ABSTRACT:
A method and apparatus are disclosed for automatically delivering a laser beam [30] to an intricate colored region [23] of a treatment area [32], e.g. for laser photocoagulation treatment of venular malformations and other dermatological conditions. Reflected light from the treatment area [32] travels into the delivery console [28] to a color-sensitive detector which signals a control system to permit the laser beam [30] to be delivered to the treatment area [32] only when the beam is focused on a spot having a predetermined color. By scanning over the treatment region, the laser automatically treats only the area having a specified color. Since reflective optics are employed, the reflected light precisely indicates the color of the region where the treatment beam is focused. Reflective optics also provide a smaller and more precise spot size for the treatment beam.
