The invention relates to a capacitive coupling type slip ring and a CT (Computed Tomography) detection device, belongs to the technical field of an X-ray computed tomography imaging technology ('CT technology 'for short), and solves the problems in the prior art that the size of equipment is increased and the cost is high due to the fact that the communication rate of the whole system is increased by increasing the width of a rotating disk. The capacitive coupling type slip ring comprises a disc body, a sending unit and a receiving unit, wherein the sending unit comprises a sending antenna and a sending end data processing unit; and an antenna is circumferentially arranged on the inner surface of the tray body. According to the invention, multi-channel data transmission is realized. 本发明涉及一种电容耦合式滑环及CT检测装置，属于X射线计算机断层扫描成像技术(简称"CT技术")技术领域，解决了现有技术中通过增宽旋转盘的宽度来提高整个系统的通信速率，导致设备体积增大，并且成本高的问题。该电容耦合式滑环包括盘体、发送单元和接收单元，所述发送单元包括发送天线和发送端数据处理单元；所述盘体的内表面设有周向设置的天线。本发明实现了多通道数据传输。
