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 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 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.

摘要： In a method for controlling a magnetic resonance system with multiple radio-frequency transmission channels, via which parallel RF pulse trains are emitted in operation, as well as a magnetic resonance system and a pulse optimization device therefor, RF pulse trains respectively include at least one radio-frequency pulse. The RF pulse trains are initially determined so that a minimum B1 field maximum value is not exceeded by the radio-frequency pulse. In an examination subject-specific adjustment step, a current component-dependent B1 field maximum value is then determined, and the radio-frequency pulse is temporally shortened, with its amplitude being increased dependent on the current component-dependent B1 field maximum value.

摘要： In a method and magnetic resonance system for the acquisition of magnetic resonance data in a selected region of an examination subject, magnetic resonance data are acquired more than once using a magnetic resonance system, magnetic resonance data are acquired more than once from a selected partial region the portion of k-space filled with data corresponding to the selected region of the subject, and the multiply acquired magnetic resonance data are processed into a data set, the aforementioned partial region is selected so as to be located decentrally in k-space, meaning that it is asymmetrical relative to the center of k-space.
