Classification: CPC G | IPC G

Claim 0:
1. A system, comprising:
an intravascular catheter or guidewire comprising a pressure sensor configured to collect a plurality of pressure measurements in-situ from only a first branch of a vessel tree, wherein the vessel tree includes the first branch and a different, second branch; and
a processor configured for communication with the intravascular catheter or guidewire, wherein the processor is configured to:
receive medical image data of the vessel tree;
receive the plurality of pressure measurements;
generate a geometrical model based on the medical image data;
perform spatial registration of the plurality of pressure measurements to the geometrical model based on an association between each of the plurality of pressure measurements and a location within the first branch where the pressure sensor collected the respective pressure measurement;
automatically set first boundary conditions for the first branch based on the spatial registration;
compute, based on the first boundary conditions and the geometrical model, at least one of a first flow value or a first resistance value for the first branch;
extrapolate at least one of a second flow value or a second resistance value to the second branch; and
output to a display in communication with the processor:
the medical imaging data;
a visualization of the plurality of pressure measurements overlaid on the first branch in the medical imaging data;
a visualization of at least one of the first flow value or the first resistance value overlaid on the first branch in the medical imaging data; and
a visualization of at least one of the second flow value or the second resistance value overlaid on the second branch in the medical imaging data,

wherein, to extrapolate, the processor is configured to:
automatically set second boundary conditions for the second branch based on the first boundary conditions and the geometrical model; and
compute, based on the geometrical model and the second boundary conditions, at least one of the second flow value or the second resistance value for the second branch.
