Abstract

A method for performing segmentation on CT image data of a spine is provided. The method includes retrieving the CT image data of the spine, detecting an estimated position of at least four pedicle regions associated with a plurality of vertebras, determining a pose for each of at least two vertebrae. The method further includes performing a first segmentation process on the CT image data with a shape model to generate a first segmentation and performing a second segmentation process on the CT image data using a first neural network to generate a second segmentation of the at least two vertebrae. The method also includes mapping the shape model to the second segmentation, applying landmarks from the shape model to the second segmentation using the mapping, and overlaying a segmentation mask based on the second segmentation over the CT image data.
