  • Method for recording a magnetic resonance image dataset, data medium, computer program product, and magnetic resonance installation
    Patent number: 11782116
    Abstract: A method for recording a magnetic resonance image dataset includes providing a magnetic resonance sequence with a series of sequence blocks, and providing at least one correction term to compensate for a magnetic field change. The magnetic field change is produced as a change of an actual magnetic field compared to a setpoint magnetic field by gradient pulses. The magnetic field change is established via a transfer characteristic of the gradient system of the magnetic resonance installation. The at least one correction term is used to compensate for the magnetic field change, and at least one magnetic resonance image dataset is recorded with the magnetic resonance sequence using the correction term.

  • Method, Apparatuses and System for Correcting an Influence of an Interference Effect on a Gradient System
    Publication number: 20230086826
    Abstract: In a method for correcting an influence of an interference effect on a gradient system of a MR apparatus during a MR scan, a gradient pulse is emitted by an amplifier of the gradient system, a gradient sequence is established, an output signal of the amplifier is captured for the gradient pulse, a transfer function is established, and an output signal of the amplifier is established such that the gradient system provides an expected gradient sequence.
