New Feature: visual DICOM browser

Description

The visual DICOM browser provides a new user interface for quick viewing and retrieval of patient images stored on remote DICOM servers. The new tool is optimized for clinical workflows where the focus is on all the images of a single patient - as opposed to the existing DICOM browsing experience, which was more suitable for bringing together images from many patients.

Both server and local content at the same place and are visualized by thumbnails. All data is retrieved in the background using classic DIMSE networking (most commonly used protocols in hospitals), in multiple concurrently running threads. The currently supported operations are:

  • Browsing and filtering with thumbnails of content of local DICOM database and multiple remote DICOM servers.
  • Query/Retrieve data from servers (DIMSE C-FIND, C-GET, C-MOVE SCU). All the operations are done in background and in parallel. Downloaded data is automatically cached in the local DICOM database. A unique feature is the possibility to retrieve images using C-GET protocol (suitable for cases when many Slicer instances are running in docker containers) with a clinical PACS that only supports C-MOVE protocol (most clinical PACS), via a proxy server (such as the free Orthanc).
  • Import data from local files.
  • Receive data sent from remote PACS (DIMSE C-STORE SCP).
  • Send data to remote PACS (DIMSE C-STORE SCU).
  • Quick browsing of all DICOM metadata and pixel data.
  • Remove data from local database (not from server).

Feedback

We have tested the widget mostly on Linux and Windows on multiple servers (Orthanc, www.dicomserver.co.uk, and some clinical PACS). It would be great to get feedback how the browser performs in different environments.

Developement is still ongoing, and a comprehensive roadmap is available here. We are looking forward to receiving error reports or any comments and suggestions for further improvements.
