A magnetic field component in the z direction, vertical to the chest surface of a subject, is measured from two directions, front and back of the chest, and then to calculate the current distributions in the two directions and the distributions of the amplitudes of those current distributions. A three-dimensional standard heart model is created from average data on the cardiac morphology obtained from plural healthy subjects. An optimal position of the model is determined using the coordinates of the sinus node and the coordinates of the left ventricle. Then, a weight coefficient is obtained by front and back current distributions and front and back the distributions of the amplitudes of those current distributions on a set boundary of the model.

摘要： Disclosed herewith is a biomagnetic measurement apparatus capable of displaying electrical excitement as a planispheric map. (First processing 70) A CAM (current arrow map) 71 and another CAM 72 are obtained from magnetocardiogram waveforms measured from both front and back sides of a subject using the data at a point of time of an R-wave peak, then the coordinates of the CAM 72 are inverted in both x and y axis directions to obtain a CAM 73. (Second processing 78) The coordinates of each of the CAMs 71 and 73 are converted to polar coordinates to obtain CAMs 74 and 75 at both front and back sides of the subject. After that, the CAM 74 is adjusted to the CAM 76 in scale to obtain a CAM 76. (Third processing 79) The CAMs 74 and 76 are 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 chart 77 is connected to each another consecutively and smoothly. This is why CAMs at both front and back sides of the subject are displayed on one planispheric chart.
