APPARATUS AND METHOD FOR ESTIMATING SHAPE

摘要

An apparatus (480) for use in estimating the shape of a body part of a subject, which apparatus (480) comprises: a string of sensors (481) for positioning adjacent the body part so that the string of sensors substantially conforms with the shape of the body part, or at least a part of it, the string of sensors comprising at least one bend sensor and at least one stretch sensor (482) arranged end to end such that, in use, the at least one bend sensor lies adjacent a first region of the body part and the at least one stretch sensor (482) lies adjacent a second region of the body part, wherein the magnitude of a curvature of the first region of the body part is greater than the magnitude of a curvature of the second region of the body part.
