Method and system for patient-specific modeling of blood flow
First Claim
1. A system for determining patient-specific cardiovascular information, the system comprising:
- at least one computer system configured to;
receive patient-specific data regarding a geometry of an anatomical structure of the patient;
create a three-dimensional model representing at least a portion of the anatomical structure of the patient based on the patient-specific data;
determine, for each of a plurality of portions of the anatomical structure of the patient, a resistance associated with flow through each of the plurality of portions, wherein the resistance is determined based on resistance values associated with other patients'"'"' patient-specific data; and
determine information regarding a blood flow characteristic within the anatomical structure of the patient based on the three-dimensional model and a second model generated based on the determined resistances.

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.

21. A method for determining patient-specific cardiovascular information using at least one computer system, the method comprising:
-
receiving, in the at least one computer system, patient-specific data regarding a geometry of an anatomical structure of the patient; creating, using the at least one computer system, a three-dimensional model representing at least a portion of the anatomical structure of the patient based on the patient-specific data; determining, using the at least one computer system, for each of a plurality of segments of the anatomical structure of the patient, a resistance associated with blood flow through each of the plurality of segments, wherein the resistance is determined based on resistance values stored in relation to corresponding segments of other patients'"'"' anatomical structure; generating a reduced-order model of blood flow through the portion of the anatomical structure of the patient based on a plurality of resistance values determined for each of the plurality of segments; and determining, using the at least one computer system, information regarding a blood flow characteristic within the anatomical structure of the patient based on the reduced-order model.
