Abstract: In a method for correction of a B0 field map measured with a magnetic resonance device, that describes deviations from a nominal field strength in the homogeneity area of the magnetic resonance device by deviations from a nominal frequency for protons bonded to water, the deviations being represented as Larmor frequency values for different picture elements shifted by chemical shifts, the B0 field map is recorded with spins of the fat and water protons not in phase. The B0 field map is segmented by evaluating the differences of the Larmor frequency values of adjacent picture elements of the B0 field map in at least two contiguous clusters. For each cluster, a decision is made on the basis of a smoothness criterion and a compactness criterion as to whether a cluster containing a majority of protons bonded into fat is involved.

Abstract: The invention relates to a method for the production of a soft magnetic core for generators and generator with a core of this type. To produce a core, a plurality of magnetically activated and/or magnetically activatable textured laminations is produced from a CoFeV alloy. This plurality of laminations is then stacked to form a core assembly. Then the core assembly, if consisting of magnetically activatable laminations, is magnetically activated. Finally, the magnetically activated core assembly is eroded to produce a soft magnetic core. A core of this type is suitable for a generator with a stator and a rotor for high-speed aviation turbines, the laminations in the core assembly being oriented in different texture directions relative to one another.

Abstract: A sequence of a plurality of pulses following one another in time is applied to an examination volume of a magnetic resonance apparatus using a plurality of transmission antennas. In order to transmit the respective pulse, the plurality of transmission antennas are actuated using a specific transmission signal by a control device of the magnetic resonance apparatus. The transmission signals have predetermined phase and amplitude relationships to one another. The phase and amplitude relationships of a first pulse of the sequence S differ from the phase and amplitude relationships of a second pulse of the sequence.

Abstract: In a method and magnetic resonance (MR) system to acquire MR data within a volume segment, the MR data are repeatedly acquired with a sequence that which includes the following steps. A first resonant RF pulse is radiated and a second resonant RF pulse is radiated. A dephasing first gradient is applied after the first resonant RF pulse and before the second resonant RF pulse. A third resonant RF pulse is radiated after the second resonant RF pulse. A second gradient is applied after the third RF pulse in order to refocus a stimulated echo of a magnetization component prepared by the first gradient. MR data are read out, and a fourth resonant RF pulse is radiated after the readout of the MR data, to reduce the longitudinal magnetization.

Abstract: In a magnetic resonance method and apparatus to determine a subject-specific B1 distribution of an examination subject in a measurement volume in the magnetic resonance apparatus, a first measurement data set of the examination subject is acquired using a first pulse sequence, a second measurement data set of the examination subject is acquired using a second pulse sequence, and a third measurement data set of the examination subject is acquired using a third pulse sequence. A first phase is determined from the first measurement data set, a second phase from the second measurement data set and a third phase from the third measurement data set. A relevant phase shift is calculated from the first phase, the second phase and the third phase, and the B1 distribution are determined from the calculated relevant phase shift.

Abstract: A method and an apparatus for determining the particle content of a particle stream using a source of light and two receivers arranged offset from one another in the flow direction of the particle stream. The receivers provide an electrical signal to an evaluation unit as a function of the radiation intensity which they receive, and this signal makes possible a determination of the flow velocity and particle size. Coincident passage of two particles is indicated by a pulse occurring in the signal due to a “roof collapse” in the pulse caused by a weakening of the radiation intensity as the particles pass a receiver.
