Abstract
Systems and methods are disclosed for determining a patient risk assessment or treatment plan based on emboli dislodgement and destination. One method includes receiving a patient-specific anatomic model generated from patient-specific imaging of at least a portion of a patient'"'"'s vasculature; determining or receiving a location of interest in the patient-specific anatomic model of the patient'"'"'s vasculature; using a computing processor for calculating blood flow through the patient-specific anatomic model to determine blood flow characteristics through at least the portion of the patient'"'"'s vasculature of the patient-specific anatomic model downstream from the location of interest; and using a computing processor for particle tracking through the simulated blood flow to determine a destination probability of an embolus originating from the location of interest in the patient-specific anatomic model, based on the determined blood flow characteristics.

21. A computer-implemented method of determining a patient risk assessment or treatment plan based on emboli dislodgement and destination, the method comprising:
-
receiving a patient-specific anatomic model generated from patient-specific imaging of at least a portion of a patient'"'"'s vasculature; determining or receiving a location of interest in the patient-specific anatomic model of the patient'"'"'s vasculature; computing, using a computing processor, a blood flow characteristic of blood flow through at least the portion of the patient-specific anatomic model downstream from the location of interest; determining, using the computing processor, a velocity field of the computed blood flow; and computing, using the computing processor, a destination probability of an embolus originating from the location of interest in the patient-specific anatomic model, based on the computed blood flow and the determined velocity field; and computing, using the computing processor, a likelihood of the location of interest being an embolic source, based on the determined destination probability. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28)
