Fig 5:

Flowchart outlining the steps (i - vi) in the artifact region segmentation algorithm using the residual water suppression imaging maps (rWSI) acquired in vivo. After filtering and thresholding, images are eroded and segmented into separate regions using the watershed transform. This process is repeated until the number of estimated regions, N, is less than or equal to 8. Intermediate steps are shown using an example transverse slice (R02). In practice, the image processing steps are applied to the 3 dimensional image data.
