ABSTRACT:
A method for calculating a sensitivity distribution of a receive coil and taking a tomographic image of a subject, based on magnetic resonance signals received by a surface coil in an imaging sequence with a plurality of different echo times TE1and TE2in a reference scan, a plurality of reference images are produced by a first reference image producing section; and based on the plurality of reference images, a T2relaxation time is calculated by a T2relaxation time calculating section. Then, based on the calculated T2relaxation time, a T2-weighted image at the echo time TE2is calculated by a T2-weighted image calculating section, and thereafter, based on the reference image and T2-weighted image at the echo time TE2, a sensitivity distribution is calculated by a sensitivity distribution calculating section. Based on the sensitivity distribution, a tomographic image by an actual scan is corrected by a correcting section.
