| Title | SUPERCONDUCTING BIOMAGNETISM MEASURING APPARATUS |
| Abstract |
PROBLEM TO BE SOLVED: To synchronize time phases of a magnetocardiographic data collected at different times at different locations to the heart beat without installing an electrocardiograph. SOLUTION: This superconducting biomagnetism measuring apparatus detects the phase of the heartbeat from a magnetocardiographic signal detected by a magnetocardiographic sensor 5b and collects the magnetocardiographic data by a superconducting biomagnetism sensor 5a using the detection as a trigger. This constitution can detect the phase of the heartbeat from the magnetocardiographic signal detected by the magnetocardiographic sensor 5b without being affected by the location of the superconducting magnetism sensor 5a, so that, when the magnetocardiographic data are collected by the superconducting magnetism sensor 5a using the detection as a trigger, the phases of the magnetocardiographic data to the heartbeat are synchronized even if the data are collected at different locations at different times. The isomagnetic map of the magnetocardiography is created based thereon. This constitution can dispense with the electrocardiograph so as to eliminate a possibility that the feeble magnetocardiography may be prevented by electrodes and an electric wire of the electrocardiograph worked as noise sources. |
