3.3 Gray Scale Enhancement
Gray Scale Enhancement (GSE) changes the slope and gamma curve of an image. It can be
used in head studies to improve the bone/brain interface, which helps with gray/white matter
differentiation. There are three levels of GSE: G1, G2, and G3. G1 applies the least amount of
enhancement and G3 applies the most. The GSE filter selected is applied to all images in the
series. When you apply this filter, the image is annotated with G1, G2, or G3 just above the
vertical tick mark scale on the right side of the image.
