Abstract
A CAM (current arrow map)and another CAMare obtained from magnetocardiogram waveforms measured from both front and back sides of a subject using data at a point of time of an R-wave peak, then the coordinates of the CAMare inverted in both x and y axis directions to obtain a CAM. The coordinates of each of the CAMsandare converted to polar coordinates to obtain CAMsandat both front and back sides of the subject. After that, the CAMis adjusted to the CAMin scale to obtain a CAM, and CAMsandare combined. Then, the CAM data at measuring points on each measuring-points-missing radius vector is inserted through an arithmetic processing by interpolation so that CAM data at every measuring point on a planispheric chartare connected to each another consecutively.
