Embodiment Construction

[0042] The present invention will be further described in detail in conjunction with the following specific embodiments and accompanying drawings. The process, conditions, experimental methods, etc. for implementing the present invention, except for the content specifically mentioned below, are common knowledge and common knowledge in this field, and the present invention has no special limitation content.

[0043] In existing communication and other transmission systems, functions such as data encoding and serial-to-parallel conversion are mostly realized by dedicated components. In view of the large number of magnetic resonance receiving channels, the large amount of signal data, the high real-time requirements of the system, the very limited installation space of the circuit and the need to work in a strong magnetic field environment, in order to realize the serial transmission of magnetic resonance data, it is necessary to complete the Multiplexing, data encapsulation, ser...

Abstract

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.

Description

technical field [0001] The invention belongs to the technical field of magnetic resonance, in particular to a magnetic resonance multi-channel digital transmission system and a data transmission method thereof. Background technique [0002] Magnetic resonance imaging has the advantages of no radiation hazard, arbitrary direction and multi-parameter imaging, and can provide multiple physiological information at the same time, so it is more and more widely used in the field of medical imaging diagnosis. Obtaining clearer images at a faster speed has always been the goal of the development of magnetic resonance imaging technology. In recent years, the emergence of multi-channel coil acquisition technology and the development of parallel imaging technology have increasingly become the main way to increase the speed of MRI. New technologies require MRI receiving systems to provide more reliable and efficient data transmission methods. [0003] Due to the constraints of the stro...
