A modified orthogonal-distance ray-tracer method applied to dual rotation PET systems

a new projector, orthogonal-distance ray-tracer varying-full width at half maximum (OD-RT-VF), was developed to model a shift-variant elliptical point-spread function (PSF) response to improve the image quality (IQ) of a preclinical dual-rotation PET system. the OD-RT-VF projector models different F...
