Wireless magnetic motion capture system for medical use

The estimation of organic functions in the human body is important for both diagnosis and treatment in the medical field. In order to adequately assess these functions, a detection technique having an accuracy of better than 1 mm is required for body motion analysis. A wireless magnetic motion capture system is one such effective detection technique. Recently, the development of a new motion capture system using an LC resonant magnetic marker (LC marker) has been reported. This new system consists of both driving and pickup coils as well as small LC markers that do not have batteries or electric wires that may interfere with natural organic functions. It is suggested that this system is reliable and effective for diagnosis and treatment in the medical field, because it is a noninvasive system with six degrees of freedom that is able to capture magnetic markers in the human body.
