Breast Volume Measurement Using a Games Console Input Device

摘要

The automated measurement of breast volume has applications both in facilitating the decisions made by surgeons prior to breast reconstruction and in improving density estimation. We describe a novel approach to volume measurement for surgical planning, using a games console input device - the Microsoft Kinect. We have explored the ability of the device to measure surface depth for a range of distances and angles, demonstrating a mean depth error of below 1.5 mm for a distance range of interest (0.5 - 0.8 m). We have also validated the use of the system for volume measurement using a full-sized model female torso. The Kinect-based result is in good agreement with the volume measured by filling a mould of the breast with water (225.5±8.7ml, 229.4 ±9.7 ml respectively). The method has the potential to provide convenient, cost-and time-effective measurement of breast volume in clinical practice.
