Magnetic resonance imaging apparatus and method of analyzing images provided thereby

A magnetic resonance imaging apparatus comprising:

• a pulse-applying unit which applies a gradient magnetic field and high-frequency pulses to a subject lying in a static magnetic field;
• a cine-image unit which collects time-series images of an region of interest in the subject and which reconstructs an image from a magnetic resonance signal generated in a subject as the gradient magnetic field and high-frequency pulses are applied to the subject;
• a characterizing-part detecting unit which detects characteristics of the time-series images;
• a motion-analyzing unit which analyzes motion-characteristic values of the characteristics detected by the characterizing-part detecting unit;
• and
• an information-extracting unit which extracts information about a specified time phase, on the basis of the motion-characteristic values;

A method analyzing images provided by a magnetic resonance imaging apparatus configured to generate a static magnetic field, to superpose, on the static magnetic field, a gradient magnetic field generated by a gradient magnetic-field coil, to detect a magnetic resonance signal generated in a subject lying in the static magnetic field and induced from a high-frequency magnetic field emanating from a transmitting coil, and to acquire an image from the magnetic resonance signal, the method comprising:

• collecting time-series images of an region of interest in the subject and reconstructing an image;
• detecting characteristics of the time-series images;
• analyzing motion-characteristic values of the characteristics extracted;
• and
• extracting information about a specified time phase in accordance with the motion-characteristic values.
