Abstract

We measured optical absorption images of phantoms using our new method that detects ultrasonic velocity change caused by light illumination. The electric scan function of the remodeled diagnostic ultrasonic equipment quickly constructed the ultrasonic velocity change images. The spectroscopic information of phantoms was also obtained from the dependence of ultrasonic velocity change image on the wavelength of the tunable laser used for illumination. It was suggested that our method had the potential to monitor biomarkers used in drug-delivery systems.
