Private, local-first upload
Drop a DICOM ZIP or a NIfTI file. Series are inspected and optionally anonymized in your browser before anything is sent.
CT segmentation workspace
From CT upload to editable 3D segmentation in minutes.
TotalSegmentator Studio runs TotalSegmentator on your CT series and opens the results in a web viewer with synchronized MPR, 3D surfaces and mask editing — no installation needed.
TotalSegmentator modules
Run the Default module (117 structures) or the Lung module (airways, vessels, lobes, nodules) on the series you choose.
MPR + 3D viewer
Axial, sagittal and coronal views with linked crosshairs next to an interactive 3D rendering of all masks.
Edit masks
Brush and erase in 2D or 3D, with HU thresholds. Edits are saved with one click and the original automatic result stays available.
Airway subtree segments
Click a bronchus in 3D to colour its distal subtree and get the matching lung segment computed instantly.
Binary & multilabel NIfTI
Images and segmentations are stored as NIfTI, so results stay portable and can be downloaded at any time.
Modules
Each module picks its TotalSegmentator tasks, tools and default viewer layout.
Default
Whole-body anatomy
The TotalSegmentator “total” task with 117 classes: organs, bones, muscles and vessels.
- 2×2 layout: axial, sagittal, coronal, 3D
- Brush, eraser, measurements, W/L presets
Lung
Airways, vessels & lobes
Airways, pulmonary arteries and veins, lung lobes, nodules and carcinoma.
- Pick an airway subtree in 3D, adjust its depth
- Live lung segment for the picked subtree
How it works
- UploadChoose a DICOM ZIP or NIfTI. Pick the series and decide whether to anonymize.
- ConvertThe study appears in your list right away while it is converted to NIfTI.
- ProcessStart the Default or Lung module on the series you want; progress is shown live.
- Review & editOpen the result in the viewer, inspect in MPR and 3D, and refine the masks.
