Summary

Volumetry is essential for the diagnosis and follow-up of patients with limb edema. The objective of this project is the validation of real-time reconstruction and calculation of limb volume using a 3D laser scanner.

Water - displacement volumetry (water-filled boot) is the reference method with known accuracy and reproducibility, but is not commonly used in clinical practice because it is cumbersome, difficult, and time-consuming. The most commonly used method remains segmental limb perimetry with a tape measure, followed by volume calculation using the truncated cones formula, thus excluding de facts extremities (hands and feet) which can neither be likened to cones nor easily measured.

Quantification limb volume and volume changes is essential for the diagnosis and follow-up of patients with chronic venous insufficiency or lymphedema, two very common pathological conditions. It is mandatory for the evaluation of therapeutic approaches.

The present study will use an innovative technology of volume acquisition by freehand laser scanning with a hand-held camera with Quantification limb volume and volume changes is essential for the diagnosis and follow-up of patients with chronic venous insufficiency or lymphedema, two very common pathological conditions. It is mandatory for the evaluation of therapeutic approaches.

The present study will use an innovative technology of volume acquisition by freehand laser scanning with a hand-held camera with real-time 3D reconstruction.

Its advantages are non-contact, accurate and detailed quantification of edema, including extremities, allowing to assess the magnitude and topography of physiological, pathological, or treatment - induced volume changes. This approach will ultimately provide data that will used for designing personalized limb compression ortheses.
