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.
Claims28
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 at least a portion of an anatomical structure of the patient, the anatomical structure including at least a portion of a plurality of arteries and myocardial tissue connected to at least some of the plurality of arteries;
- create a three-dimensional model representing the anatomical structure of the patient based on the patient-specific data;
- divide at least a portion of the three-dimensional model representing the myocardial tissue into segments;
- and
- determine perfusion information associated with at least one of the segments based on the three-dimensional model and a physiological condition of the patient.
A method for determining cardiovascular information for a patient using at least one computer system, the method comprising:
- receiving, using at least one computer system, patient-specific data regarding a geometry of at least a portion of an anatomical structure of the patient, the anatomical structure including at least a portion of a plurality of arteries and myocardial tissue connected to at least some of the plurality of arteries;
- creating, using the at least one computer system, a three-dimensional model representing the anatomical structure of the patient based on the patient-specific data;
- extending, using the at least one computer system, the three-dimensional model to form an augmented model;
- dividing, using the at least one computer system, at least a portion of the augmented model representing the myocardial tissue into segments;
- and
- determining, using the at least one computer system, perfusion information associated with at least one of the segments based on the augmented model and a physiological condition of the patient.
A non-transitory computer readable medium for use on a computer system containing computer-executable programming instructions for performing a method for determining cardiovascular information for a patient, the method comprising:
- receiving patient-specific data regarding a geometry of at least a portion of an anatomical structure of the patient, the anatomical structure including at least a portion of a plurality of arteries and myocardial tissue connected to at least some of the plurality of arteries;
- creating a three-dimensional model representing the anatomical structure of the patient based on the patient-specific data;
- dividing at least a portion of the three-dimensional model representing the myocardial tissue into segments;
- and
- determining perfusion information associated with at least one of the segments based on the three-dimensional model and a physics-based model relating to the anatomical structure.
