382 Image Analysis and Modeling in Ophthalmology
Figure 19.9 shows the accumulated thermal damage proles along the pupillary axis,
at time t = 120 sec for calculations with and without a change to the tumor properties.
Computationally, the strategy of changing the properties of the tumor with those of the
vitreous humor simulates the tumor shrinkage as a result of cellular denaturation. This
denaturation is due to the absorption of the laser radiation by a biological tissue.
19.4 Conclusions
The efciency of melanoma treatment using TTT depends largely on the amount of energy
absorbed by the tumor and the surrounding tissues. The calculation of ...
