Nuclear Medicine Software Suite
The HERMES HOSEM program is an iterative reconstruction program which uses the Ordered Subset Expectation Maximization (OSEM) algorithm. It can be used to reconstruct studies acquired in any matrix size over any number of angles with a parallel hole or fanbeam collimator. The program can reconstruct data acquired from cameras with 1, 2 or 3 heads.
