Method and system for patient-specific modeling of blood flow

摘要

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.

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 patient's coronary arteries; create a three-dimensional model of at least an area of interest within the portion of the patient's coronary arteries using the received patient-specific data; generate a reduced-order model of a second area of the portion of the patient's coronary arteries that is adjacent to the area of interest and coupled to the three-dimensional model of at least the area of interest; solve equations of blood flow through the portion of the patient's coronary arteries using the three-dimensional model and the reduced-order model; and calculate a value of a blood flow characteristic within at least the area of interest using one or more solutions to the equations of blood flow.
