System and Method for Determining Medical Capsule Location inside a Human Body

摘要

Systems and methods are provided for capsule location determination. There is a need to estimate the capsule location in a living body for drug dispensing, correlating capsule images with actual tract location and other purposes. A capsule location determining system is disclosed which comprises a plurality of sensing devices and a base station. Each sensing device comprises a radiating element to radiate an inducing signal, a generating circuit to provide a patterned signal to drive the radiating element, a sensing element to sense the induced field and a receiving circuit to provide a recovered signal. The base station estimates the capsule location based on a time profile of collected information related to the recovered signals from all sensing devices. Methods associated with the capsule location determining systems are also disclosed.
