Method and system for scanning a laser beam for controlled distribution of laser dosage

A method for distributing an output beam from an intense light source on a body, comprising:

• placing portable beam aiming equipment adjacent a treatment area on the body;
• supplying the output beam to the beam aiming equipment;
• directing the beam aiming equipment to define a propagation axis of the output beam to the body;
• and
• scanning the propagation axis of the output beam at a controlled scan velocity, so that the output beam essentially continuously scans a treatment pattern on the body.

A method for distributing a laser beam from a laser system for treatment of dermatology related disorders on skin, comprising:

• placing portable beam aiming equipment adjacent a treatment area on the skin;
• supplying the output beam to the beam aiming equipment;
• directing the beam aiming equipment to define a propagation axis to the treatment area;
• scanning the propagation axis of the laser beam at a controlled scan velocity, so that the laser beam essentially continuously scans a treatment pattern in a predetermined position within the treatment area on the skin;
• successively repeating the step of scanning so that the laser beam scans a plurality of essentially continuously scanned treatment patterns in respective predetermined positions to fill the treatment area;
• and
• wherein the positions of successively scanned treatment patterns are controlled so that the position of a first sequential treatment pattern is non-adjacent the position of a next sequential treatment pattern.

A laser system for treatment of dermatology related disorders, comprising;

• a laser supplying an output beam;
• a transmissive fiber coupled to the laser and receiving the output beam of the laser;
• a portable treatment head connected to receive the output beam through the transmissive fiber, and having a housing with a light transmissive opening adapted for placement adjacent a treatment area on skin;
• means, mounted with the housing of the treatment head, for directing the output beam through the transmissive opening to a treatment area;
• means, mounted with the housing of the treatment head and coupled with the means for directing, for scanning the output beam in a controlled velocity and direction to define an essentially continuous treatment pattern in the treatment area on the body;
• and
• means, coupled to the laser and the treatment head, for controlling the intensity of the output beam and controlling the means for scanning to establish an essentially constant fluence of radiation in the treatment area.
