Table 2 Reconstruction protocols (changes to standard protocol are marked in italics)

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
  1. OSEM ordered subsets expectation maximization, TOF time of flight, PSF point spread function
