Analysis process of different acquisition and reconstruction parameters. The process started with six subsets, no filter, AC + SC + RR correction combination, 120 s/frame of acquisition time, and 15% energy window. The impacts of iterations, subsets, FWHM, correction combination, energy window, and acquisition time/frame were evaluated in sequence and an optimal value of these parameters was determined in each step of the process
