Automated LA Segmentation

Objective

The goal of this project is to implement Gopal and Ross' segmentation method: "Left atrial wall segmentation using intensity profile based feature detector and optimal graph-cuts." Our objective is to implement this method in Slicer. There are several fairly involved steps for the entire segmentation process, including:

1. An LA shape model building phase
2. User input to identify the center of a region of interest
3. Computation of the segmentation, given a new LGE-MRI image
4. Surface reconstruction of the output point set and (optionally) scan-conversion of the surface mesh to a binary segmentation volume.

Approach, Plan

1. We plan to implement this algorithm as a Slicer command-line module.

Progress

Delivery Mechanism

This work will be delivered to the NA-MIC Kit as a Slicer module as part of the existing Cardiac MRI Toolkit extension.
