Patent ID: 7825662

Claim:
A magnetic resonance imaging (MRI) apparatus comprising: an imaging device configured to perform magnetic resonance imaging in a steady state free precession (SSFP) pulse sequence in which radio frequency (RF) excitation is accomplished by a phase cycling method; and a control device configured to control execution of the phase cycling method by said imaging and to cause said imaging device to: collect data regarding a plurality of frequency regions in a k-space in the SSFP pulse sequence in a first phase series of a plurality of phase series; collect data regarding low frequency regions in the k-space in the SSFP pulse sequence in the remaining phase series of the plurality of phase series; reconstruct an image by Fourier transform of the data regarding the plurality of frequency regions collected in the SSFP pulse sequence in the first phase series; generate frequency data of the k-space by inverse Fourier transform of the image; separate the frequency data into data of low frequency regions in the k-space and data of high frequency regions in the k-space; add data having a value equal to 0 to the separated data of the low frequency regions collected in the SSFP pulse sequence in the first phase series as first substitute data for the data of the high frequency regions; add data having a value equal to 0 to the separated data of the high frequency regions collected in the SSFP pulse sequence in the first phase series as second substitute data for the data of the low frequency regions; add data having a value equal to 0 to the data of the low frequency regions collected in the SSFP pulse sequence in the remaining phase series as third substitute data for the data of the high frequency regions; reconstruct a plurality of low space frequency images based on the low frequency regions to which the third substitute data have been added; reconstruct a plurality of high space frequency images based on the high frequency regions to which the second substitute data have been added; and combine the plurality of low space frequency images and the plurality of high space frequency images multiplied by a scaling factor.
