Project Description

Objective

Continue development of pure-javascript dicom utilities for manipulating data in web applications.
Integrate visualization and display elements.
Create utilities that perform useful work.

This project also covers a grab bag of backlog issues related to segmentation and structured reporting in DCMJS, Cornerstone, and the OHIF Viewer packages.

Some potential goals for this Project Week are:

Create lightweight single-page segment editor prototype for loading / editing / resaving DICOM Segmentations with DCMJS & Cornerstone
Improve performance of loaded DICOM Segmentation files by implementing proposed non-overlapping segment flag support
Add missing WebGL rendering paths for label maps and false color images in Cornerstone Core
Mock up & implement UI for DICOM Segmentation display in OHIF Viewer
Research potential DICOM SR templates for storage and retrieval of annotations for OHIF Viewer (e.g. length tool, etc…)
Check what is still missing to support image segmentation use cases for Tobias Penzkofer (Charité Universitätsmedizin, Berlin) & Felix Nensa (University Hospital Essen)
Add documentation to Cornerstone Tools Documentation for segmentation tools
Add display support for fractional segmentation maps to WADO Image Loader

Approach and Plan

Brainstorm to define useful utilities, such as client-side deidentification, data organization, previewing, format conversion, online markup or segmentation tool…
Experiment with DICOMweb APIs
Design, implement, and test prototypes
Get community feedback

Progress and Next Steps

Discussed DICOMweb prototype with cornerstone
IHEInvokeImageDisplay demonstration launched from dcm4chee
ProstateX data loaded in dcm4chee and launchable at Patient level to display all series
Next Step: integrate with PI-RADS project progress
