Common Mistakes to Avoid
Common failures happen when the chosen tool is optimized for a different stage of the CT workflow than the one being executed.
Buying a viewer when the workflow requires automated registration and mask generation
RadiAnt DICOM Viewer supports fast viewing but it limits advanced CT analysis compared with full radiology platforms, which makes it a weak fit for radiotherapy-grade automation. Plastimatch and SimpleITK provide the command-line driven registration and segmentation pipelines needed for CT-to-mask workflows.
Choosing a segmentation tool that cannot meet the repeatability expectations
InVesalius supports interactive segmentation and ROI editing for CT-to-3D reconstruction, but large batch automation is limited compared with enterprise pipeline tools. 3D Slicer provides scripting and macros for repeatable CT processing pipelines, which supports consistent segmentation and analysis steps across cases.
Ignoring DICOM transport needs and assuming the viewer will solve ingestion
pydicom and the CT viewers focus on processing and visualization rather than end-to-end DICOM networking, so they do not replace archive integration. dcm4che provides Storage SCP and Query/Retrieve capabilities for CT image transfer, which is the correct foundation when integration is required.
Overbuilding a custom pipeline when a DICOM-ready image workflow tool already matches the job
pydicom is a Python API for dataset-level DICOM tag access and pixel data handling, and it does not provide a clinical-style CT visualization UI by itself.
