Patent ID: 7423428

Claim:
A magnetic resonance imaging system comprising: a magnet configured to generate a static magnetic field containing a uniform region whose magnetic intensity is uniform; a couch movable in a predetermined direction passing through the static magnetic field, an object to be imaged disposed on the couch; a reception RF coil; a sensitivity distribution acquiring unit configured to perform a measuring scan with the reception RF coil to acquire sensitivity distributions of the reception RF coil at different positions of the couch with respect to the reception RE coil; a scanning unit configured to perform an imaging scan under a sub-encoding method at an imaging region of the object by transmitting an RF pulse to the object; a reception unit configured to receive through the reception RF coil an echo signal emanated from the imaging scanned region of the object in response to scanning and to process the echo signal to obtain echo data; an image producing unit configured to produce an MR image from echo data obtained in response to the imaging scan; and an unfolding unit configured to unfold the MR image under the sub-encoding method using echo data of the sensitivity distributions.
