Abstract:
1. A method of generating a pulse sequence that operates a magnetic resonance system comprising: in a processor, generating a pulse sequence, comprised of a plurality of pulses in a chronological succession, configured to operate a magnetic resonance system, in which a basic magnetic field is present, in order to acquire magnetic resonance data from a subject within the magnetic resonance system, said subject comprising a non-tissuous object therein that produces localized inhomogeneity in said basic magnetic field that interferes with the acquisition of said magnetic resonance data, said processor configuring said pulse sequence with at least two radio-frequency (RF) pulses; in said processor, also setting respective bandwidths of at least two of said RF pulses to be matched so as to configure said at least two of said RF pulses with matched bandwidths in order to respectively excite congruent slices of said examination subject when radiated into the subject under an effect of a slice selection gradient having an identical amplitude during each of said at least two of said RF pulses in said pulse sequence, with the congruency of said slices produced by said matched bandwidths causing non-linearity and inhomogeneity in said slices, produced by said non-tissuous object, to be the same in each of said slices so that said slices are not inconsistently excited with respect to each other; and making said pulse sequence, with said at least two of said RF pulses having said matched bandwidths, available at an output of said processor in an electronic form that is configured to operate said magnetic resonance system.
