Abstract: For the purpose of effectively suppressing shading generated in an image due to B1 inhomogeneity, there are performed an acquiring step of acquiring magnetic resonance signals simultaneously received at a body coil and a surface coil; a filtering step of applying image-based filtering for suppressing shading due to B1 inhomogeneity to a first image according to received signals from the body coil; a calculating step of calculating a sensitivity of the surface coil based on the image-based-filtered first image and a second image according to received signals from the surface coil; and a correcting step of correcting sensitivity unevenness in the second image using the sensitivity.

Abstract: A magnetic resonance system configured to repeatedly execute imaging sequences each having a first RF pulse for flipping each spin in a region containing blood, and a data acquisition sequence acquiring data of the blood from the region is provided. The magnetic resonance system includes a storage unit configured to store a correspondence relation between a contrast between the blood and a background tissue, a first time taken from the first RF pulse to the data acquisition sequence, and a second time taken from a completion of an imaging sequence to a start of a next imaging sequence, first determining means configured to determine the first time used, and second determining means configured to determine the second time used.

Abstract: With the objective of eliminating variations in signal strength, there is provided a magnetic resonance imaging apparatus in which the process of 90°-exciting and 180°-exciting spins of two slices intersecting each other respectively and receiving a spin echo generated from an intersection thereof is repeated while the intersection is sequentially parallel-moved to a plurality of lines, thereby to generate, based on the received spin echo, a two-dimensional image at the time that the plural lines are seen in a projection direction. In the magnetic resonance imaging apparatus, the lines are set at a matrix in which a phase direction is defined as a row direction and the projection direction is defined as a column direction. A plurality of the lines at which a predetermined number of column intervals are defined as mutual intervals are set in the respective rows. One line is set to each column.
