Abstract

Noninvasive monitoring of blood parameters such as total hemoglobin concentration and saturation (oxygenation) is important for diagnostics in large populations of patients. We developed a novel optoacoustic array for monitoring of these variables in arteries and veins. The array allows for measurements without scanning, reduces the data acquisition time, and minimizes the influence of motion artifacts. The array combines a custom-made fiber-optic delivery system and multiple piezoelectric transducers. We tested the array in vitro and in vivo. The array design and materials allowed for sensitive measurement of optoacoustic signals without distortion and provided real time measurement of these parameters both in vitro and in vivo without scanning.
