Fig. 5From: Ejection fraction in myocardial perfusion imaging assessed with a dynamic phantom: comparison between IQ-SPECT and LEHREFLEHR and EFIQSPECT estimates as a function of number of reconstruction equivalent iterations for the dynamic heart phantom, analysed using a QGS and b 4DM software. The phantom was imaged with 45, 55, 65 and 70% EF settings (grey solid line)Back to article page
