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. Model data to run this module can be downloaded from the Slicer Midas repository.

Use Cases

This module can be used to automatically segment the Left Atrium from a cardiac LGE-MRI image.
