Table 3 Diffusion parameter assumption (θ, ρ b ) and calibrated results (D, Flux, K d ) in the Diffusion-Sorption modeling

From: An investigation of the efficacy and mechanism of contrast-enhanced X-ray Computed Tomography utilizing iodine for large specimens through experimental and simulation approaches

Parameters and units Zone 1 (skin) Zone 2 (connective tissue) Zone 3 (muscle issue)
Range (mm) 0-0.7 0.7-0.8 0.8-15
θ (porosity) 0.8 0.8 0.8
ρ b (kg/L) 0.16 0.16 0.265
K d (L/kg) 200 100 200
Initial concentration (mmol/L) 0 0 0
D (m2/s) 1*10−9 1*10−9 1*10−9
Flux (N bc ) (m*mmol/(L*s)) 1.4*10−6   
  1. Notes: ρ b  is the bulk density of different tissues; it was calculated as the mass of the dry tissue divided by total volume. For instance, 1 unit of muscle (i.e., one liter) has a mass of 1.065 kg [31] with dry muscle’s mass 0.265 kg; then ρ b  = 0.265 kg/L
