摘要

在本文中，我们评估了影响内窥镜无线胶囊在通过人体消化系统时定位精度的因素。利用三维全电磁波仿真模型，我们得到了胶囊在胃、小肠和大肠三个单独器官中的位置估计误差边界。仿真假设了两种不同的外部传感器阵列拓扑结构。我们比较了这些性能界限，并得出结论，对于不同的器官和外部传感器阵列的不同拓扑结构，位置估计误差是不同的。

Performance bounds for RF positioning of endoscopy camera capsules

In this paper, we evaluate the factors affecting the accuracy achievable in localization of an endoscopic wireless capsule as it passes through the digestive system of the human body. Using a three-dimension full electromagnetic wave simulation model, we obtain bounds on the capsule-location estimation errors when the capsule is in each of three individual organs: stomach, small intestine and large intestine. The simulations assume two different external sensor arrays topologies. We compare these performance bounds and draw the conclusion that location-estimation errors are different for different organs and for various topologies of the external sensor arrays.
