Patient positioning monitoring apparatus and method of use thereof

摘要

A patient position monitoring apparatus and method includes an article configured to be worn by a patient. The article includes a plurality of resonators with each resonator responsive to a wireless excitation signal for causing the unique change in the excitation signal or for outputting a unique wireless response signal. The resonators are stimulated with a first wireless excitation signal when the article is being worn by a patient. The unique change in the excitation signal and /or the unique response signal of each resonator responding to the first excitation signal is determined. From the thus detected response, a signal strength of the unique change in the excitation signal and/or the unique response signal for each responding resonator is determined. From the thus determined signal strengths, the relative locations of the responding resonators with respect to each other can be determined.
