Image processing and HMR calculation. a Images with different energy window widths (symmetrical, ± 2.5%, 5.0%, 7.5%, 10%, 20%, and 40%) using a fixed collection time (300 s). b Images with different collection times (25, 50, 100, and 200 s) using a fixed window width (± 5.0%). c The regions of interest (ROIs) manually set on the heart (52.5 cm2, oval-shaped) and mediastinum (10.5 cm2, square-shaped) in the anterior and posterior planar views. d Relationship between energy (x-axis) and radioactive counts (y-axis) and set energy peak ± window widths (vertical white lines)
