Magnetic resonance imaging apparatus and method of controlling the same

An MRI apparatus comprising:

• a static magnetic field generator configured to apply a static magnetic field to a subject;
• a gradient magnetic field generator configured to apply a gradient magnetic field to the subject the gradient magnetic field generator including a slice-select gradient magnetic field application part, a frequency-encoding gradient magnetic field application part, and a phase-encoding gradient magnetic field application part;
• a radio frequency (RF) coil configured to apply an RF pulse to the subject and receive a signal generated by the subject;
• and
• a processor configured to obtain k-space data on the subject,
• wherein the slice-select gradient magnetic field application part is configured to further apply a slice-select gradient magnetic field to the subject and perform blipped-CAIPI,
• wherein the processor is further configured to determine a phase error of a chemical shift component, compare the k-space data to data in which the phase error of the chemical shift component is reflected, wherein the data in which the phase error of the chemical shift component is reflected is associated with data on a main component and data on a chemical shift component, and determine final data for image restoration based on a result of the comparison, and
• wherein the phase error of the chemical shift component is proportional to a geometric error based on a resonant frequency difference between the main component and chemical shift component in the subject.
