| Research Abstract |
We proposed a new ultrasonic microscope for medical and biological use. The target is placed on a plastic substrate, and ultrasonic signal is transmitted and received across the substrate. In this phase of research, we improved spatial resolution, and observed brain tumor model and cultured glioma cells. As for brain tumor tissue, we succeeded in highlighting the tumor by quantifying" local roughness of acoustic impedance". As for cell size observation, we succeeded in observing morphological change of glioma cells after being exposed to anticancer agent. Finally, we succeeded in three dimensional observation of tumor and cultured cells simultaneously with the observation of cross sectional acoustic impedance image.
