A computer controlled scanner for the laser treatment of vascular lesions and hyperpigmentation.
A computer controlled scanner has been used with a copper vapour laser for the treatment of vascular lesions and hyperpigmented lesions. The computer controls the position and speed of travel of the laser spot during treatment. The illumination time is adjustable with a minimum of 1 ms. The light from the laser is scanned over the lesion so that the lesion is 'painted in' in a raster-like scan of arbitrary shape and produces a series of parallel lines 0.6 mm apart.
