Abstract

An imaging apparatus has an MRT system with an MR receiving antenna configured to receive a first receive signal containing an MR signal from an object to be examined during an examination period. The imaging apparatus includes a modality for examining the object and/or for acting on the object via mechanical or electromagnetic waves, wherein the modality has an electronic circuit. The imaging apparatus includes an auxiliary antenna arranged and configured to receive a second receive signal containing an interference signal generated by the electronic circuit during the examination period. The imaging apparatus has a processing system configured to suppress interference in the first receive signal based on the first and the second receive signal.
