Abstract

Noninvasive, accurate monitoring of tissue water content is important for diagnostics and management of edema, dehydration, and other conditions as well as cosmetic applications. We proposed to use the optoacoustic technique for water content monitoring in tissues and demonstrated optoacoustic water detection in tissues in vivo in the 680-1064 nm spectral range. In this work, we demonstrate accurate, high-resolution optoacoustic water monitoring in tissue phantoms and the skin in vivo in the 1370-1650 nm spectral range. Moreover, we identified optimal wavelengths for accurate water monitoring in tissues using layered structures with different water content.
