PAS法による生体情報計測基礎実験  [in Japanese] A Fundamental Study of Measurement of Physiological Information by Photoacoustic SpectroscoPy  [in Japanese]

Abstract

本報告では,非破壊分析法として知られている光音響分光法(PAS)による生体深部情報計測に関する実験的検討について述べる.まず,生体ファントムを使用した二層生体モデルによる実験的検討から計測可能深さを明らかにし,さらに,生体から発生する光音響信号が弾性波によるものであることを明らかにすることで,光音響分光法による生体深部計測の可能性を示す.臨床基礎実験として行った冷水負荷実験,運動負荷実験から生体情報として呼吸数,心拍数などが捉えられることを確認した.

A study of the non-invasive measurement system which is based on photoacoustic spectroscopy(PAS) technique for measuring physiological information on human body is presented. From phantom experiments, it is shown that it was possible to measure the physiological in-formation on human body within the depth of about 4mm from the skin surface and the photoacoustic signal detected by a microphone was mainly due to the elastic wave. The clinical experiments using the present system were performed to observe the effects of the exercise and the cold water stress on the heart rate, respiration rate and blood flow dynamics of volunteers.
