説明
We developed a SQUID biomagnetometer system for detecting the magnetic signals evoked from the human cervix within the scope of non-invasive diagnosis of the function of the cervical spinal cord. The system has two main particular features. One is vector SQUID gradiometers and the other is a cryostat optimized for a reclining subject. The vector SQUID gradiometers can maximize the magnetic information acquired from the limited observation area around the neck and the shape of the new cryostat enables a subject to keep his/her position stably in a relaxed manner during the measurement. As a result, we successfully recorded the evoked magnetic fields corresponding to the neural signal travelling along the spinal cords from the necks of human subjects who were given electric stimuli to their thoracic spinal cords.
