Description

In the context of position emission tomography, the selection of a time window which allows for subtraction of random coincidences in a statistically optimal sense is discussed. Descriptions are given of the sampling properties of ring systems when the ring remains stationary, undergoes half rotation, or precesses. The extent of the attenuation problem is demonstrated and the principle of a novel approach towards it is described. (orig.)
