摘要： The invention relates to a method for compensating for a magnetic field disturbance affecting a magnetic resonance device, whereby the magnetic field disturbance is caused by a deflection of a component of the magnetic resonance device. To this end, the deflection or a variable causing the deflection is acquired in timed-dependent fashion, a mathematical field disturbance model is provided which models the effect the of the deflection on the magnetic field, and the acquired deflection or the variable causing the deflection is converted by means of the field disturbance model into a control variable for a compensation magnetic field generator or a high-frequency antenna. The compensation magnetic field generator controlled in this manner generates, for example, a compensation magnetic field which compensates for the magnetic field disturbance. The high-frequency antenna controlled in this manner is, for example, matched in its mid frequency to the magnetic field disturbance.

摘要： In a gradient coil and a method to manufacture a gradient coil for a magnetic resonance apparatus, the gradient coil has at least one saddle coil, the saddle coil having a spatially shaped, electrically conductive plate with a line-shaped recess penetrating the plate. Conductor structures that create a gradient magnetic field in an examination region when a current signal flows therethrough are formed by the recess and by the shaping of the plate. The recess is filled with an electrically insulating material before implementation of the spatial shaping.

摘要： A controller of a magnetic resonance system determines an activation signal vector based on a target field predetermined for the controller in conjunction with field characteristics of field coils known to the controller. The activation signal vector includes a respective activation signal for each field coil. The controller determines the activation signal vector such that within a predetermined examination volume of the magnetic resonance system, any deviation of an ideal field that would result if ideal coils were subjected to the activation signals of the activation signal vector from the target field is minimized. The controller determines a compensation signal vector based on the activation signal vector in conjunction with eddy current characteristics of the field coils known to the controller. The compensation signal vector is used to minimize a deviation of an actual field from the target field within the predetermined examination volume of the magnetic resonance system.
