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 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).
