摘要： 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.

摘要： A method for recording a magnetic resonance data set relating to a region that is moved at least partly and periodically includes prompting a trigger signal. The method also includes emitting a saturation pulse to at least partially saturate magnetization of an examination region as a function of the trigger signal.

摘要： A method for monitoring a temporal change in a magnetic field in a magnetic resonance device, as well as an evaluation unit, a magnetic resonance device, and a computer program product for performing the method are provided. The method provides that a position-dependent magnetic field distribution that is produced by the plurality of gradient coils is provided with a plurality of monitoring points. In addition, time-dependent gradient values of the plurality of gradient coils are ascertained. Based on position-dependent magnetic field distribution and the time-dependent gradient values, the temporal change in the magnetic field is ascertained. The temporal change in the magnetic field is monitored by comparing the temporal change in the magnetic field with at least one limit value.

摘要： A method for operating a magnetic resonance apparatus by a safety unit, taking into account persons fitted with an implant, a safety unit, a safety system, a magnetic resonance apparatus, and a computer program product are provided. The magnetic resonance apparatus includes a first part and a second part. The first part is operated separately from the second part and includes the safety unit. During an examination of a person fitted with an implant, the safety unit checks that the magnetic resonance apparatus, in a restricted operating mode, is complying with implant-conformant limit values.

摘要： A method for adapting activation parameters used to generate a pulse sequence when activating a magnetic resonance system is provided. The method includes determining stimulation values for the pulse sequence based on predefined activation parameters. The stimulation values represent a stimulation exposure of a patient. Test regions that exhibit stimulation maxima are identified in the pulse sequence, and the identified test regions are tested with respect to compliance with a predefined stimulation limit value.

摘要： A method for setting an operating parameter of a medical device is provided. The method includes determining a current operating mode of the medical device. A time span available for setting the operating parameter is derived from the determined current operating mode. A setting range of the operating parameter necessary for fulfilling a pre-determined criterion is determined. A setting time necessary for setting the operating parameter according to the determined setting range is determined, and the operating parameter is set according to the setting range, provided the time span available for the setting is at least as long as the necessary setting time.
