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 one or more coronary arteries, and the patient-specific data including image data;
create a three-dimensional model representing at least a portion of the anatomical structure of the patient using the patient-specific data;
determine a myocardial mass of the patient using the patient-specific data;
estimate total coronary blood flow of the patient using the determined myocardial mass;
create a reduced-order blood flow model relating to a blood flow characteristic within the portion of the anatomical structure based, at least in part, on the estimated total coronary blood flow and the three-dimensional model;
create a multi-dimensional model using the three-dimensional model and the reduced-order blood flow model; and
determine a value of a fractional flow reserve at each of a plurality of locations within the portion of the anatomical structure using the multi-dimensional 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.
