Abstract: Systems and methods for selecting follicular units in a distribution of follicular units are provided. A selection parameter, such as a distance-related parameter separating the follicular units to be selected, may be used to determine a desired quantity of follicular units to be selected, such as a desired percentage of follicular units to be selected, and to help provide a substantially uniform distribution of selected follicular units. In addition, a characteristic parameter, such as a characteristic distance or characteristic density, may be determined. The characteristic parameter may be used in determining the desired quantity of follicular units to be selected and or may be used for treatment purposes.

Abstract: Methods and systems are provided useful in various procedures, including hair harvesting and implantation, and further including computer-implemented and/or robotic hair transplantation. Methodologies are provided which enable a tool, such as a hair harvesting or a hair implantation tool, to proceed at least under a partial computer control in a selected direction of travel along a donor or recipient area of the patient, as well as changing direction of travel based on desired harvesting and/or implantation criteria.

Abstract: Systems and methods for creating a treatment plan for cosmetic procedures, for example, a hair transplantation procedure, are provided. The treatment plan automatically modifies or generates one or more proposed harvesting or implantation sites within a first hair element based on one or more parameters in one or more second hair elements. Various techniques and methods described in the application provide for improved planning of a natural looking hair.

Abstract: A method of detecting a change in tension of a body surface during a medical procedure is provided. In some embodiments the method may be carried out without additional invasive devices or procedures being required. In one example the methodology is applied when using any type of body surface tensioning device. The tensioning device comprises fiducials that are visible to an image acquisition device. In another example of an embodiment of the current application, the methodology may be applied by attaching fiducials directly to the body surface. The relative motion of the fiducials relative to one another may be utilized to determine a change in body surface tension.

Abstract: Methods and systems are described for hair transplantation and other surgical procedures on a body surface. Specifically, methods and systems for computer-implemented and/or robotic hair transplantation and other surgical procedures, using time constrained image processing techniques are described. In various examples, multiple images of a body surface may be divided into overlapping sub regions for comparison. In various other cases, a percentage of an image of a body surface to be processed may be adjusted based on a time constraint. In some implementations, the output of one of these methods may be used as input for the other method.

Abstract: Methods and systems are provided useful in various procedures, including hair harvesting and implantation, and further including computer-implemented and/or robotic hair transplantation. Methodologies are provided which enable selection of follicular unit harvesting or implanting sites. In various cases, such selection may be made using a lowest and closest method, overlap-based methods, position-based methods, pattern-based methods, and/or a combination of these methods. In various combinations of the methods, the output selection from one of the methods may be used as an input for one of the other methods.
