2024.10.15 Weekly Meeting

Meeting Notes

Terminologies

  • Module Improvements: Discussed potential enhancements to the Terminologies module. See the discussion here: Slicer Issue #6975.

  • Terminology, Color Table, and Segment Relationship:

    • There is a significant disparity between the vast number of available terminology terms and the limited number of segments. The color table serves as a bridge:
      • Analogy: Terminology represents all available paint colors, the color table is the palette, and segments are the canvas.
  • Handling Missing Terms:

    • It is not problematic if a segment lacks a corresponding term in the terminology. A streamlined editing approach could involve direct color table modifications. This would require an improved file format for color tables (details below).
    • Idea: Develop a new Terminologies extension to connect with an online repository of terminologies (e.g., on GitHub).
  • Color Table File Format Enhancements:

    • Transition to CSV format, ensuring compatibility with scene load and save operations.
    • Include all essential terminology information: name, code, coding scheme designator, category, modifier, and optional anatomical location.
    • Allow for JSON properties to be optional, omitting unused entries.
  • Displaying Color Tables in Terminology Contexts:

    • Limit to discrete options and filter based on specific attributes (e.g., “compatible”: adequate metadata).
  • Creating a “Short List” Color Table:

    • Enable users to generate a new color table based on current segments, providing a customizable starting point.
  • MorphoDepo (MorphoCloud) Requirements:

  • Using Uberon in Terminologies:

    • Hierarchical structure required, such as categories (e.g., “skeletal system / spine”) to create a more organized tree structure, replacing the current flat list.
  • Next Steps:

    • Enhance color tables to store metadata effectively.
    • Integrate color tables within the terminology selector for streamlined user experience.

Slicer & Trame

  • Trame Integration:
    • Discussed the integration of trame with Slicer to support backend GPU rendering.

    • Render window content is converted into a compressed JPEG image, which is transmitted to the front end as a web application.

    • Transitioning to in-render window widgets would minimize dependencies on Qt.

    • Refactoring will be required to enable segmentation editor effects to function independently from Qt.

    • Progress related to Slicer refactoring is ongoing; see Commits · AlexyPellegrini/Slicer · GitHub

    • On-going development of trame-based Slicer should be released open-source in the first quarter of 2025. For questions, reach out to @finetjul, @Thibault_Pelletier and @jcfr

Telemetry

Slicer 5.8 Release

  • The release status of version 5.8 will be discussed in the upcoming meeting on October 22nd.
