Patent ID: 7224163

Claim:
A magnetic resonance imaging apparatus comprising: a plurality of receiving coils for receiving a magnetic resonance signal generated from an object to be examined; means for acquiring examination image data of each of the plural receiving coils from a plurality of slice positions on the object by executing a first pulse sequence using the plural receiving coils while a phase encoding matrix in a k space is thinned out; artifact removing means for removing an aliasing artifact in the examination image using sensitivity distribution data of the receiving coils; and sensitivity image data acquiring means which acquires sensitivity image data by executing a second pulse sequence using the plural receiving coils from first and second slice positions, which have at least one unacquired slice position therebetween, of the plural slice positions on the object, wherein the artifact removing means calculates the sensitivity image data of the receiving coils of the at least one unacquired slice position with a slice interpolation using the sensitivity image data of the first and the second slice positions, and generates the sensitivity distribution data of the plural receiving coils on the slice positions of the examination image data on the basis of the plural sensitivity image data.
