BIOMAGNETIC FIELD MEASURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a biomagnetic field measuring apparatus which displays electrical excitation in a map of a flat spherical graph.

SOLUTION: A CAM 73 is acquired by calculating a CAM (Current arrow map)71 and a CAM 72 respectively from a magnetcardiogram measured from the front and the back sides through using data at the time of the peak position of an R wave and by reversing the x-axis and y-axis directions of the coordinates of the CAM 72 (a first processing 70). A CAM 74 and a CAM 75 on the front and the back sides are acquired by respectively converting the coordinates of the CAM 71 and the CAM 73 to polar coordinates. A CAM 76 is acquired by adjusting the CAM 75 to the scale of the CAM 74 (a second processing 78). The CAM 74 and the CAM 76 are synthesized. CAM data at a missing measure point on a moving radius is inserted by an interpolating operation to make a CAM data at all of the measure points in the flat spherical graph 77 smooth and continuous. Consequently, the CAM of the front and the back sides is displayed on one flat spherical graph (a third processing 79).
