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.

本视频展示了液体人体模体（liquid human-body phantom）内部胶囊的高清视频无线传输过程，信号将传输至该模体外部的接收机。我们展示并分析了不同参数对链路质量的影响。为实现嵌入人体内部的胶囊向体外接收机的高清视频无线传输，我们自主设计了天线系统与测试搭建方案。本次测试搭建中的无线链路采用软件定义无线电（software-defined-radios）完成视频的收发，并使用专门为胶囊发射机与体表接收机设计的天线实现信号传输。本测试的目标应用为无线胃镜检查（wireless gastroendoscopy），即获取患者胃肠道内部高分辨率视频图像的医疗应用场景。因此，本演示验证了一款可满足高清视频传输所需超高速数据速率的天线系统的实用可行性。
