Abstract

See full text

Disclosed is to provide means for supporting the diagnosis by quantitatively measuring the presence of abnormal condition in the heart of a to-be-tested person and the factor thereof (cause of the disease) from the data of magnetic field strengths measured at a plurality of measuring positions. Feature parameters are automatically picked up from the measured data to calculate Mahalanobis distances thereof, and any abnormal function of the heart is detected relying upon the magnitude thereof. Further, chief factors that cause an increase in the Mahalanobis distance are analyzed to specify the cause of a disease.
