In this study, we introduce compartment modeling into quantitative transport mapping (QTM), with the goal of mapping both the blood flow and the tracer exchange between vascular space and extravascular space. The nonlinear optimization problem is solved using the Levenberg–Marquardt method. We validate two compartment QTM (2c-QTM) in a porous media simulation and apply this method to dynamic PET data.
