SYSTEMS AND METHODS FOR ESTIMATING ISCHEMIA AND BLOOD FLOW CHARACTERISTICS FROM VESSEL GEOMETRY AND PHYSIOLOGY
First Claim
1. A method for determining individual-specific blood flow characteristics, the method comprising:
- acquiring, for each of a plurality of individuals, individual-specific anatomic data and blood flow characteristics of at least part of the individual'"'"'s vascular system;
executing a machine learning algorithm on the individual-specific anatomic data and blood flow characteristics for each of the plurality of individuals;
relating, based on the executed machine learning algorithm, each individual'"'"'s individual-specific anatomic data to functional estimates of blood flow characteristics;
acquiring, for an individual, individual-specific anatomic data of at least part of the individual'"'"'s vascular system; and
for at least one point in the individual'"'"'s individual-specific anatomic data, determining a blood flow characteristic of the individual, using relations from the step of relating individual-specific anatomic data to functional estimates of blood flow characteristics.

Abstract
Systems and methods are disclosed for determining individual-specific blood flow characteristics. One method includes acquiring, for each of a plurality of individuals, individual-specific anatomic data and blood flow characteristics of at least part of the individual'"'"'s vascular system; executing a machine learning algorithm on the individual-specific anatomic data and blood flow characteristics for each of the plurality of individuals; relating, based on the executed machine learning algorithm, each individual'"'"'s individual-specific anatomic data to functional estimates of blood flow characteristics; acquiring, for an individual and individual-specific anatomic data of at least part of the individual'"'"'s vascular system; and for at least one point in the individual'"'"'s individual-specific anatomic data, determining a blood flow characteristic of the individual, using relations from the step of relating individual-specific anatomic data to functional estimates of blood flow characteristics.
