Method and system for patient-specific modeling of blood flow

A system for determining patient-specific cardiovascular information, 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;
• determine, for each of a plurality of portions of the anatomical structure of the patient, a resistance associated with flow through each of the plurality of portions, wherein the resistance is determined based on resistance values associated with other patients' patient-specific data;
• and
• determine information regarding a blood flow characteristic within the anatomical structure of the patient based on the three-dimensional model and a second model generated based on the determined resistances.

A method for determining patient-specific cardiovascular information using at least one computer system, the method comprising:

• receiving, in the at least one computer system, patient-specific data regarding a geometry of an anatomical structure of the patient;
• creating, using the at least one computer system, a three-dimensional model representing at least a portion of the anatomical structure of the patient based on the patient-specific data;
• determining, using the at least one computer system, for each of a plurality of portions of the anatomical structure of the patient, a resistance associated with flow through each of the plurality of portions, wherein the resistance is determined based on resistance values associated with other patients' patient-specific data;
• and
• determining, using the at least one computer system, information regarding a blood flow characteristic within the anatomical structure of the patient based on the three-dimensional model and a second model generated based on the determined resistances.

• and
• determining, using the at least one computer system, information regarding a blood flow characteristic within the anatomical structure of the patient based on the reduced-order model.
