Abstract
An MRI apparatus is provided for obtaining an image of a wide area using a multiple-coil, where a plural number of small receiving coils are arranged such that adjacent coils overlap spatially. An image is picked up while thinning a part of the measured data, such that the low spatial frequency region of the k space is dense and the high spatial frequency region thereof is sparse. The substantial sensitivity distribution of each small receiving coil is determined using data related to the low spatial frequency region, and an image is composed using the sensitivity distribution and the measured data to produce a high resolution image having no aliasing artifact in a short time.
