Project Description

Objective

• Define target DICOM types
• Define a good workflow to parse targets with DCMJS.
• Define required JS models to support the workflow.
• Evaluate DicomParser from cornerstone team.

Approach, Plan

• Talk with DICOM/DCMTK experts to get some feedback on best strategy.
• Write a demo to showcase js models and dicom parsing workflows.

Progress

• Evaluation of current solutions
  • yves:
    • pros: fast
    • cons: single frame and need to parse dicom header by hand in JS later on
  • dicomparser: same
  • dcmjs:
    • pro: relies on dcmtk, (almost) no need to manually parse dicom header by hand
    • cons: slower (150ms for dcmdump vs 30ms for other solutions)
  • note: compilation of dcmjs with -o3 or -of drasticly improves performance of dcmjs
• Proposed workflow
  • https://docs.google.com/drawings/d/1BX0NBIDPrrM-JGk9b1awL_w57f9rMvdTJSeVjT9bM5U
  • note: workflow relies on new dcmtk functionnalities. It will have to be evaluated in term of performance.
• Take dicom segmentations/models into account
• Testing database
