Abstract
Disclosed is a method for automatically determining the median line of a selected region of a human body so as to simplify complex imaging required hithero for a magnetic resonance imaging apparatus, and, in the method, an artifact of the imaged selected region of the human body is utilized to automatically determine the median line. For example, two artifacts 1010 and 1020 intersecting each other appear from the superior sagittal sinus as shown in FIG. 1 when the direction of phase encoding is changed. By subtracting one of these artifacts 1010 and 1020 from the other and calculating the absolute value of the result of subtraction, the point 1030 of intersection of the artifacts determines the location of the superior sagittal sinus which is the source of apperance of the artifacts, so that the median line can be automatically determined on the basis of the result of determination of location of the superior sagittal sinus.
