911 Study of Dermatologic Laser Therapy for Dilated Blood Vessels Using Fine-Spot Scanning Method
Details
The aim of laser therapy is to destroy the target cells without harming the surrounding tissue. Current approaches to the treatment of lesions often use the delivery of high energy with larger spot sizes compared to the target size, and sometimes unnecessary laser exposure to the adjacent tissue leads to collateral damage. So, we had developed a new type of laser apparatus with a fine laser spot size. To treat vascular lesions on skin, a KTP laser (CW) and a video camera were used. The developed system equipped with a collecting lens assembled by a shrink fitter can focus the laser beam well over a wide scanning width. As a result of the observation of the blood vessel in mouse's pinna after laser beam irradiation, the laser pinpoint irradiation was proved to be effective in the vascular lesions therapy.
