Abstract

光による生体透視イメージングをめざし,近軸散乱光を抽出する方法の改良を試みた.光入射光学系を工夫することにより,近軸散乱光の抽出性能の向上を図った.実験的検討を通し,改良方式により抽出性能を10dB程度向上できることを検証した.また,一般的なコリメート検出系に比べ,散乱体内部伝搬領域を大きく制限して近軸領域に限定できることを確かめた.さらに,散乱体内部吸光度分布の計測を試み,空間分解能よく定量性の高い計測の可能性を示した.

For transillumination imaging of biological body, the previously proposed technique was improved to extract near-axis scattered light efficiently. In experiments, it was verified that extraction efficiency can be improved about 10dB using the newly proposed technique. It was confirmed that the propagation area of scattered light can be largely restricted to the near-axis region. In the measurement of absorption distribution in scatterers, the possibility of accurate absorption measurement with good spatial resolution was demonstrated.
