Volume Measurement of the Leg by Using Kinect Fusion for Quantitative Evalu- ation of Edema

抄録

In this paper, we propose to evaluate the edema of a leg by volume measurement using Microsoft Kinect. The volume is calculated from a measured point cloud by our improved voxelization technique. Additionally, the depth camera of Microsoft Kinect is feasible for use in home care systems due to its very low cost compared with other depth cameras. In an experiment, we measured the leg volumes of three healthy subjects in the morning and evening for three days. For each subject, the mean volume values were obtained from five measured values. The increase of volume was confirmed in all experiments from morning to evening. These experimental results meet the physiological expectation. Because the changes in leg volumes are greater for a patient with serious edema than for a healthy person, we conclude that the proposed system can appropriately evaluate leg edema.
