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: 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.

Abstract: A method of generating an image by using ultrasound waves. The method includes acquiring a first bio-signal of an object, generating at least one first ultrasound frame by using at least one echo signal obtained from at least one first ultrasound wave transmitted to a preset region of interest (ROI) of the object, generating a second ultrasound frame by using an echo signal obtained from a second ultrasound wave transmitted to the preset ROI, and acquiring a second bio-signal of the object at a time when the second ultrasound wave is transmitted to be used for generating the second ultrasound frame, and determining a reference frame from among the generated at least one first ultrasound frame based on the generated second ultrasound frame and the acquired second bio-signal.
