Abstract

A magnetic resonance imaging (MRI) apparatus and method are disclosed. The MRI apparatus includes: a data acquirer that performs undersampling on MR signals respectively received from a plurality of channel coils included in a radio frequency (RF) multi-coil at non-uniform intervals to obtain a plurality of line data; an image processor configured by A plurality of pieces of K-space data respectively corresponding to the plurality of channel coils are restored using the obtained relationship among the plurality of pieces of line data, thereby restoring an MR image with reduced aliasing artifacts.

Description

technical field [0001] One or more embodiments of the present invention relate to a magnetic resonance imaging (MRI) apparatus and method, and more particularly, to a method for performing undersampling on a plurality of pieces of k-space data obtained by radio frequency (RF) multi-coils to obtain MRI apparatus and method for MR images. Background technique [0002] A magnetic resonance imaging (MRI) device is a device that uses a magnetic field to photograph objects. In addition to showing bones, MRI equipment can also show lumbar intervertebral discs, joints, and neural ligaments in three dimensions at a desired angle. These devices are thus widely used for accurate diagnosis of diseases. [0003] The MRI apparatus obtains magnetic resonance (MR) signals, reconstructs the obtained MR signals into an image, and outputs the image. Specifically, MRI equipment obtains MR signals by using radio frequency (RF) coils, permanent magnets, and gradient coils. [0004] Specifical...
