论文摘要
无线胶囊内窥镜检查（WCE）已被广泛用作辅助传统有线胃镜检查的补充，尤其是对于超出后者范围的小肠疾病。但是，由于无线数据速率有限，视频分辨率和帧速率都受到当前WCE解决方案的限制。其背后的原因是，与空气相比，WCE使用的电磁（EM），基于射频（RF）的通信方案严格限制了可用的带宽和功率，并且人体的衰减很大。超声通信可能是一种潜在的替代解决方案，因为它可以访问更高的带宽和传输功率，并且衰减较低。在本文中，我们提出了一种超声通信方案，专门设计用于通过组织数据传输来高数据速率，并通过成功传输超高定义（UHD）视频（3840*2160像素为60 fps）到5厘米的猪肚来验证这种通信方案。通过提出的通信方案和我们定制的基于基于我们定制的现场可编程门阵列（FPGA）测试平台，实现了超过8.3 Mbps错误的有效载荷数据率。
Wireless capsule endoscopy (WCE) has been widely adopted as complementary to traditional wired gastroendoscopy, especially for small bowel diseases which are beyond the latter's reach. However, both the video resolution and frame rates are limited in current WCE solutions due to the limited wireless data rate. The reasons behind this are that the electromagnetic (EM), radio frequency (RF) based communication scheme used by WCE has strict limits on useable bandwidth and power, and the high attenuation in the human body compared to air. Ultrasound communication could be a potential alternative solution as it has access to much higher bandwidths and transmitted power with much lower attenuation. In this paper, we propose an ultrasound communication scheme specially designed for high data rate through tissue data transmission and validate this communication scheme by successfully transmitting ultra-high-definition (UHD) video (3840*2160 pixels at 60 FPS) through 5 cm of pork belly. Over 8.3 Mbps error free payload data rate was achieved with the proposed communication scheme and our custom-built field programmable gate array (FPGA) based test platform.
