摘要： A method for determining a position of a mobile device relative to a B0 field magnet along a z-coordinate axis, and a device and a magnetic resonance tomography unit for performing the method are provided. The device includes a magnetic field strength sensor arranged in a fixed relative position. A characteristic magnetic field strength Bref of the B0 field magnet that emerges for a plurality of x-y coordinate pairs with a same reference z-coordinate zref is ascertained. The device is moved along the z-coordinate axis until the magnetic field strength sensor measures the characteristic magnetic field strength Bref.

摘要： A printed circuit board (PCB) is flat, providing a top side and a bottom side. A plurality of terminations is disposed on the top side in proximity to one end face of the PCB. Each termination has at least one contact that is connected to a respective conductor track of the PCB. The respective conductor track is connected to a respective local coil or to a contact disposed on the top side or the bottom side of a respective further termination. The local coil and/or at least one of the further terminations are disposed in proximity to the other end face. A basic shield impervious to frequencies in a magnetic resonance range is disposed on the top side and/or the bottom side, and an auxiliary shield electrically connected to the basic shield and impervious to frequencies in the magnetic resonance range is disposed on narrow sides of the PCB.
