摘要： A method for actuating a magnetic resonance system having a radiofrequency unit designed to generate a radiofrequency pulse for the saturation of nuclear spins in an area under examination of an object under examination. The method includes loading a B0 map of the magnetic resonance system; loading frequency information on nuclear spins to be saturated in the area under examination; ascertaining at least one global RF saturation pulse for the global saturation of the nuclear spins to be saturated on the basis of the B0 map and the frequency information; and outputting the RF saturation pulse via the radiofrequency unit of the magnetic resonance system.

摘要： An X-ray tube bearing assembly may include a bearing housing including an accommodating cavity; and a bearing core accommodated in the accommodating cavity. The bearing housing may include first and second portions. The second portion surrounds and forms a portion of the accommodating cavity to accommodate the bearing core. The first portion extends out of the second portion and surrounds and forms another portion of the accommodating cavity, and the other portion of the accommodating cavity forms an accommodating hollow cavity. The first portion may have a different structural rigidity to that of the second portion.

The at least one projection image includes a plurality of pixels, each pixel including a pixel value. The method includes determining at least one corrected projection image based on the at least one projection image via a computing circuit; reconstructing the at least one slice image based on the at least one corrected projection image; and providing the at least one slice image. The determining includes determining an average pixel value in at least one subarea of the at least one projection image, a correction value by multiplying the average pixel value by a scatter factor, and a plurality of corrected pixel values by subtracting the correction value from the plurality of pixel values. The corrected projection image includes pixels including the plurality of corrected pixel values.

摘要： A method for operating a magnetic resonance facility in which a measurement gradient pulse is used to record magnetic resonance signals for sampling k-space along a trajectory section. The recorded magnetic resonance signals are assigned to k-space points using a shape function describing the time profile of the measurement gradient pulse. To correct deviations of the real time profile of the measurement gradient pulse from an assumed target profile, a first correction measurement is performed to ascertain first magnetic resonance signals of the trajectory section. A second correction measurement is then performed using a reference sampling pattern or a reference gradient pulse with fewer deviations from an assigned reference target profile. If a deviation criterion is met, a correction function for the shape function is ascertained by aligning the first and second magnetic resonance signals to one another, providing correction information to be used in an imaging measurement.

摘要： In a method for creating an image dataset of a mapping area situated in a measuring volume, k-space corresponding to the mapping area may be read out and image data may be reconstructed based on recorded first and second raw data points of k-space. The reading out of k-space may include: switching a gradient in the slice selection direction and a phase-encoding gradient in at least one further encoding direction, radiating a non-slice-selective radio-frequency (RF) excitation pulse, recording echo signals and storing them as first raw data points along a radial k-space trajectory predefined by the full strength of the phase-encoding gradients (Gp) further switched during recording of the echo signals, and reading out k-space corresponding to the mapping area as second raw data points.
