Method and system for patient-specific modeling of blood flow
First Claim
1. A system for determining cardiovascular information for a patient, the system comprising:
- at least one computer system configured to;
receive patient-specific data regarding a geometry of an anatomical structure of the patient, the anatomical structure including at least a portion of a plurality of coronary arteries emanating from an aorta;
create a three-dimensional model representing a first portion of the anatomical structure based on the patient-specific data, the first portion of the anatomical structure including at least the portion of the plurality of coronary arteries;
create a physics-based model relating to a blood flow characteristic within the first portion of the anatomical structure based on, at least in part, a mass or a volume of myocardial tissue; and
determine a fractional flow reserve within the first portion of the anatomical structure based on the three-dimensional model and the physics-based model.

Abstract
Embodiments include a system for determining cardiovascular information for a patient. The system may include at least one computer system configured to receive patient-specific data regarding a geometry of the patient'"'"'s heart, and create a three-dimensional model representing at least a portion of the patient'"'"'s heart based on the patient-specific data. The at least one computer system may be further configured to create a physics-based model relating to a blood flow characteristic of the patient'"'"'s heart and determine a fractional flow reserve within the patient'"'"'s heart based on the three-dimensional model and the physics-based model.

12. A method for determining patient-specific cardiovascular information using at least one computer system, the method comprising:
-
inputting into the at least one computer system patient-specific data regarding a geometry of an anatomical structure of the patient, the anatomical structure including at least a portion of a plurality of coronary arteries emanating from an aorta; creating, using the at least one computer system, a three-dimensional model representing a first portion of the anatomical structure based on the patient-specific data, the first portion of the anatomical structure including at least the portion of the plurality of coronary arteries; creating, using the at least one computer system, a physics-based model relating to a blood flow characteristic within the first portion of the anatomical structure based on, at least in part, a mass or a volume of myocardial tissue; and determining, using the at least one computer system, a fractional flow reserve within the first portion of the anatomical structure based on the three-dimensional model and the physics-based model. - View Dependent Claims (13, 14, 15, 16)
