General Information

Module Type & Category

Type: CLI

Category: Cardiac MRI Toolkit

Module Description

This module automatically segments the left atrium from a cardiac LGE-MRI image volume. The input to the module is a cardiac LGE-MRI image, a smoothness parameter and model data. The model is arbitrarily selected and can be changed to check if it improves the segmentation output.

Usage

Examples, Use Cases & Tutorials

• This module is meant to be used for segmenting the left atrium from cardiac LGE-MRI images.

Quick Tour of Features and Use
