Magnetic resonance imaging apparatus and method
First Claim
1. A magnetic resonance imaging apparatus for acquiring k-space data from a deformable imaging region of a subject and generating image data of the imaging region at the time of being deformed to a predetermined state, based on the acquired k-space data, said magnetic resonance imaging apparatus comprising:
- a gradient coil configured to apply a gradient magnetic field in a phase encoding direction; and
an image data calculation device configured to;
calculate a numeric value for defining a relationship between the imaging region at the time of being deformed to the predetermined state and the imaging region at an nth phase encoding; and
calculate image data of the imaging region at the time of being deformed to the predetermined state, based on the calculated numeric value and the k-space data acquired from the imaging region, wherein the k-space data is acquired along lines that are parallel to a direction along which the imaging region deforms.
