ABSTRACT:
A first pulse sequence is executed on an imaging portion of an object to be examined using a multiple receiving coils including a plurality of receiving coils to obtain sensitivity images701to703, each of n in number, which is smaller than the number of examination image. When those sensitivity images are calculated, NMR signals are measured only in a low-frequency region of a k space. Next, a second pulse sequence is executed while phase encoding steps are thinned out to acquire examination images704and705, each of m in number (m>n), of the object with each receiving coil. When sensitivity distributions707and708are generated on the basis of sensitivity images701to703, if a sensitivity distribution on a slice corresponding to examination images704and705is not yet measured, it is calculated with a slice interpolation processing on the basis of sensitivity distributions701to703, and an aliasing artifact in examination images704and705are removed using sensitivity distributions707and708with a matrix calculation.
