Patent ID: 7587232

Claim:
A magnetic resonance imaging apparatus comprising: an imaging unit which repeatedly executes a multi-slice imaging operation by repeatedly applying a gradient field and a radio-frequency pulse to a subject to be examiner which is place in a static field space and receiving magnetic signals generated in respectively corresponding slice-volumes of the heart of the subject by application of the slice-selecting gradient field and radio-frequency pulse asynchronously with respect to cardiac cycles of said heart; a control unit which controls the imaging unit so as to sequentially change the frequency of the radio-frequency pulse and/or the magnitude of the gradient field so as to achieve repeated multi-slice imaging sequences each repetition of the multi-slice sequence constituting a respectively corresponding dynamic time phase containing one complete multi-slice imaging operation; an imaging reconstruction unit which executes image reconstruction by using magnetic resonance signals received by the multi-slice imaging sequences and obtains a plurality of first images of the heart for each dynamic time phase providing a plurality of slice-volume cross-sections; a processing unit which divides the heart of the subject in the first image in the same dynamic time phase into a plurality of small regions and generates a specific value for each of each pixel values in each said small region of the image of the heart; an image generating unit which generates a first Bull's eye view in a dynamic time phase, the first Bull's eye view providing a Bull's eye two-dimensional developed views of the heart for visualizing a function of each said small region of the heart according to the specific values; and a display unit which displays the first Bull's eye view for each dynamic time phase in a predetermined form.
