Determining ablation depth using CT imaging
Original language description
For specific medical applications using laser photoablation, it is necessary to know the ablation depth, i.e. the thickness of the layer removed with a single laser pulse. A new method to determine the ablation crater?s depth was developed using CT imaging; the results produced by this method were compared to results gained by other means and values available in literature. In our experiments a KrF excimer laser with wavelength of 248 nm, pulse duration of 25 ns and repetition frequency set to 5 - 50 Hzwas used to create the ablation craters. Adipose tissue, porcine skeletal and heart striated muscle tissue, which is most akin to human tissue, were used as target tissues. Ablation craters were created using varying repetition frequencies and varying the number of pulses. The craters were then visualized using the PHYWE XR 4.0 RTG unit with a contrast agent (KI) applied to better determine the edges of the crater. The acquired images were evaluated using the ImageJ software, developed
