Fig. 7From: Ejection fraction in myocardial perfusion imaging assessed with a dynamic phantom: comparison between IQ-SPECT and LEHRCardiac phantom volume estimates for LEHR and IQ-SPECT protocols compared with corresponding CT measurements (small dot) with phantom EF setting 65%. The effect of the number of reconstruction iterations (EI) is shown with different markers (cross = 2, square = 12 and large dot = 34)Back to article page
