MILabs similarity-regulated ordered-subsets expectation maximisation algorithm (srosem)
Contrast-to-noise ratio (CNR) of the investigated collimators with optimized values for each rod size by Gaussian post-filtering (full width half maximum = rod size). Bar charts compare the image quality of the collimators XUHR-M, GP-M and UHS-M for different activity levels in the mini Derenzo phantoms 850.500 and 850.100. In addition, the graphs in ( c ), ( e ) and ( g ) show how the 3DT-Scanner with the same GP-M collimator and a pixel-based ordered-subset expectation <t>maximisation</t> (POSEM) reconstruction algorithm compares to the new 2DT-Scanner and the similarity-regulated ordered-subset expectation maximisation <t>(SROSEM)</t> algorithm. Time per bed position (TPB) was 300 s with at least 9 bed positions (BP), corresponding to a total scan duration of 45 min
