Back to Slicer3 UI Design

Slice viewing can operate in the context of a single slice reformation or in a linked state where multiple slice viewers respond to interactions with any slice viewer. When Slice Viewers are linked, a number of viewing geometry, view representation and view content parameters are linked across viewers.

  1. Proposals for linked controls behavior in Slicer4.
  2. 2.0 2.1 Just propagated to compare viewers. Red Slice not included.
  3. 3.0 3.1 3.2 3.3 When linked, only one reformat widget is displayed. When unlinked, it is possible to show multiple reformat widgets.This might not be desirable.
  4. 4.00 4.01 4.02 4.03 4.04 4.05 4.06 4.07 4.08 4.09 4.10 4.11 4.12 4.13 4.14 Viewers with same reformation linked.
  5. 5.0 5.1 5.2 5.3 Axial, sagittal, coronal should remain orthogonal.

Notes

  • Not all keyboard controls have been captured in this table.
  • Many controls will not illustrate the linked behavior until the interaction completes (translate, zoom, slice offset).
