Abstract
A computer implemented method for assessing an arterio-venous malformation (AVM) may include, for example, receiving a patient-specific model of a portion of an anatomy of a patient; using a computer processor to analyze the patient-specific model for identifying one or more blood vessels associated with the AVM, in the patient-specific model; and estimating a risk of an undesirable outcome caused by the AVM, by performing computer simulations of blood flow through the one or more blood vessels associated with the AVM in the patient-specific model.
Claims20
A computer implemented method for assessing an arterio-venous malformation (AVM), the method comprising:
- receiving image data of at least a portion of a vascular system of a patient, including one or more blood vessels having at least one vessel wall associated with the AVM;
- generating a patient-specific three-dimensional anatomic model of the portion of the vascular system of the patient, using the received image data;
- identifying, using a computer processor, features of the one or more blood vessels having the AVM;
- identifying, using a computer processor, a blood vessel of the patient-specific three-dimensional anatomic model;
- performing a blood flow simulation through the identified blood vessels having the AVM;
- identifying one or more largest blood vessels associated with the AVM;
- and
- generating a treatment recommendation for treating the AVM of the identified blood vessel based on the performed blood flow simulation and based on the identified largest blood vessels associated with the AVM.
A system for assessing an arterio-venous malformation (AVM), the system comprising:
- at least one data storage device storing instructions for assessing an arterio-venous malformation (AVM);
- and
- at least one processor configured to execute the instructions to perform a method comprising:
- receiving image data of at least a portion of a vascular system of a patient, including one or more blood vessels having at least one vessel wall associated with the AVM;
- generating a patient-specific three-dimensional anatomic model of the portion of the vascular system of the patient, using the received image data;
- identifying, using a computer processor, features of the one or more blood vessels having the AVM;
- identifying, using a computer processor, a blood vessel of the patient-specific three-dimensional anatomic model;
- performing a blood flow simulation through the identified blood vessels having the AVM;
- identifying one or more largest blood vessels associated with the AVM;
- and
- generating a treatment recommendation for treating the AVM of the identified blood vessel based on the performed blood flow simulation and based on the identified largest blood vessels associated with the AVM.
A non-transitory computer readable medium storing computer-executable programming instructions for performing a method of non-invasively assessing a risk of a clinical event in a patient, the method comprising:
- receiving image data of at least a portion of a vascular system of a patient, including one or more blood vessels having at least one vessel wall associated with an arterio-venous malformation (AVM);
- generating a patient-specific three-dimensional anatomic model of the portion of the vascular system of the patient, using the received image data;
- identifying, using a computer processor, features of the one or more blood vessels having the AVM;
- identifying, using a computer processor, a blood vessel of the patient-specific three-dimensional anatomic model;
- performing a blood flow simulation through the identified blood vessels having the AVM;
- identifying one or more largest blood vessels associated with the AVM;
- and
- generating a treatment recommendation for treating the AVM of the identified blood vessel based on the performed blood flow simulation and based on the identified largest blood vessels associated with the AVM.
