From: Cardiac PET/CT with Rb-82: optimization of image acquisition and reconstruction parameters
Reconstruction protocols | Iterations × subsets | Filter FWHM (mm) | Difference vs. standard protocol (A) |
---|---|---|---|
(A) OSEM + TOF | 2 × 24 = 48 | 6 | – |
(B) OSEM + TOF | 4 × 16 = 64 | 6 | Higher iterations × subsets product |
(C) OSEM + TOF | 3 × 16 = 48 | 4 | Lower smoothing |
(D) OSEM + TOF | 2 × 16 = 32 | 6 | Lower iterations × subsets product |
(E) OSEM + TOF + PSF | 3 × 16 = 48 | 6 | With PSF recovery |
(F) OSEM + TOF | 3 × 16 = 48 | 8 | Higher smoothing |
(G) OSEM + TOF | 3 × 16 = 48 | 6 | Same product of iterations × subsets, but different iteration and subset |
(H) OSEM + no TOF | 3 × 16 = 48 | 6 | No TOF correction |
