Annotation Module in Slicer4

Key Investigators

• BWH: Nicole Aucoin
• UPenn: Daniel Haehn, Kilian Pohl
• Isomics, Inc.: Alex Yarmakovich
• Kitware: Will Schroeder

Objective

Improve usability of the Annotation module in Slicer4 through bug fixing and UI re-working.

Approach, Plan

• Fix text annotation issues (font, scale, positioning)
• Fix ruler text issues (font, scale)
• Redesign property editor
• Fix moving/dropping widgets

Progress

• Added a default hierarchy list node when adding annotaitons, so by default each type is grouped together. This makes it easier to select a list of fiducials from a node selector.
  • used a mrml node attribute to record the class name of the annotation type used for each hierarchy (not enforced if drag and drop displayable nodes via the tree views)
  • renamed the top level hieararchy node to "Main Hierarchy"
• Had discussions on the hierarchy design to improve drag and drop
• Collected user feedback in a breakout session
• Made Fiducials transformable
• Activated PythonQt wrapping for the Annotation widgets: the ROI widget can now be used in Python modules
• Breakout session
