Abstract:
1. A system for measuring volume, the system comprising: an electromagnet configured to produce a magnetic field; a conductor configured to cover a portion of a subject for which a volumetric measurement is desired, the conductor configured to extend only once around the subject in a first direction and having a width generally perpendicular to the first direction, wherein upon placement of the conductor in the magnetic field the conductor is configured to produce a signal representing an average cross-sectional area, averaged over the width of the conductor, of the portion of the subject, wherein the conductor comprises segments forming a zigzag pattern extending in the first direction, and wherein the width of the conductor is delineated by a top and a bottom of the segments; and a control system configured to determine a volume of the portion of the subject based on the signal produced by the conductor.
