Abstract

Through a wireless capsule endoscope (WCE) fitted with a miniature camera (about an inch), this study aims to examine the role of wireless capsule endoscopy (WCE) in the diagnosis, monitoring, and evaluation of GI (gastrointestinal) disorders. In a wearable belt recorder, a capsule travels through the digestive tract and takes pictures. It attempts to find tiny components that can be used to enhance the WCE. To accomplish this, we followed the steps below: Researching current capsule endoscopy through databases, designing and simulating the device using computers, implanting the system and finding tiny components compatible with capsule size, testing the system and eliminating noise and other problems, and analyzing the results. In the present study, it was shown that a spherical WCE shaper and a smaller WCE with a size of 13.5 diameter, a high resolution, and a high frame rate (8-32 fps) could help patients with pains due to the traditional capsules and provide more accurate pictures as well as prolong the battery life. In addition, the capsule can also be used to reconstruct 3D images. Simulation experiments showed that spherical endoscopic devices are more advantageous than commercial capsule-shaped endoscopic devices for wireless applications. We found that the sphere's velocity through the fluid was greater than the capsule's.

摘要

通过一个装有微型摄像头（约一英寸）的无线胶囊内窥镜（WCE），本研究旨在探讨无线胶囊内窥镜在胃肠道（GI）疾病的诊断、监测和评估中的作用。在一个可穿戴式腰带记录仪中，一个胶囊穿过消化道并拍照。它试图找到可用于改进WCE的微小部件。为实现这一目标，我们采取了以下步骤：通过数据库研究当前的胶囊内窥镜，使用计算机设计和模拟该设备，植入系统并找到与胶囊尺寸兼容的微小部件，测试系统并消除噪声和其他问题，以及分析结果。在本研究中，结果表明，一个球形WCE成型器以及一个直径为13.5、具有高分辨率和高帧率（8 - 32帧/秒）的较小WCE，可以帮助因传统胶囊而感到疼痛的患者，提供更准确的图像并延长电池寿命。此外，该胶囊还可用于重建3D图像。模拟实验表明，对于无线应用而言，球形内窥镜设备比商用胶囊形内窥镜设备更具优势。我们发现球体在流体中的速度大于胶囊的速度。
