Abstract: A system and method are provided for operating a magnetic resonance tomograph. A transmitter of the magnetic resonance tomograph transmits a predetermined test pulse with a reduced power. The magnetic resonance tomograph receives the test pulse with the local coil. A controller compares the received test pulse with a predetermined pulse response and emits a warning signal when the received test signal differs from the predetermined pulse response.

Abstract: A breast coil arrangement for magnetic resonance applications has a placement web that allows an examination subject to lie with her sternum on the placement web with each breast in a receptacle respectively on opposite sides of the placement web. The breast receptacles have limiting elements whose spacing from one another can be adjusted. Multiple array coils are respectively arranged in the limiting elements and are stationary relative to the limiting elements. Each breast receptacle is surrounded by a volume coil that is stationary relative to the placement web. The volume coils are arranged centrally and orthogonally relative to the array coils and surround the array coils. The volume coils are decoupled from the array coils. A spectroscopy phantom can be arranged in proximity to the placement web.
