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;
create a three-dimensional model representing at least a portion of the anatomical structure of the patient based on the patient-specific data, the three-dimensional model representing at least one fluid flow inlet and at least one fluid flow outlet;
create at least one boundary condition model representing fluid flow through at least one of the at least one inlet or the at least one outlet, based at least in part on modeling a condition of hyperemia; and
determine first information regarding a blood flow characteristic within the anatomical structure of the patient based on the three-dimensional model and the at least one boundary condition 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.
