Abstract

An imaging method using the velocity change of ultrasonics pulse induced by light illumination was investigated for application to medical diagnosis. The waveforms of echo pulses from the optical absorption region displayed the shift when the light illuminated the sample consisting of a scattering medium and an absorber. The ultrasonic velocity image constructed based on the time shift of echo pulses showed the absorption distribution in a dense scattering medium.
