Abstract

The small intestine is the longest part of the gastrointestinal (GI) tract, but it is difficult to examine with traditional endoscopic procedures. To resolve this, swallowable capsules have been created that slowly pass through the entire GI tract taking images. Research is currently being done in magnetic actuation and localization to increase the speed and control of these smart pills. This paper focuses on a technique to more efficiently control a capsule endoscope based on proprioceptive sensing of the magnetic field. This sensing provides knowledge of the applied field in the frame of the capsule, and enables determination of its current state.
用于磁胶囊内窥镜闭环控制的本体感觉磁场传感
小肠是胃肠道最长的部分,但很难用传统的内窥镜检查。为了解决这个问题,人们发明了一种可吞咽的胶囊,它可以缓慢地通过整个胃肠道拍摄图像。目前正在进行磁驱动和定位的研究,以提高这些智能药丸的速度和控制能力。本文研究了一种基于磁场本体感觉的胶囊内窥镜控制技术。这种感知提供了胶囊框架中应用领域的知识,并能够确定其当前状态。
