上原記念生命科学財団, 研究助成金, 2021/06 -2022/05 - Development of contrast enhanced active Doppler ultrasound for non-incision and real time detection of lymph channels
Yoshida Kenji
We proposed a contrast-enhanced active Doppler ultrasound to visualize lymphatic vessels with high sensitivity using a versatile ultrasound system, and showed the ultrasound transmission conditions suitable for the proposed method. We showed that the detection sensitivity of the contrast agent and real-time performance can be improved by the signal processing method using singular value decomposition and by applying high speed imaging with plane wave. These techniques are essential for practical use. Regarding the development of contrast agents for ultrasound and near-infrared fluorescence dual imaging, we confirmed that the characteristics of the phospholipids(phase transition temperature) strongly affect the performance of the contrast agent (fluorescence characteristics, acoustic scattering characteristics, and lifetime). Although we were unable to develop a contrast agent with practical performance, we were able to obtain quantitative data to consider future directions., Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for Scientific Research (B), 2019/04 -2022/03, Coinvestigator, Grant-in-Aid for Scientific Research (B), Chiba University - 超音波による液晶ダイナミクスと高速光計測への展開
