X-ray ct apparatus and medical data communication link system

An X-ray CT apparatus equipped with a data communication link system that intermediumtes data communication between a rotating frame and a stationary frame comprising:

• an X-ray tube provided at said rotating frame to radiate X-rays;
• an X-ray detector provided at said rotating frame to detect the X-rays transmitted onto an object;
• a signal generation device provided at said rotating frame to divide the data output by said X-ray detector into N channels for output;
• a transmission medium of 2N components provided separately in a line along the circumference of said rotating frame, any of which have the same line shape and length of one transmission line;
• a switching device provided to said rotating frame to assign said N channels to each transmission medium upon receipt of each data divided into N channels from said signal generation device;
• and
• a receiving medium of N components provided to said stationary frame located along the circumference of said rotating frame that receives data by charge-coupling or electromagnetic coupling, wherein
• said switching device transmits data to each transmission medium via the switching of the 2 channels per rotation of 360/2N degrees of said rotating frame, then transmits the data from the different channels for each 2 transmission medium, and when the interval between the two adjacent transmission medium pass near said receiving medium, switches the data to be transmitted to the two transmission medium to the same channel.

A data communication link system for a medical diagnosis apparatus that intermediumtes data communication between a rotating frame and a stationary frame comprising:

• a plurality of receiving medium provided to said stationary frame to locate around said rotating frame and corresponding to a plurality of channels;
• a plurality of transmission medium provided separately along the circumference of said rotating frame;
• and
• a switching device that assigns the plurality of channels to each transmission medium, and switches the data to be transmitted to the two transmission medium to the same channel when the interval between two adjacent transmission medium passes near said receiving medium.
