Common Mistakes to Avoid
Several consistent pitfalls show up across the tools when teams mismatch capabilities to their workflow needs.
Choosing a basic viewer when synchronized MPR and cross-panel navigation are required
Tools like MicroDicom focus on fast 2D navigation and windowing, so they are not ideal for teams that need synchronized multi-planar inspection across panels. OsiriX, Horos, Weasis, and OHIF Viewer all prioritize synchronized multi-planar reconstruction or linked crosshair workflows for volumetric review.
Expecting advanced segmentation and quantitative analysis from a viewing-only workflow
RadiAnt DICOM Viewer and Sante DICOM Viewer focus on local viewing, windowing, navigation, and measurements, and advanced segmentation is not their core strength. 3D Slicer provides segmentation, registration, and quantitative analysis modules with scriptable segmentation workflows.
Underestimating the setup and dependency burden of web viewers
OHIF Viewer relies on external configuration and backend services for web-based DICOM viewing, which affects deployment planning. Orthanc Viewer also depends on running and tuning an Orthanc server to provide REST-backed browsing, so infrastructure work is part of the rollout.
Ignoring how collaboration and team-wide review features are positioned
RadiAnt DICOM Viewer, MicroDicom, and Horos emphasize local workstation workflows rather than deep collaboration and remote PACS-style features. OHIF Viewer and Orthanc Viewer can support shared workflows through web viewing, but enterprise PACS report tooling and worklists are not the primary scope across the reviewed tools.
