Abstract: A method obtains main magnetic field information and radio frequency (RF) pulse related information in a magnetic resonance imaging (MRI) system, in which a pulse having a first flip angle and a pulse having a second flip angle are transmitted to a target object at predetermined time intervals. The method includes: obtaining at least one first response signal with respect to the pulse, having the first flip angle, from the target object; obtaining at least one second response signal, with respect to the pulse having the second flip angle, from the target object; and combining the at least one first response signal and the at least one second response signal to obtain the main magnetic field information and the RF pulse related information.

Abstract: A method obtains a magnetic resonance (MR) spectrum of a voxel in a magnetic resonance (MR) image obtained from a magnetic resonance imaging (MRI) apparatus. The method includes configuring a sampling pattern of k-space data; sampling predetermined data from the k-space data based on the configured sampling pattern; and obtaining the MR spectrum of the voxel by using the sampled data.
