Overview

In vivo imaging study demonstrates accurate correction of optical scattering and absorption biases in rodent cerebral cortex, highlighting improved quantification for deep-tissue microscopy.

Key Points

To develop and evaluate an analytical correction model that accounts for wavelength-dependent tissue absorption and scattering in dual-color ratiometric multiphoton microscopy.
Formulated an analytical model incorporating the spectral optical properties of fluorophores and biological tissues.
Evaluated model predictions in the cerebral cortex parenchyma and blood vessel lumens using numerical simulations and in vivo two-photon microscopy in rodents.
Wavelength-dependent absorption and scattering introduced measurement biases of up to ~100% at cortical depths of approximately ~400 μm.
The analytical model successfully corrected these optical biases in parenchymal tissue and venous lumens, but was ineffective in arterioles.
