    摘要： An adapter for a local coil for a magnetic resonance tomography device is provided. The adapter is placeable on a patient support for the magnetic resonance tomography device. The adapter includes an adapter upper part that is removably connectable to the local coil. The adapter also includes an adapter lower part that is removably connectable to the patient support. The adapter also includes a tilt device, by which the adapter upper part is movable relative to the adapter lower part.

    摘要： A radio-frequency transmission device for a magnetic resonance system to generate magnetic resonance exposures of an examination region of an examination subject, has: a first radio-frequency transmission antenna that emits radio-frequency signals in the examination region, a radio-frequency amplifier that supplies the first radio-frequency transmission antenna, with radio-frequency signals with a predetermined radio-frequency transmission power, and a second radio-frequency transmission antenna fashioned to label a medium flowing in the examination region and/or examination regions via emission of labeling radio-frequency signals, such that the medium can be identified in the generated magnetic resonance exposures of the examination region. The second radio-frequency transmission antenna is coupled with the radio-frequency amplifier to supply the first radio-frequency transmission antenna, such that it likewise supplies the second radio-frequency transmission antenna with radio-frequency signals with a predetermined radio-frequency transmission power for the emission of radio-frequency labeling signals.

    摘要： A gradient coil is connected to a controllable gradient amplifier via a first diagonal of a bridge circuit having four switches and unbiased diodes respectively connected parallel thereto. A capacitor that forms a resonant circuit together with the gradient coil is connected into the second bridge diagonal of the bridge circuit. A sinusoidal current is supplied through the gradient coil. Due to intentionally incomplete discharging of the capacitor at every other half-wave, an offset current can be superimposed on the sinusoidal current through the gradient coil.
