Determining ablation depth and laser-tissue interaction
Original language description
The type of the laser beam’s interaction with tissue depends on the configuration of the laser (wavelength, energy density, pulse duration) as well as on the tissue’s parameters. From a biomedical point of view the most interesting ones are the photoablative interactions, which effectively remove tissue via decomposition without excessive heat damage to the remaining tissue. To create an ablation crater the tissue must be exposed to a laser beam with a power density from 107 to 1010 W* cm-2 for 10 to 100 ns, the most common type used for photoablation being excimer lasers. [1] Thickness of the material extracted by a single pulse is called the ablation depth. Knowledge of the depth is key to plan out concrete medical procedures, it enables to precisely ascertain the amount of pulses required. We have developed a new method of measuring the ablation depth using CT imagery of the ablation craters, the results of which we compared to results available in literature [3,4] and values gained through other methods using the same samples.
