Abstract
A method for determining a spoiler gradient of a magnetic resonance (MR) system is provided. At least one shim parameter that defines a shim magnetic field for compensating for B0 magnetic field inhomogeneities in a measurement volume of the MR system is received. As a function of the at least one shim parameter, at least one spoiler parameter that defines a spoiler gradient for canceling out a transverse magnetization is determined. The spoiler gradient is applied together with the shim magnetic field in a measurement of the MR system.
