Publikováno v: Physics in Medicine and Biology
Physics in Medicine and Biology; Vol 56
Iterative image reconstruction methods such as ordered-subset expectation maximization (OSEM) are widely used in PET. Reconstructions via OSEM are however reported to be biased for low-count data. We investigated this and considered the impact for dy
