Abstract :
We compare the maximum likelihood and convolution-backprojection reconstructions of a particular real phantom with count data obtained from the Columbia University Positron Emission Tomographic Scanner, Dichotom II. We find the maximum likelihood reconstruction reduces noise and streak artifacts confirming earlier work with simulated count data.
