Title:
MRI装置
Document Type and Number:
Japanese Patent JP4607431
Kind Code:
B2
Abstract:
Parallel imaging is performed by a magnetic resonance imaging system provided with a multiple RF coil composed of plural element coils. In the parallel imaging, as part of imaging conditions, a desired imaging FOV and a reduction rate of data acquisition time for the parallel imaging are specified by an operator. An unfolding FOV to which an unfolding scale is assigned is specified. The unfolding scale is larger in value than the reduction rate, thus the unfolding FOV being lager in the size than the imaging FOV. Using an acquisition FOV specified based on the imaging FOV and the reduction rate, a scan for the parallel imaging is performed and images are reconstructed corresponding to the respective element coils. The reconstructed images are unfolded into an unfolding-FOV image at the unfolding scale. An image having the imaging FOV is cut-out, -as a desired final image, from the unfolded image.
