Abstract:
1. A method for generating a dynamic aortic valve model, comprising: receiving a 4D cardiac image sequence comprising a plurality of frames, each frame comprising 3D image data; determining an initial estimate for a physiological aortic valve model in at least one reference frame of the plurality of frames based on anatomical landmarks in the at least one reference frame; refining the initial estimate for the physiological aortic valve model in the at least one reference frame using boundary detection to generate a final estimate for the physiological aortic valve model in the at least one reference frame; and generating a dynamic aortic valve model by estimating the physiological aortic valve model for remaining frames of the plurality of frames based on the final estimate for the physiological aortic valve model in the at least one reference frame.
