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.
