Project Description

The project is about desktop integration infrastucture for healthcare applications. It introduces a new 3D Slicer extension that provides backend and front-end services to that effect.

The extension repository is here: https://github.com/mbellehumeur/SlicerCastInterface

Objective

• Proof of concept global scene views to circle back to PW43 AI for personal hanging protocols project.
• Demonstrate the new 3D Slicer extension with a worklist example application.
• Demonstrate medical imaging resource server integration with the research of NA-MIC conference participants

Approach and Plan

• Implement resource servers concept.
• Implement SCENEVIEW request in the Slicer image display client
• Implement cast interface in Slim

Progress and Next Steps

Three project week teams integrated their research:

• Lung cancer screening with OHIF (https://projectweek.na-mic.org/PW45_2026_Boston/Projects/ExtractingDeepLearningFeaturesFromCtImagesOfTheThoracicRegionForLungCancerApplications/)
• Subcortical segmentation: with VolView. (https://projectweek.na-mic.org/PW45_2026_Boston/Projects/Vox2SeglamProtocolGuidedSubcorticalSegmentationIn3DSlicer/)
• AI search agents for IDC data with the worklist example application. (https://projectweek.na-mic.org/PW45_2026_Boston/Projects/RedesignedRestApiAndMcpServerForImagingDataCommons/)
