Abstract

The invention provides a multichannel data transmission method. Data heads are embedded in data at a transmitting end, the data heads include frame numbers, symbols and channel numbers, and the data with the data heads are transmitted to a receiving end; the receiving end comprises multiple window bodies which parse the data heads so that the frame numbers, the symbols and the channel numbers are obtained through parsing; and the data corresponding to the data heads are filled in the corresponding positions of the corresponding window bodies according to the parsed frame numbers, the symbols and the channel numbers. The requirement of synchronous transmission for timing sequence is reduced by the technical scheme, data transmission of different channels does not need to consider time delay difference between channels, the same transmission medium is not needed, multiple channels do not need to be strictly aligned, and even multiple transmitters can be asynchronous so that data transmission efficiency can be enhanced. The invention also provides a multichannel data transmission system.

Description

technical field [0001] The invention relates to the field of magnetic resonance imaging, in particular to a multi-channel data transmission method and system. Background technique [0002] In magnetic resonance imaging technology, imaging speed has always been an important factor to be considered in clinical magnetic resonance applications. Therefore, since the advent of magnetic resonance, researchers have been working to increase the speed of imaging. In the early days of clinical MRI, even simple detection required hours of scan time. In the 1990s, with the performance enhancement of field strength, gradient hardware, and pulse sequence, the imaging speed was greatly improved. However, the imaging speed is also greatly dependent on the performance of the gradient system of the magnetic resonance equipment, and the development of hardware also greatly restricts the further improvement of the speed, because of physical and physiological limitations, and too fast field gra...
