Abstract
In a method for operating a magnetic resonance tomography device having a gradient system, which contains at least one gradient coil arrangement for generating a gradient field in a spatial direction and which also contains an energy supply device that is connected to the gradient coil arrangement, and wherein the gradient coil arrangement has at least one first sub-coil and one second sub-coil, and wherein the energy supply device is fashioned such that currents can be adjusted independently of one another in the sub-coils for the continuous adjustment of at least one property of the gradient field, the current in at least one of the sub-coils is determined and adjusted by solving an optimization task containing a target function and at least one secondary condition so that stimulations of a living examination subject are avoided.
