Optimization of Laser Therapy Parameters in Dependence of Spot Size

Abstract Recently, the laser therapy for a treatment of the skin lesions of the vascular origin has gained a substantial development, and progress in the technical area. The vascular lasers, particularly the CANDELA Vbeam Perfecta, which is a part of this research has been equipped by a system of the dynamical cooling, called DCD leading to a higher patient’s comfort during the examination. In the most of the vascular lasers, it was allowed for settings of the pulse length up to 40 ms. By this way, the hematomas are reduced after the treatment, and mostly the skin is only getting red. For a reason of a complexity of the CANDELA Vbeam Perfecta settings, on a demand of the physicians, the user environment has been developed serving for an automatic parameters calculation of the laser therapy, and possibilities of alternative settings for same laser energy. The software environment has been designed in the MATLAB. The SW has been tested in the clinical conditions of the University Hospital of Ostrava.
