Abstract: A magnetic resonance imaging (MRI) method and apparatus are provided including a signal acquirer, a resonance frequency acquirer, and an RF driver. The signal acquirer is configured to acquire a free induction decay (FID) signal or an echo signal to generate a magnetic resonance image of a portion of an area of a subject. The resonance frequency acquirer is configured to acquire a resonance frequency of the portion of the area from the acquired FID signal. The RF driver is configured to generate a refocusing RF pulse having the acquired resonance frequency. The signal acquirer, the resonance frequency acquirer and the RF driver are configured to acquire and generate in each of sections of an RF pulse sequence.

Abstract: A method of shimming a magnetic field, includes applying radio frequency (RF) signals to an object, using a transceiver coil, and calibrating phase offsets of magnetic resonance signals acquired from the object through a receiver coil. The method further includes generating RF signals to be applied through the transceiver coil based on magnetic resonance signals acquired from the object through the transceiver coil and the calibrated magnetic resonance signals.

Abstract: Provided are a method and apparatus for obtaining a magnetic resonance imaging (MRI) image of a subject. Typically, MRI image processing that incorporates fat suppression takes a large amount of time to complete. According to various aspects, image processing that incorporates fat suppression may be postponed until MRI data is repeatedly obtained. By doing so, for example, more MRI data may be obtained during a time period of a heartbeat.
