Claim 20:
21. A system, comprising:
a memory to receive 3D data representing a vessel segment of a vasculature and measured flow data representing measurements of flow in the vessel segment; and
one or more processors to
determine a 0D model of the vessel segment based on static fluid simulations of the vessel segment using the 3D data, wherein the 0D model includes a respective inductor and a respective pressure source for each of a plurality of subsegments extending between an inlet and a plurality of outlets of the vessel segment, and wherein values of the pressure sources are taken from a response surface of the static fluid simulations of the vessel segment,
generate simulated flow data representing flow in the vessel segment based on a first vascular system model including a reduced order model of the vessel segment coupled to a 0D model of a remainder of the vasculature, wherein the reduced order model represents flow in the vessel segment in real-time, and wherein the reduced order model is based on the 0D model of the vessel segment, and
adjust the 0D model of the remainder of the vasculature based on a comparison of the simulated flow data to the measured flow data.
