Abstract
Laser induced fluorescence of human tissue has been discussed as a tool for control of laser application in surgery for some years. Differences in tissue composition create different spectra, thus leading to a unique identification. We have demonstrated that this method can be combined with the photoablative effect of excimer laser radiation. The irradiated and ablated material fluoresces in a characteristic manner, which can be used to control the further action of the excimer laser. The analysis of the spectrum is performed within 30 ms by computer thus allowing repetition rates of 30 shots per sec corresponding to a cutting speed of 0.5 mm per sec. A Combination of both, recognition of fluorescence spectra and subsequent computer-controlled laser emission leads the way to computer guided surgery (CGS) with resolution in the pm range.
