Rotary Joint Data Transmission for CT Scanners

The patent combines video data transmission and control data transmission into a single broadband data path. The transmission controller multiplexes both data types onto one communication channel, eliminating the need for separate transmission technologies while maintaining reliable transmission of both data types through structured data frames with appropriate timing and synchronization.

The broadband data path is designed to serve multiple functions: it transmits both high-speed video data and control/monitor data simultaneously. The transmission controller and reception controller work together to handle different data types through a single interface, making the system more versatile and reducing the number of dedicated components needed.

The system uses periodic timing signals and structured data frames to convey additional information. Control data is transmitted at defined positions within the video data stream, using timing-based synchronization rather than separate signaling lines. This allows conventional parallel-serial converters to maintain their simplicity while the system gains enhanced communication capabilities through intelligent data framing and timing.

The transmission controller acts as an intermediary that embeds control information within the video data stream using structured framing. Rather than requiring additional signaling hardware, the controller mediates between the simple converter and the need for complex communication by encoding control signals in the data structure itself, enabling versatile signal communication through conventional hardware.
