Project Goal: A Slicer Module to compute the endocardial surface minus pulmonary veins (the light blue region). Requires an input endocardial surface (orange) and wall segmentation (green).

The standard CARMA clinical MRI processing workflow involves several segmentation steps, and we seek to implement our entire workflow in Slicer. The goal of this project is to fill one of the current gaps in the processing pipeline, which is to produce an LA endocardial surface segmentation that includes only the antrum regions of the pulmonary veins. There are no image features that define this boundary, but we have developed some heuristic criteria. Given a completed LA wall segmentation and a completed endocardial segmentation (blood pool), we have developed a simple algorithm to automatically compute the endocardium with PV antrum regions. The goal of this project is to implement this algorithm in Slicer.

Objective

1. Port existing CARMA C++ code for PV Antrum Cutting to command-line Slicer module
2. Test and Document Module
3. Deploy in CARMA Extension Module

Approach, Plan

We plan to package existing C++ code as a command-line module. There are no parameters for the algorithm, so the user interface will be relatively straightforward. Some work in advance of the Programmer's Week has already been done. By the end of the week, we expect to have a working module to deploy online through our CARMA Extension.
