Relationship between %contrast and image noise using different reconstruction conditions. OSEM (circles), BPL with (white squares) and without (black squares) PSF correction. Curves for BPL with and without PSF correction run from left to right with increasing β values (β = 50–1000). Dotted lines, reference standards of contrast (horizontal) and noise (vertical) for image quality acceptance in Japanese Society of Nuclear Medicine phantom tests. BPL, Bayesian penalised likelihood; OSEM, ordered subset-expectation maximization; PSF, point-spread-function
