Abstract

A variety of systems and methods are described which enable quantitative information to be extracted regarding automated procedures, including those performed at a high speed that may require a user input, without having to interrupt the procedure. In addition, these systems and methods serve to provide information on one or more parameters of the automated procedure, whereby they may be modified, if required, to improve the automated procedure or the results from such a procedure. The systems and methods provided are especially useful in automated hair transplantation procedures.

First claim

What is claimed is:

1. A method for modifying a parameter of operation of an apparatus for use in an at least partially automated procedure comprising a plurality of repetitive events, the method comprising:
generating a real-time image of a patient body surface where an image-guided apparatus comprising a tool is used to perform an at least partially automated procedure, the at least partially automated procedure comprising a plurality of repetitive events occurring too fast for a user to discern whether a criterion associated with the at least partially automated procedure is met;
generating at least two historic snapshots of the patient body surface based on the real-time image, the at least two historic snapshots allowing to identify whether the criterion associated with the at least partially automated procedure on the patient body surface is met, wherein the timing of the at least two historic snapshots is automatically controlled by a processor such that a first of the at least two historic snapshots comprises an image acquired at a first moment in time after the tool of the image-guided apparatus has penetrated the patient body surface during occurrence of an event of the plurality of repetitive events, and a second of the at least two historic snapshots comprises an image acquired at a second moment in time associated with substantial completion of the event; and
without interrupting the at least partially automated procedure, modifying at least one parameter of operation of the apparatus for a subsequent event of the plurality of the events if the criterion associated with the at least partially automated procedure is not met for the event, as identified from the at least two historic snapshots of the event.

2. The method of claim 1 , wherein modification of the at least one parameter influences the criterion.

3. The method of claim 1 , comprising determining and displaying a value associated with the criterion.

4. The method of claim 1 , wherein the criterion comprises centering of a tool with respect to an object of the at least partially automated procedure.

5. The method of claim 1 , wherein the criterion comprises whether an object of the at least partially automated procedure was damaged during the procedure or elevation of a tool used during the at least partially automated procedure from the body surface.

6. The method of claim 1 , wherein identifying the criterion comprises visual or calculated identification.

7. The method of claim 1 , wherein the first historic snapshot is captured when the tool has penetrated the patient body surface to a maximum depth of penetration, or at a predetermined time interval after activation of the tool.

8. The method of claim 1 , wherein the tool is fully or semi-automated, and the method further comprises controlling movement of the tool at least in part using a mechanical system, electromechanical system, a pneumatic system, hydraulic system, or a magnetic system.

9. The method of claim 1 , wherein modifying is accomplished automatically, the method further comprising registering a value of the criterion and comparing the registered value to a predetermined value, and if the difference between the registered value and the predetermined value is outside an acceptable range, determining the at least one parameter to modify.

10. The method of claim 1 , wherein modifying is accomplished with a user input through a modification interface, the modification interface comprising a keyboard a mouse, a voice or speech recognition device, a laser pointer, touch screen, tablet computer, personal digital assistant (PDA), or a remote user input device.

11. The method of claim 9 , the method comprises prompting the user to accept automatically determined parameter modification and automatically making such modification if the user accepts the determined parameter modification.

12. The method of claim 1 , wherein a value of the criterion comprises a depth that a tool having graduation markings penetrates the body surface, the method further comprising modifying the depth if the number of, or portion of, the graduation markings above the body surface is outside one or more acceptable or desirable limits.

13. The method of claim 1 , wherein the at least partially automated procedure is a hair transplantation procedure, a site making procedure, a tattoo placement or removal procedure, an ablation procedure, a cosmetic injection procedure, an ophthalmic procedure, or procedure for treating dermatological condition.

14. The method of claim 1 , wherein the apparatus comprises a robotic system having the tool operatively coupled to a robotic arm, and the method further comprises controlling movement of the tool under control of program instructions executed by a processor.

15. The method of claim 1 , further comprising clearing one or more of the parameters of operation of the apparatus before entering a new set of parameters.

16. The method of claim 1 , comprising acquiring data at an instant in time.

17. The method of claim 1 , further comprising providing at least another snapshot of the body surface allowing to identify a value of the modified parameter.

18. The method of claim 1 , wherein if a location of a current procedure site is outside a predetermined distance from one or more previous procedure sites, the method further comprises determining whether to modify the at least one parameter of operation of the apparatus for the current procedure if a value of the criterion is outside one or more acceptable or desirable limits.

19. The method of claim 1 , wherein the at least one parameter comprises a tool approach angle of the tool used in performing the at least partially automated procedure.

20. The method of claim 19 , wherein the at least partially automated procedure is a hair transplantation procedure and the method further comprises determining if the tool approach angle needs to be modified based at least in part on a result of comparison of a minimum or maximum approach angle of the tool and an emergence angle of a hair graft.

21. The method of claim 20 , wherein the minimum or maximum approach angle is automatically selected based on an average emergence angle of a plurality of hair grafts in an area on a body surface or is based on an interpolation procedure between correspondingly at least two minimum or at least two maximum approach angles.

22. The method of claim 20 , wherein if the emergence angle of the hair graft is less than the minimum approach angle and a difference between the minimum approach angle and the emergence angle of the hair graft is less than a predetermined value, the tool is oriented at an angle which is substantially equal to the sum of the predetermined value and the emergence angle of the hair graft.

23. A method for determining a need to modify a parameter of an at least partially automated hair transplantation procedure, the method comprising:
processing a real-time image of a surface having an at least partially automated hair transplantation procedure performed thereon;
processing at least one snapshot of the surface, the at least one snapshot identifying a tool approach angle of a tool used in performing the at least partially automated hair transplantation procedure; and
determining if a value of the tool approach angle or a different parameter associated with the at least partially automated hair transplantation procedure is outside one or more acceptable or desirable limits and whether the
