Receiver operating characteristic (ROC) analysis of images reconstructed with iterative expectation maximization algorithms.

abstract：:Attenuation correction is very important for quantitative SPECT imaging. We designed an uncollimated non-uniform line array source (non-uniform LAS) for attenuation correction based on transmission computed tomography (TCT) using Tc-99m and compared its performance with an uncollimated uniform line array source (unifo...
