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
- 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.
- https://github.com/andywer/threadpool-js
- Take dicom segmentations/models into account
- DICOM testing database discussion with web-torrents
Benchmark
Benchmark of DICOM parser libraries using benchmark.js (what-do-the-results-from-benchmark-js-mean).
These results were obtained on a Lenovo Flex2 laptop (Intel Core i3-4030U) under Microsoft Windows 8.1 using Mozilla Firefox (ff) 38.0.5 and Google Chrome v43.0.
Parsers: dcmjs (3fe78dd), dicomParser (v1.0.2) and dwv (v0.10.0). The test just calls the parse method of each library, no values are checked. Note that the 'dicomParser' does not interpret the data until asked for when the others do at parsing time.
Units are in operations/seconds.
