Abstract
Systems and methods are disclosed for correcting for artificial deformations in anatomical modeling. One method includes obtaining an anatomic model; obtaining information indicating a presence of an artificial deformation of the anatomic model; identifying a portion of the anatomic model associated with the artificial deformation; estimating a non-deformed local area corresponding to the portion of the anatomic model; and modifying the portion of the anatomic model associated with the artificial deformation, based on the estimated non-deformed local area.
Claims20
A computer-implemented method of correcting anatomical modeling, the method comprising:
- obtaining an anatomic model including a patient's vasculature;
- obtaining information indicating a presence of an artificial deformation of the anatomic model;
- identifying a portion of the anatomic model associated with the artificial deformation;
- estimating a non-deformed anatomic dimension of a blood vessel of the patient's vasculature;
- and
- modifying the portion of the anatomic model associated with the artificial deformation, based on the estimated non-deformed anatomic dimension.
A system for correcting anatomical modeling, the system comprising:
- a data storage device storing instructions for correcting anatomical modeling;
- and
- a processor configured to execute the instructions to perform a method including:
- obtaining an anatomic model including a patient's vasculature;
- obtaining information indicating a presence of an artificial deformation of the anatomic model;
- identifying a portion of the anatomic model associated with the artificial deformation;
- estimating a non-deformed anatomic dimension of a blood vessel of the patient's vasculature;
- and
- modifying the portion of the anatomic model associated with the artificial deformation, based on the estimated non-deformed anatomic dimension.
A non-transitory computer readable medium for use on a computer system containing computer-executable programming instructions for performing a method of correcting anatomical modeling, the method comprising:
- obtaining an anatomic model including a patient's vasculature;
- obtaining information indicating a presence of an artificial deformation of the anatomic model;
- identifying a portion of the anatomic model associated with the artificial deformation;
- estimating a non-deformed anatomic dimension of a blood vessel of the patient's vasculature;
- and
- modifying the portion of the anatomic model associated with the artificial deformation, based on the estimated non-deformed anatomic dimension.
