Line profiles over a reconstructed myocardium with the myocardiac insert in an empty torso. On the left are three long-axis images, corresponding to 40, 80, and 100 iterations. The summed profile was calculated from the seven rows in between the yellow markings and includes the data for every 20th iteration. Only alternate data points are marked for clarity. The reference activity concentration, shown by a horizontal dotted line, in the myocardium at the start of the measurement was 0.18 MBq/mL
