BIOLOGICAL MAGNETIC FIELD MEASURING APPARATUS AND PARALLEL PROJECTION METHOD TO BIOLOGICAL MODEL

摘要

PROBLEM TO BE SOLVED: To provide a biological magnetic field measuring apparatus capable of obtaining a current distribution within a cardiac muscle as an appropriate current value on the basis of measured magnetic field data, and a parallel projection method to biological model.

SOLUTION: The biological magnetic field measuring apparatus or the like comprises: an operation means (current value conversion part 85) for deriving a current distribution vector and the size of the current distribution vector by multiplying a magnetic field current conversion coefficient corresponding to a distance between z coordinate points of respective flux meters and the respective z coordinate points of coordinate data constituting a heart model positioned right below the respective flux meters with the change amount in the x direction and the change amount in the y direction of magnetic field components in the z direction in the respective flux meters; and operation means (CAM image generation part 86 and composite image generation part 87) for obtaining composite image data for which the current distribution vector and the size of the current distribution vector are projected in parallel to the respective coordinate points of the coordinate data constituting the heart model from a z direction.
