1. A method for acquiring magnetic resonance (MR) data, comprising:

  • in a control computer of an MR imaging system, defining multiple individual data sets, respectively corresponding to multiple diffusion models, with each of said individual data sets being comprised of multiple diffusion image individual data subsets that are to be acquired on one or more specific shells, respectively, and in one or more gradient directions, respectively, and with different specific shells among the multiple shells having different diffusion factors;

    defining the combined data set by combining a number of the diffusion image individual data subsets to be acquired on a number of adjacent shells in a number of the individual data sets to form a number of second diffusion image combined data subsets to be acquired on a normalized shell in the combined data set, with the number of second diffusion image combined data subsets is greater than or equal to the maximum value of numbers of the diffusion image individual data subsets acquired on the adjacent shells in each of the individual data sets, the specific shell including the adjacent shells; and

    from the control computer, operating a data acquisition scanner of the MR imaging system in order to acquire MR data corresponding to the defined combined data set, and making the acquired MR data available in electronic form from the control computer as an MR data file.
