Magnetic resonance tomography having dual recording for noise reduction

A magnetic resonance tomography system comprising:

• a scanner unit configured to:
• perform a first MR recording so as to map an object in accordance with a first k-space scanning scheme to generate first MR data that represents the object, wherein during the first MR recording at least one first excitation pulse is transmitted in accordance with a first pulse sequence in a direction of the object;
• and
• perform a second MR recording that is different from the first MR recording to generate second MR data;
• and
• a computing unit configured to
• determine in dependence upon the second MR data a noise component that represents an influence of at least one external noise source;
• and
• generate an MR image in dependence upon the first MR data and the noise component.

A non-transitory computer implemented storage medium that stores machine-readable instructions executable by at least one processor, the machine-readable instructions comprising:

• performing a first MR recording to map an object and to generate first MR data that represents the object, wherein the first MR recording is performed in accordance with a first k-space scanning scheme and during the first MR recording at least one first excitation pulse is transmitted in accordance with a first pulse sequence in a direction of the object;
• performing a second MR recording that is different from the first MR recording to generate second MR data;
• determining a noise component based on the second MR data, wherein the noise component represents an influence of at least one external noise source;
• and
• generating an MR image based on the first MR data and the noise component.
