Figure 8
Representative oxygen maps of the area of interest (tumor is in the central part) with corresponding histogram presentation of pO2 level: A - before, B – 24 h and C – 72 h after illumination. Color bars show the pO2 scale from 0 (dark blue) to 100 mm Hg (red). Histograms show the distribution of the pO2 values from the individual pixels, with a distinct shift towards higher oxygenation at 24 h after V-PDT.
