Abstract: A method and apparatus for capturing a magnetic resonance image in which processes of generating T1 contrast for different regions of an object overlap with each other, thereby obtaining a magnetic resonance image having an improved contrast between different tissues within a short time. Therefore, a time required for obtaining a magnetic resonance image may be reduced, and a magnetic resonance image enabling improved diagnosis of a disease or other abnormal condition may be provided.

Abstract: Provided are apparatuses and methods for magnetic resonance imaging (MRI). The magnetic resonance imaging (MRI) method includes applying radio frequency (RF) pulses to an object in a magnetic field, the RF pulses having different frequency bands for each of at least two types of nucleus in the object; applying predetermined pulse sequences for each type of nucleus to the object; receiving magnetic resonance signals emitted by each nucleus in response to the RF pulses and the predetermined pulse sequences; and generating an image of the object based on the received magnetic resonance signals.

Abstract: A method and an apparatus for generating images are provided. The method includes generating a first sinogram for a state of an object from among states of the object based on a motion of the object, and a second sinogram for the states, based on data obtained from the object, and determining a region of interest (ROI) of the object based on the first sinogram. The method further includes extracting, from the second sinogram, third sinograms corresponding to the ROI, and estimating motion information of the ROI based on the third sinograms. The method further includes correcting the data based on the motion information.
