Instrument AB Scanditronix. The camera is a four ring system with 96 bismuth germanate (BGO) detectors per ring. The spatial resolution is 7.7 mm FWHM and the sensitivity per μCi per ml for a 20 cm diameter cylinder phantom is 25000 c/s for direct slices and 35000 c/s for cross slices.Keywords
