    Rapid diffused optical imaging for accurate 3D estimation of subcutaneous tissue features by Shanshan Cai, John Mai, Winn Hong, Scott E. Fraser, Francesco Cutrale

    Published 2025-02-01
    “…We present 3D-multisite diffused optical imaging (3D-mDOI) an approach that combines photon migration techniques from diffuse optical tomography, with automated controls and image analysis techniques for estimating lesion’s depth via its optical coefficients. 3D-mDOI is a non-invasive, low-cost, fast, and contact-free instrument capable of estimating subcutaneous tissue structures volumes through multisite-acquisition of re-emitted light diffusion on the sample surface. …”
