Abstract: A system includes two magnetic resonance tomography units. Each of the magnetic resonance tomography units includes a magnet unit having a magnetic controller for generating a homogenous magnetic field. The magnetic controller is configured to change the homogenous magnetic field in a short, predetermined time within image acquisition of an object under examination, such that a Larmor frequency for a predetermined layer of the object under examination remains in a predetermined frequency range. A first magnetic resonance tomography unit has a first predetermined frequency range, and a second magnetic resonance tomography unit has a second predetermined frequency range. The first predetermined frequency range and the second predetermined frequence range are disjoint.

Abstract: A magnetic resonance tomography unit includes a magnet unit having a magnetic controller for generating a homogenous magnetic field. The magnetic controller is configured to change the homogenous magnetic field in a short, predetermined time within image acquisition of an object under examination, such that a Larmor frequency for a predetermined layer of the object under examination remains in a predetermined frequency range. A layer in the object under examination is selected and a value for the homogenous magnetic field, in which the Larmor frequencies of the nuclear spins of the layer lie in a predetermined frequency band, is determined by a control unit taking into account a predetermined magnetic field gradient. The established value for the homogenous magnetic field and the predetermined magnetic field gradient is set by the magnetic controller, and an excitation pulse, frequencies of which only lie in the predetermined frequency band, is emitted.

Abstract: A magnetic resonance tomography system may include an adapted ventilator with an air exit. The adapted ventilator may include an airstream generator (e.g., with a motor), an air volume amplifier which is arranged at the air exit and/or includes the air exit, and an air line section which carries an airstream that is generated by the airstream generator to the air volume amplifier. The air volume amplifier may be configured to increase an air volume of the airstream that is carried via the air line section to the air volume amplifier, so that it outputs an airstream with increased air volume.

Abstract: A magnetic resonance tomography (MRT) unit includes a field magnet, a transmitter, and a transmitting antenna. The MRT unit also has a transmission interference suppression facility with a transmission interference suppression controller, a plurality of sensors, and a transmission interference suppression antenna. The transmission interference suppression facility is configured to pick up, with the sensors, an excitation signal of the transmitter, determine, with the transmission interference suppression controller, a transmission interference suppression signal as a function of the excitation signal of the transmitter, and emit the signal via the transmission interference suppression antenna, so that at a predetermined location outside of the MRT unit, an electromagnetic alternating field of an excitation signal emitted by the transmitter via the transmitting antenna is attenuated.
