Current method
Measure at a few points.
Tape measurements at selected points are used to estimate volume with a simplified geometric model.

Measure limb
volume in 3D.
LimbVolScanner is being developed to capture a limb’s shape
with an iPhone and calculate volume from a 3D model.
Development prototype. Not CE-marked; not available for clinical use.
- Runs on iPhone
- 3D limb capture
- Guided workflow
- Digital volume tracking
Designed for clinical evaluation
Exploring smartphone-based limb-volume measurement
for research into lipedema and lymphedema.
Clinical input: Dr. med. Jeremias Schmidt Senior physician, Plastic and Aesthetic Surgery Helios Klinikum Berlin-Buch, Berlin
Why 3D measurement?
Measure the shape itself.
With LimbVolScanner
Capture the whole shape.
Scan the leg from thigh to ankle. The app captures its surface in 3D and calculates volume from that shape.
Volume from the captured 3D surface
How it works
Scan. Review. Track.
The planned workflow creates a 3D model and calculates the leg’s volume.
-
1
Scan the leg
Move the iPhone around the leg, from thigh to ankle. Follow the on-screen guidance.
-
2
Review the volume
See the 3D model and calculated volume, then save the measurement.
-
3
Track changes
Compare with earlier scans to follow volume changes between visits.

Areas for evaluation
Track volume over time.
We aim to explore how 3D measurements could help track limb-volume changes. Clinical validation results are not yet available on this website.
- Lymphedema
- Lipedema
- Pre- and post-
treatment measurements - Long-term

Validation
Performance validation is pending.
Accuracy and repeatability need to be established through appropriate validation. This website presents the measurement concept and illustrative screens; it does not provide a tool for diagnosis or treatment decisions.
