Abstract

A magnetic resonance imaging MRI) apparatus, including a signal transceiver; a controller configured to control the signal transceiver to apply a bipolar gradient magnetic field in an aortic direction, the aortic direction being a direction in which an aorta is disposed within an object; and an image processor configured to receive, from the signal transceiver, phase signal data obtained by applying the bipolar gradient magnetic field to the object, acquire motion data representing a first motion corresponding to a heartbeat of the object and a second motion corresponding to a respiration of the object based on the phase signal data, and acquire MRI data based on the motion data.

Description

[0001] This application claims the rights and interests of Korean Patent Application No. 10-2015-0073923 filed with the Korean Intellectual Property Office on May 27, 2015, the disclosure of which is incorporated herein by reference in its entirety. Technical field [0002] The present disclosure relates to a magnetic resonance imaging (MRI) apparatus and method, and more specifically, to an MRI apparatus and method that obtains MR images by using motion information of a subject. Background technique [0003] Magnetic resonance imaging (MRI) equipment uses magnetic fields to capture images of target objects and is widely used for accurate diagnosis of diseases because it displays stereoscopic images of bones, lumbar intervertebral discs, joints, nerve ligaments, etc. at a desired angle. When MRI equipment is used to obtain medical images, the movement of the subject may affect the acquisition of high-quality images. [0004] In order to obtain high-quality magnetic resonance (MRI) i...
