Abstract
In a method and apparatus for acquiring magnetic resonance image data of an object by execution of a magnetic resonance data acquisition sequence that includes at least one adiabatic radio-frequency pulse, at least one parameter for the object under investigation is acquired that is specific to the object under investigation. At least one pulse parameter of the at least one adiabatic radio-frequency pulse is adjusted using the at least one parameter for the object under investigation. Magnetic resonance image data of the object under investigation are acquired by execution of the magnetic resonance sequence, using the at least one adiabatic radio-frequency pulse with the adjusted at least one pulse parameter.

A method for acquiring magnetic resonance data from an object, comprising:
- providing a computer with an electronic designation of at least one parameter of an object that is specific to the object;
- in said computer, using said at least one parameter that is specific to the object to adjust at least one pulse parameter of an adiabatic radio-frequency pulse in a magnetic resonance data acquisition sequence that will be executed by a magnetic resonance scanner in order to acquire magnetic resonance data from the object;
- and
- from said computer, operating said magnetic resonance scanner to acquire said magnetic resonance data from the object using the adiabatic radio-frequency pulse with the adjusted at least one pulse parameter, and making the acquired image data available from the computer in electronic form as a data file.
A magnetic resonance apparatus comprising:
- a magnetic resonance scanner;
- a computer provided with an electronic designation of at least one parameter of an object that is specific to an object from which magnetic resonance data are to be acquired;
- said computer being configured to use said at least one parameter that is specific to the object to adjust at least one pulse parameter of an adiabatic radio-frequency pulse in a magnetic resonance data acquisition sequence that will be executed by the magnetic resonance scanner in order to acquire magnetic resonance data from the object;
- and
- said computer being configured to operate said magnetic resonance scanner to acquire said magnetic resonance data from the object using the adiabatic radio-frequency pulse with the adjusted at least one pulse parameter, and to make the acquired image data available from the computer in electronic form as a data file.
A non-transitory, computer-readable data storage medium encoded with programming instructions, said storage medium being loaded into a computer of a magnetic resonance apparatus that comprises a magnetic resonance scanner, and said programming instructions causing said computer to:
- receive an electronic designation of at least one parameter of an object that is specific to the object from which magnetic resonance data are to be acquired;
- use said at least one parameter that is specific to the object to adjust at least one pulse parameter of an adiabatic radio-frequency pulse in a magnetic resonance data acquisition sequence that will be executed by the magnetic resonance scanner in order to acquire said magnetic resonance data from the object;
- and
- operate said magnetic resonance scanner to acquire said magnetic resonance data from the object using the adiabatic radio-frequency pulse with the adjusted at least one pulse parameter, and make the acquired image data available from the computer in electronic form as a data file.
