ABSTRACT:
For the purpose of preventing development of motion artifacts and improving image quality, a first displacement N1of the diaphragm before a scanning section2performs an imaging sequence and a second displacement N2of the diaphragm after the scanning section2has performed the imaging sequence are detected by a body motion detecting section25as displacement caused by respiratory motion of a subject. Thereafter, based on the first displacement N1and second displacement N2of the diaphragm detected by the body motion detecting section25, imaging data is selected as raw data by a raw data selecting section26.Then, based on the imaging data selected as raw data by the raw data selecting section26,a slice image of the subject is produced by an image producing section31.
