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 TE1 and TE2 in 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 T2
relaxation time is calculated by a T2 relaxation time calculating
section. Then, based on the calculated T2 relaxation time, a T2-weighted
image at the echo time TE2 is 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.
