1. A computer implemented method for generating a 3D image of a patient specific anatomic feature from 2D medical images, the method comprising:
automatically pre-processing a set of 2D medical images to identify critical features of the patient specific anatomic feature based on a downstream preoperative planning application;
automatically generating a 3D image from the pre-processed set of 2D medical images;
using a machine learning based image segmentation technique to segment the generated 3D image;
determining one or more parameters of the patient specific anatomic feature from the segmented 3D image; and
automatically determining one or more structural parameters of a physical medical device selected for the downstream preoperative planning application based on the one or more parameters of the patient specific anatomic feature.
