  • Magnetic resonance imaging
    Patent number: 10401453
    Abstract: A method of acquiring magnetic resonance imaging (MRI) data from an MRI scan of an object includes generating a number of excitation sequences by, in order: generating an excitation pulse, generating an imaging magnetic field gradient, and generating a spoiler magnetic field gradient. MRI data is acquired during the generation of the spoiler magnetic field gradients. The spoiler magnetic field gradients are selected such that, during each excitation sequence, substantially the same k-space trajectory is traversed during the generation of the spoiler magnetic field gradient.
    Type: Grant
    Filed: September 22, 2017
    Date of Patent: September 3, 2019
