Abstract

A magnetic resonance imaging (MRI) device and a control method thereof reduce the preparation time for MRI photographing a patient. A patient table has a transfer unit for moving a patient inside the magnet assembly. A fixing unit includes a signal transmitting unit for transmitting a signal such as an optical signal, an ultrasound signal or an RF signal. A signal receiving unit is installed on a diagnosis area of the patient or a radio frequency (RF) coil attached to a diagnosis area of the patient, and a patient position determination system calculates position information of the diagnosis area of the patient or the RF coil if the signal receiving unit detects a signal output from the signal transmitting unit when the transfer unit transfers the patient to inside the magnet assembly and to transfer the diagnosis area of the patient to an optimum photographic area inside the magnet assembly (i.e. the isocentre of the magnet assembly) based on the position information.

Description

technical field [0001] The present invention relates to magnetic resonance imaging, and more particularly, to a magnetic resonance imaging apparatus for diagnosing various diseases by using magnetic resonance images and a control method thereof. Background technique [0002] In general, medical imaging devices provide images obtained from a patient. Medical imaging devices may include ultrasonic diagnostic equipment, tomographic equipment, magnetic resonance imaging equipment, and medical diagnostic equipment. In general, compared with other medical imaging devices, magnetic resonance imaging equipment works under relatively less harsh conditions when taking pictures of patients, and at the same time provides images with superior contrast of soft tissues of the human body and various types of diagnostic information. It has a high status in the diagnostic technology of medical images. [0003] In general, a magnetic resonance imaging apparatus includes an imaging device tha...
