OSEM - Nuclear Medical Imaging

Filtered Backprojection image quality can no longer be accepted as adequate.
See what an EM (Expectation Maximisation) method can do for your Nuclear Medical data (SPECT/PET).
Improved noise ratios and no streaking artifacts, could mean a better diagnosis.

OSEM (Ordered Subset EM) will give you the exact same quality as EM, faster.
