Outline of Final Research Achievements

Change of Doppler images with operating speed on probing and surface pressure by probing was analyzed using ultrasonic doppler phantom. Running direction of blood flow in this phantom was only vertical to probing. However, tortuous curve flowing of blood was needed. to reproduce the situation of the living body. It was hard to evaluate blood flow in lymph nodes, which showed tortuous curve flowing , not nonlinearly. It was considered that the phantom with tortuous curve flowing vessel was needed to develop in the future.

Academic Significance and Societal Importance of the Research Achievements

頸部リンパ節の超音波診断において、これまでの研究では考慮されていなかった検査者間の超音波画像の差異について、その差異をなくし平準化した画像を解析した上で数値化された超音波診断基準の作成を行うところに本研究の学術的意義がある。本研究の成果は、超音波検査の経験が浅い検査者においても診断能の向上が図れることができ社会的意義がある。
