Paper Abstract

The time-resolved detection of laser-induced stress transients makes it possible to detect absorbing structures in turbid media. We used optoacoustic technique for investigation of blood vessels in tissue. The position in depth and the size of absorbers in gel phantoms and vessels in muscle tissue were measured. The acoustic waves were induced by 15-ns 1064-nm pulses of Q-switched Nd:YAG laser. Experimental results have shown that the blood vessels can be visualized at depth up to 10 mm at that wavelength.
