Adding a mask to hide or enhance volume structuresTopic number: 1509394407694

When you add a mask you can select a tool to use to create the mask and you can specify the appearance of the mask.

Prerequisite

The volume segmentation tools are available only when at least one volumetric series with a built volume is present in the current presentation group. This can be achieved, for example, by selecting a MPR hanging protocol, or by switching the render type of one of the given viewports to MPR or 3D.

To add a mask to hide or enhance volume structures
  1. On a CT volume dataset, in the Clinical sidebar, click Volume segmentation. Volume segmentation
