A 3D Tablet Sensor Approach to the Measurement of a Lymphedema

Not Applicable

Completed

• Conditions: Lymphedema

• Registration Number: NCT04821440
• Lead Sponsor: University Hospital, Brest

Brief Summary

Up to now, the diagnosis of lymphedema remains hard and delayed. It suffers from many limitations such as lack of coordination and formation of the health-care network. The diversity of used tools is another obstacle because all provided solutions on the market are either costless with poor accuracy, or highly expensive but with excellent accuracy. Therefore, we decided to evaluate an affordable and open-source 3D iPad sensor sharing the same technology used in Kinect sensors.
