Abstract: When an RF pulse sequence is applied to obtain an MR signal, a pulse sequence and a blade pulse sequence that pass a center of a k-space are applied, and thus an over-sampling at the center of a k-space in a short scanning time may be enabled. Therefore, a method for capturing an MR image that is robust against a motion artifact includes applying a radio frequency (RF) pulse sequence; obtaining an MR signal in response to the applied RF pulse sequence; and generating an MR image from the obtained MR signal.
