Noise Filtering Methods in MRI - Advance Image Processing in Magnetic Resonance Imaging - page 178

Typical line profiles extracted from the phantom image before filtering (thin line) and

after filtering (bold line) are shown in Figure 6.7 , showing the filter's ability to preserve

edges while removing noise.
In cardiac images, anisotropic filtering still preserves contrast at the myo-
cardium interfaces: it clearly appears in 1 NEX image aquisition as shown in

Figure 6.8 . The relevant line profiles before (thin line) and after anisotropic

filtering (bold line) are shown.
Such results are important for the later segmentation operation by an auto-
matic procedure.
