1. An imaging apparatus with an examination area for placing an object to be examined, the imaging apparatus comprising:
a magnetic resonance (MR) tomography system with an MR receiving antenna arranged and configured to receive a first receive signal containing an MR signal from the object during an examination period;
a modality configured to at least one of (i) examine the object via mechanical or electromagnetic waves or (ii) act on the object via the mechanical or electromagnetic waves, wherein the modality has an electronic circuit to operate the modality;
an auxiliary antenna configured to receive, during the examination period, a second receive signal containing an interference signal generated by the electronic circuit and emitted into the examination area; and
a processing system configured to suppress interference in the first receive signal based on the first receive signal and the second receive signal, to reduce an influence of the interference signal.
