  • Patent number: 10314512
    Abstract: In a magnetic resonance method and apparatus for determining an item of deformation information of an examination object that exhibits a cyclical movement within an examination subject, a spatial magnetization pattern is generated in an MR scanner, and MR signals are acquired from the subject during at least two cycles of the cyclical movement, with the spatial magnetization exhibiting differences in a subsequent cycle of the movement compared to an earlier cycle. Segmented subsequent MR images are acquired in a subsequent cycle and the examination object is localized therein. This localization of the examination object is then used to localize the examination object in segmented earlier MR images from the earlier cycle, and the item of deformation information is determined in a spatial direction from the segmented earlier MR images.

  • Patent number: 10317444
    Abstract: The invention relates to a sensor (300) for determining a dielectric property of a medium (205). The sensor (300) has a substrate (301, 302), which has at least one via (203, 204), and a waveguide (12), which is arranged so as to be planar in relation to an upper surface of the substrate (301). The waveguide (12) can be connected to an analysis device (20) by means of the at least one via (203, 204). Furthermore, the waveguide (12) is designed to receive an input signal from the analysis device (20) and to output an output signal to the analysis device (20). When of the waveguide (12) is in contact with a medium (205), properties of the input signal and of the output signal are indicative of the dielectric property of the medium (205). The arrangement of the waveguide (12) so as to be planar in relation to the substrate (301) enables larger measurement ranges and improved measurement accuracies. Furthermore, a compact construction is achieved by the planar structure.

  • Patent number: 10320777
    Abstract: It is proposed that known digital rights management (EDRM: Enterprise Digital Rights Management) be extended such that control over the access to data stored in a cloud remains with the user or originator of the data. This requires the access information to be coordinated between a rights application in the cloud and a rights server in the region of the user (that is to say outside the cloud). A rights policy can be used for fine-grained regulation of the access for users (user groups), computers (client, server) and validity periods. In this context, the access comprises a wide variety of actions which can be performed with the data. In particular, it is advantageous that a server application is provided with (temporally limited) access to a portion of the data in order to index said data, for example, without the server being able to access the complete contents of the data in the process.

  • Patent number: 10317497
    Abstract: In a method and magnetic resonance (MR) apparatus for acquiring MR signals from an examination object an RF excitation pulse is directed into the examination object while activating magnetic field gradients in two different spatial directions, such that a magnetization in the examination object in the two different spatial directions is limited by the RF excitation pulse and the switching of the magnetic field gradients. The magnetization is excited in one of the two spatial directions, of a slice selection direction, in a number of periodic layers, so MR signals are generated in the multiple periodic slices. The MR signals in the multiple periodic layers are read out using multiple reception coils of the MR scanner.

  • Patent number: 10317489
    Abstract: In a method and apparatus for generating a phase-describing map in a firm that is usable to generate magnetic resonance (MR) image data, first and second sets of magnetic resonance echo raw data are acquired from a region of the examination subject, at two different echo times, said first and second sets of magnetic resonance echo raw data originating from two different chemical substance types. First and second image data sets of the defined region are reconstructed respectively from the first and second sets of magnetic resonance echo raw data. An energy function is determined that contains at least one term that places phase-describing values of map points of a phase-describing map in relation to each other dependent on a difference of the respective phase-describing values of the respective map points. The energy function is optimized to obtain an optimized phase-describing map.
