Movies acquired from fundus imaging using Indocyanine Green (ICG) and a scanning laser ophthalmoscope provide information for identifying vascular and other retinal abnormalities. Today, the main limitation of this modality is that it requires esoter

1990 IEEE Nuclear Science Symposium Conference Record.
A new computer system designed for Posi- tron Emission Tomography (PET) devices that utilize list- mode data acquisition and Time-of-Flight(ToF) information is presented. The approach uses commercially available subsys- tems, all supported by hardwar

Conference Record of the 1991 IEEE Nuclear Science Symposium and Medical Imaging Conference.
Specifications were developed for a PET (positron emission tomography) system that emphasizes high-count-rate performance and is specifically designed for the estimation of myocardial perfusion using oxygen-15 water and dynamic imaging protocols. The

One recent development in image reconstruction utilizing time-of-flight information yields a compression of the three dimensional array used in forming the unfiltered "preimage." A reduction from 96 angles to 16 angles is shown to produce equivalent
