Description

technical field [0001] The invention relates to nuclear magnetic resonance control technology, in particular to an FPGA-based nuclear magnetic resonance data communication realization device and method. Background technique [0002] In order to facilitate the operation and control of the MRI system by the operator, and facilitate the real-time control and centralized management of the scanning equipment, the MRI system is currently placed in the operating room with a console, and the spectrometer used for sequence scanning control is placed in the operating room. Inter-instrument implementation mode. Due to the different implementation structures of different nuclear magnetic resonance imaging systems, the data bus mode adopted by the console and the data communication protocol between the various modules inside the spectrometer are also different, so that the communication between the nuclear magnetic resonance spectrometer and the nuclear magnetic resonance console is diff...

Problems solved by technology

[0003] In the existing technology, there are two different methods to realize the NMR data communication between the console and the spectrometer. One is the data mode based on the ISA bus LAN technology using the copper medium. The data throughput of this mode is limited by However, it cannot be applied to the transmission of massive data with multiple receiving channels; the second is the optical fiber media-based PCI bus-based photoelectric conversion data communication method, which has a complex structure and high cost, and is difficult to support multi-channel data transmission
