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.

Method and apparatus for capturing magnetic resonance image

A method of magnetic resonance imaging (MRI) includes applying radio frequency (RF) pulses including a plurality of frequency components and a selection gradient to a target to simultaneously excite a plurality of sub-volumes included in each of a plurality of groups, wherein neighboring sub-volumes of all sub-volumes constituting a volume of the target belong to different groups; acquiring magnetic resonance signals from the plurality of sub-volumes by performing 3D encoding on each of the excited sub-volumes; and reconstructing the acquired magnetic resonance signals into image data corresponding to each of the plurality of sub-volumes.

Magnetic resonance imaging system and magnetic resonance imaging method using excited sub-volumes in groups

Provided are high-speed magnetic resonance imaging methods and apparatuses that enable simultaneously obtaining magnetic resonance images with different resolutions. The present embodiments may produce magnetic resonance images with different resolutions more quickly by decreasing time taken to complete scan operations that are performed for producing the magnetic resonance images.

High-speed magnetic resonance imaging method and apparatus

A magnetic resonance imaging (MRI) method and apparatus are provided including a signal acquirer, a resonance frequency acquirer, and an RF driver. The signal acquirer is configured to acquire a free induction decay (FID) signal or an echo signal to generate a magnetic resonance image of a portion of an area of a subject. The resonance frequency acquirer is configured to acquire a resonance frequency of the portion of the area from the acquired FID signal. The RF driver is configured to generate a refocusing RF pulse having the acquired resonance frequency. The signal acquirer, the resonance frequency acquirer and the RF driver are configured to acquire and generate in each of sections of an RF pulse sequence.

Magnetic resonance imaging method and apparatus

Provided are a method and apparatus for obtaining a magnetic resonance imaging (MRI) image of a subject. Typically, MRI image processing that incorporates fat suppression takes a large amount of time to complete. According to various aspects, image processing that incorporates fat suppression may be postponed until MRI data is repeatedly obtained. By doing so, for example, more MRI data may be obtained during a time period of a heartbeat.

Magnetic resonance image (MRI) apparatus and method for obtaining MRI image by modifying motion of subject

A magnetic resonance imaging (MRI) method includes applying a radio-frequency (RF) pulse to a subject including different tissues all including a same type of atomic nuclei to rotate magnetization directions of the atomic nuclei of the different tissues; applying an RF pulse sequence to the subject based on the magnetization directions of the atomic nuclei of the different tissues; and obtaining magnetic resonance signals from the different tissues in response to the RF pulse sequence.
