Table 2.

Tissue death threshold values (TPV_k) given in number of photons absorbed by each photosensitizer per mm³ (×10¹⁸). The data were taken from Table 3 in [8] for (a) 5mg.kg⁻¹ administered dose and 24hrs delay, (b) 100mg.kg⁻¹ administered dose and 6hrs delay, (c) 1mg.kg⁻¹ administered dose and 24hrs delay, and (d) 0.5mg.kg⁻¹ administered dose and 24hrs delay.
