Multimodal optical imaging of the oculofacial region using a solid tissue-simulating facial phantom.

ABSTRACT:

Significance

Spatial frequency domain imaging (SFDI) applies patterned near-infrared illumination to quantify the optical properties of subsurface tissue. The periocular region is unique due to its complex ocular adnexal anatomy. Although SFDI has been successfully applied to relatively flat in vivo tissues, regions that have significant height variations and curvature may result in optical property inaccuracies.

Aim

We characterize the geometric impact of the periocular region on SFDI imaging reliability.

Approach

SFDI was employed to measure the reduced scattering coefficient ( μs' ) and absorption coefficient ( μa ) of the periocular region in a cast facial tissue-simulating phantom by capturing images along regions of interest (ROIs): inferior temporal quad
