Determining ablation depth and ablation threshold for tissue using CT imaging

Popis výsledku v původním jazyce

Photoablation occurs in laser-irradiated tissue when the laser parameters are adjusted appropriately. This effectively removes the target tissue directly by breaking the molecular bonds and expunging the decomposed fragments. Excimer lasers in pulse mode emit photons carrying enough energy to break the bonds. To analyze the profile of ablation craters and their depth, a new method using CT imaging was developed and verified. Values of depth determined through this method were compared with values obtained by other methods. The aim of our experiments was to determine the ablation depth – the thickness of the layer removed with a single laser pulse in photoablation for different types of tissue. It was determined by dividing the ablation crater depth values obtained through CT imaging by the number of applied laser pulses. Experimentally obtained values of all measured variables are in accordance with values obtained in previous experiments, and with values available in current publications.
