METHOD FOR CONTROLLING MOVING PATTERN FOR LASER TREATMENT AND LASER IRRADIATION DEVICE USING SAME

Provided are a method of controlling motion pattern for a laser treatment and a laser irradiation apparatus using the same, which can perform the efficient laser treatment. The method of controlling a motion pattern for a laser treatment, the method includes constituting a three-dimensional image of an object; setting a region of therapy on which a laser is irradiated on a surface of the object using the three-dimensional image; setting a guide path passing through the region of therapy; setting a plurality of laser irradiation points arranged on the guide path; and sequentially irradiating the laser on a position corresponding to each of the laser irradiation point among the surface of the object; wherein the guide path includes a first section for entering the region of therapy, a second section for linearly moving at the same speed within the region of therapy, and a third section for reentering to the region of therapy by moving along a curved path while varying the speed outside the region of therapy; and the laser is irradiated at a constant frequency in the second section.
