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.
Claims29
A system for determining neurovascular 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 plurality of cerebral arteries and at least a portion of brain tissue connected to the cerebral arteries;
- create a three-dimensional model representing the anatomical structure based on the patient-specific data;
- divide at least a portion of the three-dimensional model representing the brain tissue into segments;
- and
- determine perfusion information associated with at least one of the brain tissue segments based on the three-dimensional model and a physics-based model relating to the anatomical structure.
A method for determining patient-specific neurovascular information using at least one computer system, the method comprising:
- inputting into the at least one computer system patient-specific data regarding a geometry of an anatomical structure of the patient, the anatomical structure including at least a portion of a plurality of cerebral arteries and at least a portion of brain tissue connected to the cerebral arteries;
- creating, using the at least one computer system, a three-dimensional model representing the anatomical structure based on the patient-specific data;
- dividing, using the at least one computer system, at least a portion of the three-dimensional model representing the brain tissue into segments;
- and
- determining, using the at least one computer system, perfusion information associated with at least one of the brain tissue segments based on the three-dimensional model and a physics-based model relating to the anatomical structure.
A non-transitory computer readable medium for use on at least one computer system containing computer-executable programming instructions for performing a method for determining patient-specific neurovascular information, the method comprising:
- receiving patient-specific data regarding a geometry of an anatomical structure of the patient, the anatomical structure including at least a portion of a plurality of cerebral arteries and at least a portion of brain tissue connected to the cerebral arteries;
- creating a three-dimensional model representing the anatomical structure based on the patient-specific data;
- dividing at least a portion of the three-dimensional model representing the brain tissue into segments;
- and
- determining perfusion information associated with at least one of the brain tissue segments based on the three-dimensional model and a physics-based model relating to the anatomical structure.
