摘要:
In accordance with a method for operating an MRT system a first MR recording is performed so as to map an object to generate first MR data that represents the object. 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. A second MR recording that is different from the first MR recording is performed to generate second MR data and a noise component is determined in dependence upon the second MR data by a computing unit and the noise component represents an influence of at least one external noise source. An MR image is generated by the computing unit in dependence upon the first MR data and in dependence upon the noise component.
