| Outline of Final Research Achievements |
We constructed a system capable of transmitting and receiving ultrasonic waves to the living tissue under arbitrary conditions at first. In this system, not only ultrasonic observation in the living tissue but also measurement of various substances including the extracted biological specimen is also possible. For the living tissues under each condition, the structural analysis of the internal part of the lymph node developed by the applicant and the degeneration evaluation algorithm at the cell level were applied, and the characteristic acoustic characteristics of each organization were analyzed.
Plurality of ultrasonic probes to be used in conjunction with the above-described system were prepared, and the living tissue measurement was made possible by using an ultrasonic beam suitable for the observation target. In addition, we proposed a robust signal compensation and analytical method considering mixing of noise caused by acoustic wave propagation in the living tissue.
