A gradient coil system for a magnetic resonance apparatus has an area for receiving an examination subject and at least one gradient coil with an conductor arrangement for generating a magnetic gradient field having a main field component collinear to a basic magnetic field and at least one accompanying component that is perpendicular to the main field component, and at least one further conductor arrangement for feeding electrical current and which is fashioned and arranged for generating a non-homogeneous magnetic field such that the main field component, at least in the area, is approximately unaltered and such that the accompanying field component is reduced.

Gradient coil system for a magnetic resonance apparatus

In a method for the operation of a magnetic resonance apparatus, a prescribable event that can trigger a neural activity of an examination subject is initiated, the implementation of the event and the readiness of the examination subject to perceive the event that triggers the neural activity are monitored, and given a positive result of the monitoring, an image dataset of a region of the examination subject to be imaged, and to which the event can be allocated, is registered.

Method for the operation of a magnetic resonance apparatus and magnetic resonance apparatus for the implementation of the method

In a method for operating a magnetic resonance apparatus with a gradient coil system and an active shim system, shim currents of the active shim system and/or offset currents of the gradient coil system are adjusted corresponding to at least one subject-specific parameter of an examination subject.

Method for operating a magnetic resonance apparatus having an active shim system

In a method and device for increasing the efficiency of a gradient coil system in a magnetic resonance tomography apparatus to optimally use the efficiency of the gradient system, the individually different sensitivity of each patient regarding peripheral nerve stimulation (PNS) is determined prior to the MR examination by applying a variable electrical field, and the corresponding maximum magnetic field is determined by scaling, and the MR apparatus is correspondingly adjusted.
