PROBLEM TO BE SOLVED: To speedily adjust a sensor, etc., to an optimum measuring place by providing a shield room with a display means displaying the output of a driving and detecting means driving a superconductive quantum interference device(SQUID) and detecting a signal from the device to easily grasp a magnetic field waveform, magnetic field distribution, etc., measured from a heart. SOLUTION: A SQUID magnetic flux meter, which detects a magnetic field from an examinee lying on one's side in a bed 4 and is held at an extremely low temperature by a cryostat 2, is provided in a shield room 1. This magnetic flux meter is driven be a computer 90 installed outside of the room 1 and the output of the driving and detecting circuit 50 detecting the signal from the magnetic flux meter is collected by the computer 90 to give arithmetic processing. Then, a monitor display 80 displaying a measured magnetic field waveform, an electrocardiogram waveform, the distribution of the magnetic field, the distribution of current, etc., is installed within this room 1. In addition a button 19a for controlling the operation of a SQUID magnetic flux meter and a button 19b controlling the start of data collection are installed. |
