Magnetic resonance apparatus and operating method with adjustment of the excitation angle dependent on data acquisition field of view

A magnetic resonance tomography (MRT) apparatus comprising:

• an MRT data acquisition scanner comprising a receiving space in which a target object is received;
• a control computer configured to operate the MRT data acquisition scanner in order to execute an MRT data acquisition protocol so as to acquire MRT data from the target object, said MRT data acquisition protocol comprising at least one RF pulse;
• a detector that detects and provides said computer with a specification of a field of view that encompasses a portion of said receiving space from which said MRT data are to be acquired from said target object;
• said computer being configured to automatically determine a relative position of the field of view in relation to said receiving space of the MRT scanner;
• and
• said computer being configured to automatically adjust said at least one RF pulse dependent on the determined relative position of the field of view, so as to change an excitation angle produced by said at least one RF pulse in said field of view, compared to an excitation angle produced by the original RF pulse in said MRT data acquisition protocol.

A non-transitory, computer-readable data storage medium encoded with programming instructions, said storage medium being loaded into a control computer of a magnetic resonance tomography (MRT) apparatus that comprises an MRT data acquisition scanner having a receiving space in which a target object is received in order to acquire MRT data from the target object according to an MRT data acquisition protocol that comprises at least one RF pulse, said programming instructions causing said control computer to:

• receive a specification of a field of view that encompasses a portion of said receiving space from which said MRT data are to be acquired from said target object;
• determine a relative position of the field of view in relation to said receiving space of the MRT scanner;
• and
• adjust said at least one RF pulse dependent on the determined relative position of the field of view, so as to change an excitation angle produced by said at least one RF pulse in said field of view, compared to an excitation angle produced by the original RF pulse in said MRT data acquisition protocol.
