Abstract: In a method to determine a control sequence for a magnetic resonance imaging system in order to acquire echo signal-based raw magnetic resonance data in k-space along one or more trajectories on the basis of the control sequence, the control sequence is optimized so that, to control a gradient magnetic field for at least a predetermined portion of the control sequence, a change of an attribute of the gradient magnetic field is limited. The limitation takes place so that a momentary amplitude change rate of the gradient magnetic field falls below a predetermined amplitude change rate limit value, and/or so that a momentary direction change rate of the gradient magnetic field falls below a predetermined direction change rate limit value, and/or so that a momentary gradient change rate of the gradient magnetic field that is based on a combination of the momentary amplitude change rate and the momentary direction change rate falls below a predetermined gradient change rate limit value.

Abstract: In a method and computer for the representation of magnetic resonance data, and a method and computer for storing magnetic resonance data in a computer, magnetic resonance data are acquired from an object under investigation, the acquired data represents a spatially resolved distribution of values of a number of tissue parameters in the object. A tree structure is created that has a trunk and a number of first tree elements branching from the trunk. A first tissue parameter among the multiple tissue parameters is assigned to the trunk and a second tissue parameter among the multiple tissue parameters is assigned to the number of first tree elements. The tree structure with respect to the acquired values of the multiple tissue parameters, so an adapted tree structure is compiled. The adapted tree structure is presented for a user on a display monitor.

Abstract: A continuously variable saturable shunt reactor includes a laminated core having two wound limbs for each phase connected by yokes. A network winding branch is disposed on each limb, high-voltage ends of winding branches of a phase are connected to a phase conductor and low-voltage ends of winding branches are connected to a DC voltage source, to reduce power of the DC voltage sources, degree of distortion of the operating current and control error, and to reduce the number of DC voltage sources. The DC voltage source includes two stabilized, single-pole-grounded power converters with opposite polarities and two electronic transistor changeover switches controlled by a control system, for each phase. The control system feeds direct current to the winding branches of a phase in pulses using the switches and the direct current is fed into the winding branches at opposite poles from different power converters.

Abstract: In a method and imaging apparatus for acquiring multi-contrast magnetic resonance (MR) data, a data acquisition scanner is operated in a simultaneous multislice data acquisition sequence to radiate at least one single-band binomial radio-frequency (RF) pulse, that excites fat protons in at least some slices of an examination subject from which MR raw data are to be acquired simultaneously, and leaving water in a longitudinal plane for those at least some slices, and leaving all spin species in a longitudinal plane in others of the slices that are to be acquired simultaneously. A spoiler gradient is subsequently activated that dephases the fat protons that were excited. The scanner is then operated to execute an MR data acquisition sequence with excitation by radiation of multi-band RF pulses. MR raw data resulting from excitation of the fat protons, and MR raw data acquired with said multi-band RF excitation, are compiled in respective data files.

Abstract: Embodiments relate to a magnetic resonance imaging (MRI) technique in which the two-dimensional (2D) Displacement Encoding with Stimulated Echoes (DENSE) imaging technique and the multiband technique are combined to provide a 2D multi-slice quantitative assessment of displacement, deformation, and mechanics indices of tissue. The scan time is equivalent to the short scan time of the conventional single slice 2D imaging while providing spatial volumetric coverage similar to three-dimensional (3D) imaging. The techniques are combined in both the sequence (i.e., data acquisition) and reconstruction sides. Quantification of tissue displacement and motion is achieved through the combination and further evaluation of tissue mechanical properties is provided by calculating different indices based on the displacement and motion values.
