  • Patent number: 9529066
    Abstract: A method of collecting magnetic resonance data for imaging an object with a predetermined spin density being arranged in a static magnetic field, comprises the steps subjecting said object to at least one radiofrequency pulse and magnetic field gradients for creating spatially encoded magnetic resonance signals, including at least two settings of spatially encoding phase-contrast gradients differently encoding the phase of said magnetic resonance signals in at least one field of view in a predetermined spatial dimension, acquiring at least two magnetic resonance signals, each with one of said at least two settings of different spatially encoding phase-contrast gradients, and determining at least one mean spin density position of said object along said spatial dimension by calculating the phase difference between said signals. Furthermore, a control device and a magnetic resonance imaging (MRI) device implementing the method are described.

  • Patent number: 8384383
    Abstract: A method for reconstructing a sequence of magnetic resonance (MR) images of an object under investigation, includes the steps of (a) providing a series of sets of image raw data including an image content of the MR images to be reconstructed, the image raw data being collected with the use of at least one radiofrequency receiver coil of a magnetic resonance imaging (MRI) device, wherein each set of image raw data includes a plurality of data samples being generated with a gradient-echo sequence, in particular a FLASH sequence, that spatially encodes an MRI signal received with the at least one radiofrequency receiver coil using a non-Cartesian k-space trajectory, each set of image raw data includes a set of homogeneously distributed lines in k-space with equivalent spatial frequency content, the lines of each set of image raw data cross the center of k-space and cover a continuous range of spatial frequencies, and the positions of the lines of each set of image raw data differ in successive sets of image raw
