Module Description

The module filters the image to remove the intensity inhomogeneity due to the MRI image acquisition.

Usage

• Load the input dataset (Add Volume)
• Go to the menu Modules > Filtering > MRI Bias Field Correction
• Select the input dataset
• Modify the number of iterations (large values make the processing longer)
• Modify the fitting levels
• Click on Apply (processing of large images take in the order of minutes)
• Select the 'field' checkbox if you want to visualize the field
