The Structures tab is where you go to see the list of contoured anatomical structures and to control their display. The Structures tab allows you to do the following:

  • View structure names in the active structure set
  • View structure colors
  • Toggle structure display on/off, individually or en masse
  • Toggle image and dose layers on/off (useful while contouring)

The Structures tab is also where you will go to do contouring (i.e., to create new, or edit existing, anatomy contours). Please refer to the dedicated “Contouring” category to learn about those features.
