System for diagnosing bloodflow characteristics, method thereof, and computer software program

A system for evaluating a vascular surgical technique, the system comprising a computer configured to:

• receive a first three dimensional data representing a shape of a vascular portion to which the vascular surgical technique has been applied, and
• determine information relating to an energy loss of blood flow at a vascular portion, by conducting computational flow dynamics (CFD) simulations using the first three dimensional data, the energy loss representing a quality of the surgical technique.

A method for evaluating a vascular surgical technique, comprising the steps of:

• receiving a first three dimensional data representing a shape of a vascular portion to which the vascular surgical technique has been applied, and
• determining information relating to an energy loss of blood flow at a vascular portion, by conducting computational flow dynamics (CFD) simulations using the first three dimensional data, the energy loss representing a quality of the surgical technique.

The method of claim 76, further comprising the step of

• determining a disturbance based on at least a relative relationship among directions of wall shear stress vectors at and around each computational mesh on the inner surface of the vascular portion of the patient.
