| Outline of Final Research Achievements |
By integrating electrical impedance CT technology, magnetic measurement technology, and laser technology, we aimed to develop a system that acquires conductivity distribution in vivo as a tomographic image in a safe, noninvasive, noncontact manner that could not be realized so far. We first proposed a current induced magnetic tomography method, developed a water bath phantom experiment system of 1 kHz 8 channel current induced magnetic tomography, succeeded in imaging the conductivity distribution in aquarium, possibility of current induced magnetic tomography Could be shown. Next, we developed a noncontact current injection device, studied high frequency characteristics of the sensor necessary for integration with a high frequency optically pumped atomic magnetometer, succeeded in high sensitivity observation of magnetic flux density change at 100 kHz.
