Recently, the capsule detection for examination of gastrointestinal (GI) tract became a novel noninvasive system, but it was still a problem for capsule’s location.This paper examined various technologies used for measuring position based on magnetic method of the capsule in GI tract, while some new methods were investigated and their efficiency and complexity were analyzed.The results show that the radio frequency location is only practicable, but the tri-coil stimulating magnetic method and magnetic marker method can help to acquire a high precise, simplified, efficient and localized device.
