Abstract

In a magnetic resonance apparatus and an operating method therefor, at least one limitation criterion, which describes the avoidance of excessive excitations in an interference spectrum in the magnetic resonance scanner of the apparatus, formed by an interference frequency or an interference frequency range, is specified by a limitation supply processor in order to check a scanning protocol, described by recording parameters, that is to be implemented. At least part of the temporal control sequence of the scanning protocol is determined as a pre-calculation sequence from the recording parameters by a simulation processor and the pre-calculation sequence is checked in a checking processor by the limitation criterion. Implementation of the scanning protocol is prevented when the limitation criterion is not fulfilled.
