Figure 12

Illustration of the effect of the tissue inhomogeneity on the detectability. The µT in simulations (A–C) were set to 314 ± N(σ ~ 50) cm−1, 314 ± N(σ ~ 100) cm−1, 314 ± N(σ ~ 150) cm−1, respectively. N(σ) represents a normal random number generator with zero mean and a standard deviation of σ. Detectability visualization of the cells in (A–C), were shown in (D–F), respectively. The higher value of σ reflects the higher level of inhomogeneity in the tissue attenuation coefficient.
