MAGNETIC RESONANCE IMAGING (MRI) APPARATUS AND METHOD OF GENERATING MR IMAGE

摘要

Provided is a magnetic resonance imaging (MRI) apparatus for generating an MR image based on a steady state free procession (SSFP) sequence. The MRI apparatus includes: a radio frequency (RF) controller configured to apply to an object a first RF pulse corresponding to a first slice and a second RF pulse corresponding to a second slice; a gradient magnetic field controller configured to control respective gradient magnetic fields in a first direction corresponding to the first and second RF pulses, from among spatial encoding gradients, to have opposite polarities with respect to each other; a data acquisition unit configured to acquire first and second MR signals corresponding to the first and second slices; and an image processor configured to generate first and second MR images corresponding to the first and second slices, respectively, based on the acquired first and second MR signals.

1. A magnetic resonance imaging (MRI) apparatus for generating an MR image based on a steady state free precession (SSFP) sequence, the MRI apparatus comprising:
a radio frequency (RF) controller configured to apply, to an object, a first RF pulse that corresponds to a first slice and a second RF pulse that corresponds to a second slice; a gradient magnetic field controller configured to control a first gradient magnetic field in a first direction in correspondence with the first RF pulse and a second gradient magnetic field in the first direction in correspondence with the second RF pulse, from among spatial encoding gradients, to have opposite polarities with respect to each other; a data acquirer configured to acquire a first MR signal that corresponds to the first slice and a second MR signal that corresponds to the second slice; and an image processor configured to generate a first MR image that corresponds to the first slice based on the acquired first MR signal, and to generate a second MR image that corresponds to the second slice based on the acquired second MR signal.
