  • Publication number: 20240377487
    Abstract: A local coil including an antenna, base element, holding element, first and second guide mechanisms, and safety mechanism. The antenna receives high-frequency signals in a frequency range and power range of a magnetic resonance measurement and is mechanically connected to the holding element. The base element holds the holding element together with the antenna in a position for use on a diagnostically relevant body region of a patient. The first guide mechanism is mechanically connected to the base element and the holding element and positions the holding element variably relative to the base element. The second guide mechanism is mechanically connected to the holding element and the antenna and positions the antenna variably relative to the holding element. The safety mechanism prevents a collision between the antenna and the patient during a transfer of the holding element from an open position into a closed position using the first guide mechanism.
