Enhanced user interface and crosstalk analysis for vascular index measurement

A system comprising one or more processors and non-transitory computer storage media storing instructions that when executed by the one or more processors, cause the one or more processors to perform operations comprising:

• accessing a cardiac model of a portion of a patient's heart, the portion including one or more vessels of the patient's heart, and the cardiac model indicating a plurality of lesions along a length of at least one of the vessels;
• obtaining, based on the cardiac model for the lesions, respective positions along the length for which the lesions are associated with index drops, wherein the index drops are with respect to an index indicative of vascular function for the vessels;
• and
• based on information indicating that a particular lesion of the plurality of lesions is to be nulled, updating the index indicative of vascular function to null effects of the particular lesion.

Non-transitory computer storage media storing instructions that when executed by a system of one or more computers, cause the one or more computers to:

• access a cardiac model of a portion of a patient's heart, the portion including one or more vessels of the patient's heart, and the cardiac model indicating a plurality of lesions along a length of at least one of the vessels;
• obtain, based on the cardiac model for the lesions, respective positions along the length for which the lesions are associated with index drops, wherein the index drops are with respect to an index indicative of vascular function;
• and
• cause presentation of a user interface, wherein the user interface:
• presents a graph mapping individual positions along the length of the vessel and values of the index indicative of vascular function,
• presents individual user interface elements enabling nulling of individual lesions, and
• updates the graph in response to received user input to one or more of the user interface elements, wherein the user input nulls effects of one or more lesions.
