一种人体移动对胶囊内窥镜磁定位干扰的补偿方法
A Compensation Method for Magnetic Localization on the Capsule Endoscope about the Interference of Body Movement
摘要
Abstract
Magnetic localization technology can achieve high accuracy in capsule endoscope positioning and track⁃ing. There is a magnetic in the capsule endoscope,so can install magnetic sensor array around the human body to measure the magnetic intensity. Then,the computer can get the data from the circuit processing and applied the po⁃sitioning algorithms to calculate the position and direction of endoscope in human body. However,there is a prob⁃lem in this method:In the process of physical examination with capsule endoscope,the movements of human body will interference the accuracy of positioning to endoscope. In order to compensate this human body motion interfer⁃ence,we propose a method that set two magnets as the reference targets outside the human body,and the two mag⁃nets are perpendicular to each other. Then applied the specific positioning algorithm to reduce the interference which caused by the movement and rotation of human body. Finally,we verify the feasibility and effectiveness of the proposed method through experiments.关键词
