Comments about the differences between Slicer's semantics and that of other software:

Seems that Slicer's taxonomy of the entities that can comprise a scene can be confusing. We should try to at least define the concepts we use heavily somewhere.

  • A new user may not understand what a scene is.
  • An ROI is a general term in practice; Slicer uses it to mean an object that delimits the region.
  • What distinguishes a fiducial and a glyph.
  • and what distinguishes a glyph with a defined dimension (diameter for instance) and an ROI?
  • Is there a distinction between a manually defined painted region and predefined circle or sphere?
Slicer Terminology Suggested terminology
Volume ImageData
ROI(3D) Volume
ROI ROI (very general term -- could be pixel, pixels in slice, anatomic region, pixels in volume, set of pixels in multi-volumes)
Scene ? All data and its configuration
Label Labeled ROI
fiducial marker
Glyph marker-type
surface ?
Model ?
Volume rendering type of data display
Labelmap Labeled overlay
Overlay Parametric overlay
