Reliability assessment for blood oxygen saturation levels measured with optoacoustic imaging

摘要

Quantitative optoacoustic (OA) imaging has the potential to provide blood oxygen saturation ( ) estimates due to the proportionality between the measured signal and the blood’s absorption coefficient. However, due to the wavelength-dependent attenuation of light in tissue, a spectral correction of the OA signals is required, and a prime challenge is the validation of both the optical characterization of the tissue and the .
