  • Patent number: 10712415
    Abstract: In a method and apparatus for recording a magnetic resonance data record in a capture region of an examination object, the capture region being composed of multiple slices, an imaging technique is implemented that uses reference data in the reconstruction of magnetic resonance images, wherein, for all the slices, at least two partial data records are recorded with respectively different contrasts. For thus purpose, a first partial data record is recorded without a preparation pulse and a second partial data record is recorded with a preparation pulse, in particular an inversion pulse. The reference data for at least one first slice for the first partial data record are recorded during a waiting time after the preparation pulse for at least one other, second slice, from which reference data relating to the second partial data record are to be recorded.

  • Patent number: 10684344
    Abstract: Improved motion correction for magnetic resonance imaging is provided. An MR imaging method provides a first sequence of MR images and a second sequence of MR images where: 1) the two sequences are inherently spatially co-registered and synchronous with each other; 2) the first sequence includes signal variation due to one or more causes other than motion or deformation; and 3) the second sequence does not include the signal variation of the first sequence. In this situation, the second sequence can be used to perform motion correction for the first sequence. One example of this approach is Dixon MR imaging, where the water images are the first sequence and the fat images are the second sequence.

  • Patent number: 10677956
    Abstract: A method for measuring one or more properties of a formation includes applying a magnetic field to a subterranean formation using a downhole tool. A radiofrequency signal is transmitted into the subterranean formation that is exposed to the magnetic field. The radiofrequency signal induces a transverse magnetization in the subterranean formation, and the transverse magnetization induces an initial voltage signal in the downhole tool. The initial voltage signal is amplified using a first amplifier in the downhole tool such that the first amplifier outputs a first amplified voltage signal. The first amplified voltage signal is introduced to an input of the first amplifier, such that the first amplifier amplifies the first amplified voltage signal and outputs a second amplified voltage signal.
