Table 1.

Summary of tumor stages for 10 animals. The absorption increase due to ICG (Δμ_a) at both tumor and muscle regions for each animal are shown. The unit for Δμ_a is mm⁻¹ and the unit for a tumor size is millimeters. Although animals #7 and #10 has viable tumors, the absorption increase due to ICG is similar to necrotic tumors (highlighted). However, when a priori information is utilized, Δμ_a in the tumor region becomes similar to other viable tumors. The mean values for both groups are also provided together with the standard deviation values.
