Abstract
Official abstract text for this publication.
A method and system for automated intervention planning for transcatheter aortic valve implantations using computed tomography (CT) data is disclosed. A patient-specific aortic valve model is detected in a CT volume of a patient. The patient-specific aortic valve model is detected by detecting a global location of the patient-specific aortic valve model in the CT volume, detecting aortic valve landmarks based on the detected global location, and fitting an aortic root surface model. Angulation parameters of a C-arm imaging device for acquiring intra-operative fluoroscopic images and anatomical measurements of the aortic valve are automatically determined based on the patient-specific aortic valve model.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for intervention planning for a transcatheter aortic valve implantation, comprising: detecting a patient-specific aortic valve model in a computed tomography (CT) volume of a patient by: detecting a global location of the patient-specific aortic valve model in the CT volume, detecting a plurality of aortic valve landmarks in the CT volume based on the detected global location of the patient-specific aortic valve model, and fitting an aortic roo…
