Trial Production of Laser Therapy Apparatus using Shrink Fitter
Details
Principles of laser therapy in dermatology are that laser light of a specific wavelength, which is optimally absorbed by the target tissue, is given to the lesion area to increase tissue temperature. Exposure duration that is less than the time necessary for cooling of the target structure, that is, less than the thermal relaxation time of the target is needed. Usually this can be achieved by using very short pulses of light or Q-switched devices. Thermal relaxation time is defined as the time required for a target to cool from the temperature acquired immediately after laser irradiation to half that temperature. If the exposure duration to the laser is greater than the time required for heat diffusion to the surrounding tissue of the target, the thermal damage will be extensive and nonspecific. In this paper we have developed new type of laser therapy apparatus with laser scanning technology.
