Some Noise Comparisons of Data-Collection Arrays for Emission Tomography-Systems Having Time-of-Flight Measurements

The noise performance of an emission tomography system having time-of-flight measurements is shown in several examples to be superior for a confidence-weighted data array compared to a most likely position data array. The examples range from a point to a planar distribution of radioactivity, and include a crude model of the left ventricle of a heart containing radioactive palmitate.
