Abstract: In a method and apparatus for the examination of a predetermined volume portion of an object with a magnetic resonance (MR) fingerprinting procedure, an MR signal curve for voxels of the volume portion is acquired, and a comparison of the MR signal curve of the respective voxel is made with stored MR signal curves in order to determine the stored MR signal curve that conforms most closely to the MR signal curve, with the result of the comparison then being made available as an output. The comparison with the MR signal curve of the voxel is (initially) performed with a specific number of signal points of the MR signal curve. A quality measure is determined with which the quality of the most closely conforming stored MR signal curves is determined. The performance of the comparison for the respective voxel is repeated if the quality measure is below a predetermined quality threshold value, with the number of signal points being first increased by a difference number.

Abstract: Functional and anatomical information are combined in medical imaging. The functional information is treated as a light source illuminating surrounding anatomy, not just along a viewing direction. As a result, rendered images of the anatomy include highlighting or visual lighting queues showing locations of biological activity using global illumination.
Abstract: In a method, a local coil, and an apparatus for magnetic resonance imaging, an examination subject is situated in a patient receiving area of the apparatus, together with at least one marker element. The apparatus is operated to perform a radio-frequency excitation of the at least one marker element, and to read out magnetic resonance signals that are emitted by the at least one marker element. An image data acquisition scanner of the magnetic resonance apparatus is adjusted using the magnetic resonance signals that have been read out. Magnetic resonance image data are acquired from the subject by operation of the adjusted image data acquisition scanner.
Abstract: A method for computer-assisted determination of usage of electrical energy produced by a power generation plant such as a renewable power generation plant is provided. The method uses a plurality of neural networks having a different structure or being learned differently for calculating future energy amounts produced by a power generation plant. To do so, the energy outputs of the power generation plant forecasted by the plurality of the neural networks are used to build histograms. Based on the histograms, energy amounts for different confidence levels describing the likelihood of the availability of the energy amount are determined, and different uses are assigned to different energy amounts. Energy amounts having a higher likelihood of availability in the future are sold at higher prices than other energy amounts.

Abstract: Various embodiments may include a method for monitoring a hot gas region of a gas turbine comprising: monitoring the region using an imaging radar assembly remote from the region, connected to the region with a hollow conductor. The hollow conductor is closed off at a first end proximate the radar assembly. The radar assembly operates outside the closed-off cavity and the second end opens into the region or is shielded against heat but permeable to radar waves passing into the region. The radar is actuated in time intervals wherein at least parts of the hot gas space are detected by the radar assembly repeatedly at the time intervals. The method includes: feeding acquired image data to an evaluation device; evaluating the acquired image data against a predefined maintenance requirement; and triggering a maintenance alarm as a function of the result of the evaluation.

Abstract: In a magnetic resonance imaging (MRI) apparatus and a method for operation thereof, for a specified slice of a subject under examination, which slice is to be excited, an excitation frequency fA+ and fA? is determined for each of two opposite polarities of a slice-selection gradient for an associated RF excitation pulse. In addition, for a specified nominal center frequency f0 of the MRI apparatus, a difference between fA+ and f0 and a difference between fA? and f0 are determined. The polarity is then set such that a smaller of the two differences is achieved.
Abstract: A method for low-speed balancing of a rotor having at least one compressor stage blades assembly includes a row of blades circumferentially arranged with circumferential clearance. Two or more blades are located blades, each having an angular position in the assembly, at which the located blades are maintained. The located blades define sectors. Each sector includes movable blades and sectoral circumferential clearances. The movable blades, for each sector, are circumferentially adjusted such that the sectoral circumferential clearance of the sector moves circumferentially downstream relative to the movable blades with respect to a rotational direction when the assembly is rotated. Relative position of the sectoral circumferential clearances and the movable blades within each sector is maintained by inserts. A measure of unbalance is determined for the rotor in low-speed balancing conditions.
