Fig. 4: The simulation results of NIR fluorescence imaging through adipose tissue via the Monte Carlo method.
From: High-contrast in vivo fluorescence imaging exploiting wavelengths beyond 1880 nm
a Reduced scattering spectra of adipose tissue within 600–2200 nm and its fitted curve. b Absorption spectra of adipose tissue within 600–2200 nm. c Simulated fluorescence images of a line source passing through the adipose tissue of 1, 2 and 3 mm thicknesses within the 900–1100, 1100–1300, 1300–1400, 1400–1500, 1500–1700, and 1700–2080 nm windows. d SBR analysis of the simulation results at different depths. n = 3 positions were randomly selected for analysis, data are presented as mean ± SD. e SSIM analysis of the simulation results at different depths.
