Abstract:
A method of obtaining a signal from a measurement system which corresponds to values of area or volume of at least one object within a homogeneous magnetic field, comprising the steps of:a. configuring conductive coil means tightly about the various circumferences of at least one portion of an object; b. positioning fixed coil means remotely to the conductive coil means so that a homogeneous magnetic field is created around the conductive coil means in the case of the fixed coil means carrying an electrical current or said magnetic field being created around said fixed coil means in the case of said conductive coil means carrying said electrical current; and c. generating a constant electrical current into either the conductive coil means or the fixed coil means to create an induced voltage signal in the other coil means, said constant current substantially increasing the accuracy of said measurement system.
