Method for operating an mri system, an mri system, a control unit, a storage unit, a computer program, and an electronically readable data carrier

A magnetic resonance imaging (MRI) system comprising:

• at least one control unit configured to:
• receive at least one object parameter value of an object in an MRI examination in accordance with a predefined MRI protocol;
• determine a frequency distribution of deposition values of examined objects from available MRI examination datasets, each having the at least one object parameter value, wherein a respective MRI examination dataset of the MRI examination datasets comprises a respective deposition value and a respective object parameter value of a respective examined object;
• determine a reference deposition value of the examined objects from the frequency distribution of the deposition values of the examined objects for a predefined reference proportion in accordance with a predefined reference determining procedure;
• and
• determine, as a function of the reference deposition value, at least one MRI protocol parameter of the predefined MRI protocol for examining the object having the object parameter value in accordance with a predefined MRI protocol optimization procedure.

A control unit of a magnetic resonance imaging (MRI) system, wherein the control unit is configured to:

• receive at least one object parameter value of an object in an MRI examination in accordance with a predefined MRI protocol;
• determine a frequency distribution of deposition values of examined objects from available MRI examination datasets, each having the at least one object parameter value, wherein a respective MRI examination dataset of the MRI examination datasets comprises a respective deposition value and a respective object parameter value of a respective examined object;
• determine a reference deposition value of the examined objects from the frequency distribution of the deposition values of the examined objects for a predefined reference proportion in accordance with a predefined reference determining procedure;
• and
• determine, as a function of the reference deposition value, at least one MRI protocol parameter of the predefined MRI protocol for examining the object having the object parameter value in accordance with a predefined MRI protocol optimization procedure.
