本文提出了一种4摄像头VGA分辨率胶囊内窥镜系统，采用80Mb/s体信道通信收发器和亚厘米范围定位技术，解决了传统单摄像头胶囊内窥镜视角不足、盲区导致漏诊率高达20%的问题，实现了360°全视角成像。
alternative to the cable-attached endoscopes since not only mitigating pain and fear of patients but also acquiring additional information about unexplained lesions for accurate diagnoses. Nevertheless, their applicability has been mainly limited by insufficient viewing angles and image qualities [1]. Especially, a single end-facing camera with VGA resolution images suffers from blurred and blind zone through digestive canal, increasing its overall miss-rate up to 20%, which is fatal in diagnosis [2]. A 4camera capsule was proposed to support 360°- visual angle [1], however, full 360° images were just stored on a Flash EPROM without wireless image transmission, real-time image viewing and capsule tracking. Full 360° high resolution images with multi-cameras inherently require high data-rate wireless
