Abstract
Systems and methods for creating a treatment plan for cosmetic procedures, for example, a hair transplantation procedure, are provided. The treatment plan allows user to provide input on a proposed hair element using a free-hand drawing in a two-dimensional plane, and for the proposed hair element to be generated and displayed on a three-dimensional model of a body surface. Various techniques and methods described in the application provide for improved planning of a natural looking hair.
Claims30
A method of planning for transplantation of hair grafts in a body surface, comprising:
- receiving two-dimensional (2-D) user input of a proposed hair element from a free-hand drawing;
- generating, with a use of a processor, and displaying the proposed hair element on a 3-D model of a body surface on a display device;
- and
- automatically generating a plurality of control points based on the proposed hair element on the 3-D model.
A method of automatically creating a plan for a hair whorl on a body surface, comprising:
- identifying a hair boundary curve, the hair boundary curve having a plurality of control points;
- identifying a hair whorl center;
- automatically assigning an initial orientation value to each of the plurality of control points, the initial orientation value based on the orientation of a virtual line from the whorl center to each of the respective plurality of control points;
- and
- automatically generating proposed follicular unit implantation sites within an area outlined by the hair boundary curve based on the plurality of control points and their corresponding assigned initial orientation values.
A method of planning for transplantation of follicular units in a body surface, comprising:
- receiving one or more two-dimensional (2-D) curves;
- automatically assigning at least two control points to each of the one or more curves;
- automatically determining an initial orientation value for each of the control points based on an angle of a tangent to the one or more curves at each respective control point;
- and
- automatically generating proposed follicular unit implantation or harvesting sites based on the at least two control points of the one or more curves and their corresponding automatically assigned initial orientation values.
