Abstract: A computer-implemented method of determining data indicating volumetric flow rate within an artery. The method comprises receiving data indicating a proximal pressure measurement relative to a direction of blood flow; receiving data indicating a distal pressure measurement relative to the direction of blood flow; wherein the proximal pressure measurement and the distal pressure measurement are obtained using at least one pressure transducer; receiving geometric model data representing the artery, wherein the geometric model data is generated based upon image data indicative of the artery; and computing a volumetric flow rate with in the artery, wherein computing comprises performing a numerical simulation of blood flow through the artery based upon the geometric model data, the data indicating a proximal pressure measurement and the data indicating a distal pressure measurement.
