摘要：
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.
