The invention discloses a magnetic
resonance multichannel digital
transmission system, including a multipath data
multiplexing unit, a data encapsulation unit, a high speed serial transmission unit, a
fiber transmission unit, a
fiber reception unit, a high speed serial reception unit, a data unpacking unit and a multipath data demultiplexing unit. Multichannel magnetic
resonance digital signals after sampling and front-end
processing are subjected to
multiplexing according to magnetic
resonance data word lengths, obtained data of all channels are polled as a frame, and
frame synchronization codes required in demultiplexing are inserted at a frame header, and thus the real-time property and the integrity of magnetic resonance data are ensured. Synchronous
clock information is inserted in line coding, and thus transmission of magnetic resonance data and
clock can be completed using a single channel, and
system equipment is simplified.
FPGA chip programming realization is used to improve the
system integration degree. The invention also provides a magnetic resonance multichannel
data transmission method.
