Fig. 3

Relationship between %contrast and image noise (CV) with the reconstruction parameter (96 iterative updates: iteration = 6 and subset = 16) and different post-filters (2, 4, and 6 mm FWHM Gaussian filter) for an old PET camera model measured with the phantoms under flutemetamol condition. Ninety-six iterative updates and other iterative updates (80 and 128, data not shown) did not satisfy the criteria (shaded region)
