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.
Claims23
A system for determining patient-specific time-varying cardiovascular information, the system comprising:
- at least one computer system configured to:
- receive time-varying patient-specific data regarding a geometry of at least a portion of an anatomical structure of the patient at different times;
- create a three-dimensional model representing at least the portion of the anatomical structure of the patient based on the time-varying patient-specific data, the three-dimensional model including time-varying information regarding at least one of blood vessel position, deformation, orientation, or size;
- and
- determine information regarding a change in a blood flow characteristic over time within the anatomical structure of the patient based on the three-dimensional model and a physics-based model relating to the anatomical structure of the patient.
A method for determining patient-specific time-varying cardiovascular information using at least one computer system, the method comprising:
- receiving, using at least one computer system, time-varying patient-specific data regarding a geometry of at least a portion of an anatomical structure of the patient at different times;
- creating, using the at least one computer system, a three-dimensional model representing at least the portion of the anatomical structure of the patient based on the time-varying patient-specific data, the three-dimensional model including time-varying information regarding at least one of blood vessel position, deformation, orientation, or size;
- and
- determining, using the at least one computer system, information regarding a change in a blood flow characteristic over time within the anatomical structure of the patient based on the three-dimensional model and the information regarding a physics-based model relating to the anatomical structure 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 patient-specific time-varying cardiovascular information, the method comprising:
- receiving time-varying patient-specific data regarding a geometry of at least a portion of an anatomical structure of the patient at different times;
- creating a three-dimensional model representing at least the portion of the anatomical structure of the patient based on the time-varying patient-specific data, the three-dimensional model including time-varying information regarding at least one of blood vessel position, deformation, orientation, or size;
- and
- determining information regarding a change in a blood flow characteristic over time within the anatomical structure of the patient based on the three-dimensional model and the information regarding a physics-based model relating to the anatomical structure of the patient.
