摘要： Parallel imaging is performed by a magnetic resonance imaging system provided with a multiple RF coil composed of plural element coils. As part of parallel 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 is larger in the size than the imaging FOV. Using an acquisition FOV specified based on the imaging FOV and the reduction rate, a scan for 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.

摘要： MRI signal data is received individually by multiple element coils. For each channel assigned to each element coil at a positioning image taking time, the collected magnetic resonance signal data is entered into a storage unit. An image is reconstructed from the magnetic resonance signal data stored in the storage unit, by referring the storage unit regarding the channel selected at the positioning image taking time. The reconstructed image is displayed. When a channel selection change command is received, an image is reconstructed using the magnetic resonance signal data stored in the storage unit, by referring to the storage unit regarding the changed channel. The after-change corrected image is displayed.

摘要： In a magnetic resonance imaging apparatus, an image storage unit correlates a reconstructed pre-correction image and a reconstructed post-correction image for each slice position and stores the correlated images. When a display condition related to a reconstructed image of one of either the reconstructed pre-correction image and the reconstructed post-correction image stored in the image storage unit is changed, the changed display condition is also applied to the other reconstructed image.
