Methods for locating a sensor element in vivo, e.g., during evaluation of tissue motion, such as of a cardiac tissue motion, e.g., heart wall motion, via electric tomography are provided. In the subject methods, an electric field is applied to a subject in a manner such that the sensing element is present in the applied electric field, and a property of, e.g., a change in, the applied electric field sensed by the sensing element is employed to evaluate a patient internal parameter of interest, e.g., to evaluate movement of tissue location, to evaluate a internal device parameter, such as movement thereof, etc. The invention allows for robust noise discrimination, e.g., by employing a spread spectrum applied electric field. Also provided are systems and devices for practicing the subject methods. In addition, innovative data displays and systems for producing the same are provided. The subject methods and devices find use in a variety of different applications, including cardiac resynchronization therapy. |
