摘要

研究了一种利用近红外光与超声波相互作用成像的新方法在医学诊断中的应用。将该方法应用于含吸收剂的生物组织(狗胃)。激光二极管的照射使生物组织中吸收器发出的超声回波脉冲发生位移。利用超声回波脉冲的位移重建图像，揭示了隐藏在生物组织中的吸收器的形状。

New imaging method using ultrasonic velocity change caused by light absorption

A new imaging method using the interaction between the near infrared light and the ultrasonic wave was investigated for application to medical diagnosis. The method was applied to a biological tissue (a dog stomach) including absorbers. The ultrasonic echo pulse from absorbers in the biological tissues shifted due to the illumination of laser diode. The image reconstructed from the shift of ultrasonic echo pulses revealed the shape of the absorber hidden in the biological tissue.
