Magnetic resonance imaging system and method

A magnetic resonance imaging apparatus comprising:

• a static magnetic field generation unit configured to generate a static magnetic field in an imaging space;
• a gradient magnetic field generation unit configured to apply a gradient magnetic field pulse to an object to be examined who is placed in the imaging space;
• a high-frequency irradiation unit configured to irradiate a high-frequency magnetic field pulse to the object;
• a reception unit configured to acquire nuclear magnetic resonance signals produced from the object;
• a signal processing unit configured to execute arithmetic processing on the signals acquired by the reception unit for reconstructing an image;
• and
• a control unit configured to control the operation of the high-frequency irradiation unit, gradient magnetic field generation unit and reception unit so as to execute a predetermined pulse sequence, wherein:
• the control unit executes a first sequence for obtaining the data in a predetermined 2-dimensional region in a k-space as the pulse sequence and a second sequence for obtaining the data necessary for imaging reconstruction by irradiating an IR pulse to the object, and corrects the phase of the data obtained in the second sequence using the data of the 2-dimensional region obtained in the first sequence;
• and
• the signal processing unit reconstructs a real component image using the data after being corrected,
• characterized in that the control unit obtains the data of a predetermined 2-dimensional region in the k-space while varying the phase encoding amount upon executing the first sequence.
