Multi-nuclide synchronous integrated magnetic resonance imaging nuclide quantification system and use method thereof

The invention provides a multi-nuclide synchronous integrated magnetic resonance imaging nuclide quantification system and a use method thereof, the quantification system comprises n sealed containers, n is greater than or equal to 5 and is an integer, and the n sealed containers are sequentially labeled as a container I, a container II, a container III,..., a container n; the sealed containers are filled with mixtures containing all pre-imaging nuclides, the non-1H pre-imaging nuclides filled in the second container, the third container... and the n container keep known concentration gradients, and the number of the concentration gradients is n-1. When the quantitative system is used, a radio frequency field correction coefficient distribution diagram is calculated based on an image of a first container; placing the remaining containers around the imaging part and imaging at the same time, and correcting the obtained image by using the radio frequency field correction coefficient distribution map; and finall
