Paper Abstract

This paper describes a quantitative assessment of the Microsoft Kinect for X-box360TM for potential application in tracking respiratory and body motion in diagnostic imaging and external beam radiotherapy. However, the results can also be used in many other biomedical applications. We consider the performance of the Kinect in controlled conditions and find mm precision at depths of 0.8-1.5m. We also demonstrate the use of the Kinect for monitoring respiratory motion of the anterior surface. To improve the performance of respiratory monitoring, we fit a spline model of the chest surface through the depth data as a method of a marker-less monitoring of a respiratory motion. In addition, a comparison between the Kinect camera with and without zoom lens and a marker-based system was used to evaluate the accuracy of using the Kinect camera as a respiratory tracking system.
