The progression tool is similar to the snap-to tools with the additional feature that it splits the image into equal size segments such that each pixel exists in a single segment. The user can then progress through each segment, thereby displayed the full image without any duplication of data.
The view progression tools require a mammography plug-in module license. Built-in accelerator keys exist for advancing to the next and previous segments.

When in progression mode, the progression mode icon appears in the top left corner of the image frame. Progression mode remains active until the user advances past the last segment, exits using the menu option, or loads an image into the image frame.
A border appears around the unique data in each segment. The data displayed behind the border is data from the neighboring segment. The size of the border is defined by the Progression Overlap setting.
If skin line was applied to the image during the viewer session, the progression mode segmentation is based on the anatomical structure, regardless of the current application of skin line on the image. If skin line was never applied, the segmentation is performed on the entire image.
When progression mode is active in an image frame, cine playback is disabled.
