Method and magnetic resonance apparatus for performing an adjusting measurement

A magnetic resonance (MR) apparatus comprising:

• an MR scanner;
• a control computer configured to operate the MR scanner prior to operating the MR scanner in a scan to obtain a diagnostic MR dataset, while an examination subject is situated therein, to perform a localizing MR measurement of the subject, thereby obtaining a localization MR dataset of a region of the subject;
• a processor provided with said MR localization dataset, said processor being configured to identify at least one examination region of the subject within said MR localization dataset that is smaller than the total region of said localization MR dataset;
• said processor being configured to select an identified examination region from the MR localization dataset as a selected examination region;
• and
• said processor being configured to determine at least one adjusting parameter, restricted to said selected examination region, and to make said adjusting parameter available as an electronic signal at an output of the processor in a form for operating said MR scanner in an adjusting measurement of the subject, using said adjusting parameter, to acquire MR data from said selected examination region, and to use the MR data acquired in said adjusting measurement to set at least one parameter for operating said MR scanner in said scan to obtain said diagnostic MR dataset.

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

• operate the MR scanner, while an examination subject is situated therein, to perform a localizing MR measurement of the subject prior to operating the MR scanner in a scan to obtain a diagnostic MR dataset, thereby obtaining a localization MR dataset of a region of the subject;
• identify at least one examination region of the subject within said MR localization dataset that is smaller than the total region of said localization MR dataset;
• select an identified examination region from the MR localization dataset as a selected examination region;
• and
• determine at least one adjusting parameter, restricted to said selected examination region, and make said adjusting parameter available as an electronic signal at an output of the computer system in a form for operating said MR scanner in an adjusting measurement of the subject, using said adjusting parameter, to acquire MR data from said selected examination region, and use the MR data acquired in said adjusting measurement to set at least one parameter for operating said MR scanner in said scan to obtain said diagnostic MR dataset.
