Laser system and methods for cutaneous treatments and surgery
A laser treatment system includes a sensor configured to detect a targeted therapy region. A processing unit is configured to generate a treatment path that consists of sequentially arranged laser spots to enable the treatment path to fully encompass a targeted therapy region to receive laser therapy. A steering device is alerted to move to a plurality of positions based on the treatment plan generated by the processing unit. A treatment laser provides laser therapy to the plurality of positions and targeted therapy region based on the treatment plan generated by the processing unit.
