  • Method of determining a gradient impulse response function during execution of a magnetic resonance imaging or spectroscopy sequence
    Patent number: 10379190
    Abstract: A method of determining an actual gradient impulse response function during execution of a magnetic resonance (MR) imaging or spectroscopy sequence, wherein a main magnetic field is generated in a sample region of an MR apparatus by means of a main magnet and wherein superimposed time dependent gradient fields and radiofrequency fields in a first RF band are generated in the sample region according to a first MR sequence for forming images or spectra, the gradient fields being generated by gradient forming means of the MR apparatus operated according to a gradient forming sequence part of said first MR sequence, the MR apparatus further comprising at least one magnetic field probe.
    Type: Grant
    Filed: May 12, 2016
    Date of Patent: August 13, 2019
    Assignee: Eidgenossische Technische Hochschule (ETH) ETH Zentrum
    Inventors: Bertram Wilm, Christoph Barmet, Klaas P. Prussmann
