Abstract
A spherical positron emission tomograph (S-PET) is proposed and its performance analyzed. Computer modelling and simulation studies indicate that a high resolution and high sensitivity positron emission tomograph having a spatial resolution of 2–3 mm fwhm can be realized with acceptable imaging time and sensitivity.
Multilayer S-PET having 16–24 layers is specifically analyzed and compared with its corresponding cylindrical counterpart. The result shows that the sensitivity gain of the spherical system is a factor 3 over the cylindrical system with identical true to scatter and random ratios.
