  • Publication number: 20210223341
    Abstract: The present disclosure provides systems, apparatuses, and methods for generating images of the human body by solid-state magnetic resonance imaging. An example method can comprise receiving first imaging data at two or more echo times taken with a first radiofrequency configuration, receiving second imaging data at two or more echo times taken with a second radiofrequency configuration. An example method can comprise generating, based on at least the first imaging data and the second imaging data, two or more k-space datasets. An example method can comprise generating, based on at least the two or more k-space datasets, one or more images. The one or more images can comprise different image contrast.

  • Patent number: 10182739
    Abstract: There is provided a magnetic resonance imaging system using magnetic resonance electrical impedance tomography comprising: a current generation controller configured to control an electric current which is applied to a measurement target; a converter configured to perform analog-digital conversion of data which are obtained by a RF pulse and a gradient pulse applied to the measurement target every repetition time according to a sequence for steady state free precession (SSFP) and, also, by the applied electric current; and an image generator configured to generate an image upon a conductivity distribution of the measurement target by using output data of the converter, wherein the current generation controller controls the electric current to be applied for a preset time within a certain repetition time.
