Calculation of shim settings for magnetic resonance imaging includes defining an examination volume for the magnetic resonance imaging in a body of the examination object, determining a local shim volume, which includes a subregion of the examination volume, calculating shim settings, wherein a tissue, which is present in the local shim volume, of the body of the examination object is incorporated into the calculation of the shim settings, and acquiring magnetic resonance raw data of the examination volume by operation of a magnetic resonance scanner, using the calculated shim settings.

Method and apparatus for magnetic resonance imaging

A local coil for an imaging system includes an anterior torso part and a posterior torso part that are detachably connected to one another with a fastening device.

Local coil

An arrangement to transmit magnetic resonance signals has a local coil composed of a number of individual antennas for acquisition of radio-frequency signals of a magnetic resonance examination. Preamplifiers amplify the radio-frequency signals, and a transmission device transmits the radio-frequency signals from the local coil to the preamplifiers. The transmission device is fashioned as a readout coil and has a number of individual antennas. The individual antennas of the readout coil are magnetically coupled with the individual antennas of the local coil, with the individual antennas of the local coil and the individual antennas of the readout coil forming a linear MIMO transmission system describable by a transmission matrix.
