Magnetic resonance imaging apparatus and magnetic resonance imaging method

摘要

According to one embodiment, a MRI apparatus includes an acquisition unit, a reference section information calculating unit, a positioning unit and an imaging unit. The acquisition unit acquires frames of section image data including a heart from an object with use of magnetic resonance. The reference section information calculating unit calculates spatial positional information of a reference section of the heart based on the frames of the section image data. The positioning unit displays a reference section image of the heart on a display unit and performs positioning of an imaging part for imaging through the displayed reference section image of the heart. The reference section image is calculated from the frames of the section image data based on the positional information of the reference section. The imaging unit images the imaging part set by the positioning.

1. A magnetic resonance imaging (MRI) apparatus comprising:
a static magnetic field generator; gradient magnetic field coils; at least one radio frequency coil; a display; and a control system including at least one control computer coupled to control said display, said gradient magnetic field coils, and said at least one radio frequency coil, said control computer being configured to: control said gradient magnetic field coils and said at least one radio frequency coil to acquire volume image data including a heart from an object; automatically calculate spatial-positional locations of pre-determined anatomical features of the heart based on the acquired volume image data; automatically generate a reference section image of the heart by:
generating a reference section of the heart at a spatial-positional location corresponding to the calculated spatial-positional locations of pre-determined anatomical features of the heart,identifying, from the acquired volume image data, imaging data with spatial-positional locations that correspond to the spatial-positional location of the reference section, andgenerating the reference section image of the heart by forming the identified imaging data into an image; control the display to display the generated reference section image of the heart; set a position of an imaging plane for subsequent cardiac imaging corresponding to a position of the displayed reference section image of the heart; and control said gradient magnetic field coils and said at least one radio frequency coil to acquire a cardiac image of the set imaging plane within the heart of said object.
