Magnitude Weighting Mask

Magnitude Weighting Mask is a noise-suppression reconstruction technique that averages out the magnitude of the flow-direction scans. Every pixel in every image at a single location is averaged across the magnitude of the whole slice to smooth out the image background.

• Unless you specifically want to view a non-averaged image, keep Magnitude Weighting Mask = On (1) for all Fast 2D Phase Contrast acquisitions.
• If the mask is turned off, you will see very extreme pixel values on the image outside the flow.
