Abstract:
A method for operating a magnetic resonance tomography apparatus having a gradient system with at least one gradient coil arrangement for generating a gradient field in a spatial direction, said gradient field having gradient field properties, and having an energy supply device connected to the gradient coil arrangement, and said gradient coil arrangement including at least one first sub-coil and one second sub-coil, said method comprising the steps of:via said energy supply device, adjusting respective currents in said first sub-coil and said second sub-coil independently of each other; and continuously adjusting at least one of said gradient field properties by determining and setting the current in at least one of said first and second sub-coils by solving an optimization task containing a target function and at least one secondary condition for avoiding stimulations in a living examination subject in said tomography device.
