Abstract :
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.
