SYSTEM AND METHOD FOR GENERATING TREATMENT PATTERNS

1 . A method of treating target tissue, comprising:

selecting a treatment pattern of spots;

generating an aiming beam of aiming light;

translating the aiming beam to form an aiming pattern of the aiming light on the target tissue that indicates the extent of the treatment pattern;

generating a treatment beam of treatment light; and

translating the treatment beam to form the selected treatment pattern of spots of the treatment light on the target tissue.

2 . The method of claim 1 , wherein the aiming beam is translated to form an enclosed aiming pattern of the aiming light on the target tissue in which the treatment pattern is to be confined.

3 . The method of claim 2 , wherein the enclosed aiming pattern outlines the treatment pattern.

4 . The method of claim 2 , wherein the shape of the enclosed aiming pattern comprises any one of a circle, rectangle and ellipse.

5 . The method of claim 1 , wherein the aiming beam is translated to form the aiming pattern that indicates the outer perimeter of the treatment pattern.

6 . The method of claim 1 , wherein the aiming pattern further indicates a center position of the treatment pattern.

7 . The method of claim 6 , wherein the shape of the aiming pattern comprises a crossed line.

8 . A photomedical system for treating target tissue, comprising:

a treatment light source configured to generate a treatment beam of treatment light;

an aiming light source configured to generate an aiming beam of aiming light;

a scanner assembly configured to translate the treatment beam to form a treatment pattern of spots of the treatment light on the target tissue, and translate the aiming beam to form an aiming pattern of the aiming light on the target tissue that indicates the extent of the treatment pattern; and

a controller configured to control the scanner assembly.

9 . The photomedical system of claim 8 , wherein the scanner assembly is configured to translate the aiming beam to form an enclosed aiming pattern of the aiming light on the target tissue in which the treatment pattern is to be confined.

10 . The photomedical system of claim 9 , wherein the enclosed aiming pattern outlines the treatment pattern.

11 . The photomedical system of claim 9 , wherein the shape of the enclosed aiming pattern comprises any one of a circle, rectangle and ellipse.

12 . The photomedical system of claim 8 , wherein the scanner assembly is configured to translate the aiming beam to form the aiming pattern that indicates the outer perimeter of the treatment pattern.

13 . The photomedical system of claim 8 , wherein the aiming pattern further indicates a center position of the treatment pattern.

14 . The photomedical system of claim 13 , wherein the shape of the aiming pattern comprises a crossed line.
