摘要： A local transmit coil for a magnetic resonance tomograph is provided. The local transmit coil includes a signal transmission device for signal transmission to the magnetic resonance tomograph, and a transmission antenna for generating a magnetic excitation field. The local transmit coil further includes an evaluation device for monitoring a function of the local transmit coil. The evaluation device is configured to transmit a status signal relating to the local transmit coil via the signal transmission device.

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 method for generating a spatially resolved magnetic resonance dataset using a coil arrangement includes providing at least one correction datum based on receiver characteristics of the coil arrangement. The method also includes providing a magnetic resonance dataset with spatially resolved signal intensity data, and correcting the at least one signal intensity datum in the magnetic resonance dataset by the correction datum before or after providing the magnetic resonance dataset.
