Method and magnetic resonance imaging apparatus for providing a planning environment for magnetic resonance imaging

A magnetic resonance (MR) apparatus comprising:

• an MR data acquisition scanner
• a computer that receives an electronic input into a computer that selects an MR sequence for MR imaging of a subject with said MR data acquisition scanner, the MR sequence comprising a plurality of repetitions of a cycle of the MR sequence;
• said computer being configured to acquire, for the selected MR sequence, an adjustment parameter that is specific to the subject;
• said computer being configured to specify a limit value for a loading parameter of the subject;
• said computer being configured to determine a parameter range for an imaging parameter of the selected MR sequence using said adjustment parameter and said specified limit value for the loading parameter to determine the loading parameter of the subject by multiplying a loading parameter for one of the cycles by a number of the cycles in the MR sequence, the loading parameter being produced by executing said MR sequence, and comparing the loading parameter in the computer with the limit value for the loading parameter;
• and
• a user interface in communication with said computer, said computer being configured to present a planning environment at said user interface for the MR imaging of the subject, in which only the determined parameter range can be set for the imaging parameter.

A non-transitory, computer-readable data storage medium encoded with programming instructions, said storage medium being loaded into a computer of a magnetic resonance (MR) apparatus, and said programming instructions causing said computer to:

• receive an electronic input that selects an MR sequence for MR imaging of a subject with said MR apparatus, the MR sequence comprising a plurality of repetitions of a cycle of the MR sequence;
• for the selected MR sequence, acquire an adjustment parameter that is specific to the subject under examination;
• specify a limit value for a loading parameter of the subject under examination;
• determine a parameter range for an imaging parameter of the selected MR sequence based using adjustment parameter and said specified limit value for the loading parameter to determine the loading parameter of the subject by multiplying a loading parameter for one of the cycles by a number of the cycles in the MR sequence, the loading parameter being produced by executing said MR sequence, and comparing the loading parameter in the computer with the limit value for the loading parameter;
• and
• at a user interface in communication with said computer, present a planning environment for the MR imaging of the subject under examination, in which only the determined parameter range can be set for the imaging parameter.
