Apparatus for imaging and treatment of skin of subject

An apparatus for imaging and treatment of skin of a subject, the apparatus comprising:

• a frame configured to circumscribe a target region of the skin of the subject, the frame having a first end and a second end opposite to the first end;
• an imaging branch contained in the frame, the imaging branch having an imaging path and configured to generate an image of the target region of the skin that is in proximity to the first end of the frame;
• and
• a laser branch contained in the frame, the laser branch having a laser path and configured to radiate electromagnetic rays from the second end of the frame towards the first end of the frame for treatment of the target region of the skin, wherein the laser branch is adapted to convert a shape of a beam of electromagnetic rays by:
• radiating a circular beam of electromagnetic rays at the second end of the frame, and
• outputting a polygonal beam of electromagnetic rays at the first end of the frame for treatment of the target region of the skin of the subject,
• wherein the laser branch is configured to generate a corresponding polygonal treatment spot based on the polygonal beam of electromagnetic rays.

A method for imaging and treatment of skin of a subject using the apparatus of claim 1, the method comprising:

• previewing, by a user, images of the target region of the skin generated by the imaging branch of the apparatus;
• adjusting one or more laser treatment parameters of the laser branch based on the previewed images;
• adjusting at least one of a size or a shape of a polygonal treatment spot by changing a distance between a static lens unit and a dynamic lens unit of a laser lens assembly;
• and
• performing an imaging process or a treatment of the skin of the subject according to the adjusted laser treatment parameters and/or adjusted polygonal treatment spots.
