(A) Imaging schematic of the spatial frequency domain imaging (SFDI) setup. (B) SFDI data processing flowchart: Intensity image at two frequencies (three phase images per frequency) are demodulated and calibrated with reference phantom images (diffuse reflectance) and then fit to a lookup table generated from Monte Carlo simulations to obtain µ_a and µ_s′. (C) Top row: Reduced scattering coefficient before and after photothrombosis, bottom row: percent change from baseline reduced scattering coefficient after photothrombosis.
