General Information

Module Type & Category

Type: CLI

Category: CARMA

Module Description

This module implements a local intensity correction for inhomogeneities due to coil placement in cardiac LGE-MRI images. It fits a gradient function to the image data and normalizes accordingly. Note that this is not a whole image correction and it is specific to LGE MRI cardiac images. The input to this module is a segmented region on which to base the intensity gradient model and a segmentation of the region of interest to apply the correction. There are no parameters.

Usage

Examples, Use Cases & Tutorials

• This module is meant to be used for MRI scans where local inhomogeneity has been detected
