Abstract

A system for monitoring displacements and/or rotational motion of in vivo objects is provided. The system comprises one or more magnetically coupled resonant electric circuits (RECs), a transmitter for exciting the pairs of RECs to oscillate, a receiver for receiving electromagnetic signals emitted by the oscillating RECs and a processor for deriving frequencies associated with the received signals. Each REC of a pair is respectively attached to an in vivo object, such as a segment of a bone. Relative translational and/or rotational motion of a pair of segments of a bone or bones result in varying resonance frequencies of the respective RECs. Monitoring is accomplished by comparing currently measured resonance frequencies with pre-stored frequencies. In a case in which variations in the measured frequencies do not exceed a predefined threshold a stationary state is determined.
