Demo of wireless HD-video transfer from inside a human-body-phantom to an on-body receiver

This video demostrates wireless HD video transmission from a capsule placed inside a liquid human-body-phantom to a receiver located outside of this phantom. We show and discuss how different parameters affect link quality.
We designed the antenna system as well as the test setup, in order to enable transmitting HD video data from a capsule embedded inside the the human body, wirelessly to a receiver placed outside the body. The wireless link in this test setup is realised with software-defined-radios handling the video transmission and reception, and especially designed antennas for the capsule transmitter and for the on-body receiver. The target application is wireless gastroendoscopy, i.e. medical applications that require high-resolution video images from inside the gastrointestinal tract of a patient. We hence demonstrate one promising practical implementation of an antenna system that enables very high data rates needed to ensure HD video transmission.

本视频展示了将置于液态人体体模（liquid human-body-phantom）内部的胶囊端所采集的高清视频，无线传输至该体模外部接收器的过程，并探讨了各类参数对链路质量的影响。为达成将嵌入人体内部的胶囊所采集的高清视频数据，经无线链路传输至体外接收器的目标，我们设计了专用天线系统与测试搭建方案。本次测试中的无线链路，由负责视频收发的软件定义无线电（software-defined-radios），以及为胶囊发射端与体表接收端定制的天线共同实现。本方案的目标应用场景为无线胃镜检查，即获取患者胃肠道内部高分辨率视频图像的医疗应用。据此，我们展示了一种极具实用前景的天线系统实现方案，该系统可提供保障高清视频传输所需的超高数据速率。
