3.2 Edge, smoothing and lung enhancement filters
The edge and smoothing filters enhance anatomical structure without additional reconstruction
time.
Edge Enhancement filters sharpen the image and are useful for filming bone windows. There
are six levels of Edge Enhancement: E1, E2, E21, E22, E23 and E3. E1 applies the least
amount of enhancement and E3 applies the most. When these filters are used, the image is
annotated with E1, E2, E21, E22, E23 or E3.
The smoothing filters decrease the appearance of noisy images or enhance low-contrast areas
when filming soft tissue. There are five Smoothing filters, S1, S11, S2, S22 and S3. S1 applies
the least amount of smoothing and S3 applies the most. When these filters are used, the
images is annotated with S1, S11, S2, S22, or S3.
The Lung Enhancement filter is designed specifically to use when filming lung windows. When
the Lung Enhancement filter is applied, the image is annotated with the word Lung.
