Project Description

Cast interface Module for 3D Slicer: Resource Servers, Image Display client and Hub.

Resource servers: Resource servers subscribe to all user topics for dicom/nifti events and send back results to the user throuh the hub. Each server has its own onMessage script. The script handles producing the results from the DICOM files received and publishes a dicom-send event back to the user topic.

Image Display Client: The image display client provide a PACS client type interface to the 3D slicer viewer. Supported events should be ImagingStudy-open, Imaging-Study-close, dicom-send and request for sceneview.

Hub: The hub is the server that distributes the messages and handles the data transfer requests over the websocket connection to each client.

Objective

• Develop standard desktop integration of AI resources like Total Segmentator.
• Finish the request for SCENEVIEW started in project week 44 by adding an image display client to the 3D slicer viewer.
• Support 3D Slicer developers who want to connect to cast / FHIRcast.

Approach and Plan

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