  • Patent number: 11357418
    Abstract: A control device establishes a change in a main magnetic field expected for a respective time instant and based on the established expected change in the main magnetic field, correctively adjusts the main magnetic field and/or a nominal receive frequency of the RF receive coil and/or a transmit frequency for subsequent RF transmit pulses and/or takes the expected change in the main magnetic field into account in the evaluation of the received MR signals. At least for some of the RF transmit pulses, the control device acquires, via a sensor device, a portion of the respective radiofrequency wave supplied to the RF transmit coil. The controller extracts therefrom an oscillation corresponding to a respiratory motion of the patient and based on the variation with time of the extracted oscillation, establishes the change in the main magnetic field expected for the respective time instant.

  • Patent number: 10761164
    Abstract: A method for generating a spatially resolved magnetic resonance dataset using a coil arrangement includes providing at least one correction datum based on receiver characteristics of the coil arrangement. The method also includes providing a magnetic resonance dataset with spatially resolved signal intensity data, and correcting the at least one signal intensity datum in the magnetic resonance dataset by the correction datum before or after providing the magnetic resonance dataset.
