Nonlinearity of optoacoustic signals and a new contrast mechanism for imaging
Abstract Optoacoustic signals behave nonlinearly at light fluences above a few mJ/cm2, which may affect the interpretation and quantification of measurements. It has been proposed that optoacoustic nonlinearity arises from the heat-induced formation of nanobubbles or changes in local thermo-physical...
