Calculation process of residence time for each organ using the PMOD Residence Times model. The process of defining VOI and deriving TAC in major organs is the same as that in the conventional method (A). Example window for calculating the residence time of the brain in the Residence Times model (B). Trapezoidal method chosen for calculating the AUC.
