  • Patent number: 10420512
    Abstract: In a method for computing MR images of an examination object that performs a cyclic movement, MR signals are detected over at least two cycles of the cyclic movement. In each of these cycles, data for multiple MR images are recorded. Over these cycles, a magnetization of the examination object that influences the MR images approaches a state of equilibrium in a second of these cycles is closer to the state of equilibrium than in a first of these cycles. Movement information for various movement phases of the cyclic movement of the examination object is determined using the MR images from the second cycle, with movement information of the examination object determined for each of the various movement phases. Movement correction of the examination object is carried out in the MR images of the first cycle using the movement information determined in the second cycle.

  • Patent number: 10159424
    Abstract: In a method and medical imaging apparatus, for generating medical image data records, raw data of the examination object are acquired by operation of a medical imaging scanner, a reconstruction algorithm issued for reconstructing a medical image data record on the basis of raw data and of a value of a physiological parameter. At least two medical image data records are created by applying the reconstruction algorithm at least twice to the acquired raw data using a different virtual value of the physiological parameter each time. The at least two medical image data records are provided from the reconstruction computer.

  • Patent number: 9465093
    Abstract: In MR imaging of a predetermined volume segment of a living examination subject, the examination subject is stimulated with a defined stimulation pattern, MR data of the predetermined volume segment, are acquired, and MR images based on the MR data are generated that depend on the stimulation pattern. The predetermined volume segment is an internal organ or muscle tissue of the examination subject.
