Maximum singlet oxygen concentration at the deepest position in the tumor (3 mm) versus distance to the center of the illumination spot for different irradiances: (a) 100 W/cm2, (b) 150 W/cm2, and (c) 200 W/cm2 in all the pathologies (BCC: nodular basal cell carcinoma; INF: infiltrative basal cell carcinoma; SCC: squamous cell carcinoma) and at 0.1 mm from the pathology surface and different irradiances: (d) 100 W/cm2, (e) 150 W/cm2, and (f) 200 W/cm2.
