Abstract

Claims (48)

1. A system for contactless registration comprising:

a processor;

a patient reference frame;

a reference frame adapter configured to selectively attach to the patient reference frame, wherein the reference frame adapter includes at least one aperture configured to receive a pin configured to pass through the at least one aperture and is received by a second aperture in the patient reference frame; and

a memory storing data for processing by the processor, the data, when processed, causes the processor to:

receive a first image of a region of a patient;

receive a second image of the region of the patient, wherein the second image includes the patient reference frame and the reference frame adapter, positioned near the region of the patient;

use an image processing algorithm to register the second image to the first image based on the reference frame adapter, wherein the image processing algorithm comprises a machine learning model trained using image data, and wherein registering the second image to the first image comprises determining information about an anatomical element and/or the patient reference frame in the first image and the second image; and

perform a surgical task based on the determined information about the anatomical element and/or the patient reference frame.

2. The system of claim 1 , wherein the reference frame adapter includes at least one reference marker disposed on a surface of the reference frame adapter.

3. The system of claim 1 , wherein the patient reference frame includes at least one reference marker disposed on a surface of the patient reference frame.

4. The system of claim 1 , wherein the at least one aperture included in reference frame adapter is threaded, and wherein the pin is threaded.

5. The system of claim 1 , wherein the reference frame adapter covers at least a portion of the patient reference frame.

6. The system of claim 1 , wherein the second image comprises a 3D scan and the region of the patient comprises a face of the patient.

7. The system of claim 1 , further comprising a navigation system configured to track the patient reference frame, wherein the memory stores further data for processing by the processor that, when processed, causes the processor to:

correlate a pose of the reference frame adapter with a pose of the patient reference frame; and

track the patient reference frame.

8. The system of claim 7 , wherein the reference frame adapter is removed from the patient reference frame after the second image is registered to the first image.

9. A system for contactless registration comprising:

a processor;

a patient electromagnetic (EM) tracker;

an EM reference frame adapter configured to selectively attach to the patient EM tracker, wherein the EM reference frame adapter includes at least one aperture configured to receive a pin configured to pass through the at least one aperture and is received by a second aperture in the patient EM tracker; and

a memory storing data for processing by the processor, the data, when processed, causes the processor to:

receive a first image of a region of a patient;

receive a second image of the region of the patient and the patient EM tracker positioned near the region of the patient; and

use an image processing algorithm to register the second image to the first image based on the EM reference frame adapter, wherein the image processing algorithm comprises a machine learning model trained using image data, and wherein registering the second image to the first image comprises determining information about an anatomical element and/or the patient EM tracker in the first image and the second image; and

perform a surgical task based on the determined information about the anatomical element and/or the patient EM tracker.

10. The system of claim 9 , wherein the EM reference frame adapter includes at least one reference marker disposed on a surface of the EM reference frame adapter.

11. The system of claim 9 , wherein the at least one aperture in the EM reference frame adapter is threaded.

12. The system of claim 9 , wherein the second image comprises a 3D scan and the region of the patient comprises a face of the patient.

13. The system of claim 9 , further comprising a navigation system configured to track the patient EM tracker, wherein the memory stores further data for processing by the processor that, when processed, causes the processor to:

correlate a pose of the EM reference frame adapter with a pose of the patient EM tracker; and

track the patient EM tracker.

14. The system of claim 9 , wherein the EM reference frame adapter is removed from the patient EM tracker after the second image is registered to the first image.

15. A system for contactless registration comprising:

a navigation system configured to track a patient reference frame, wherein the patient reference frame includes a reference frame adapter configured to selectively attach to the patient reference frame, wherein the reference frame adapter includes at least one aperture configured to receive a pin configured to pass through the at least one aperture and is received by a second aperture in the patient reference frame;

a processor; and

a memory storing data for processing by the processor, the data, when processed, causes the processor to:

receive a first image of a region of a patient;

receive a second image of the region of the patient and the reference frame adapter and the patient reference frame positioned near the region of the patient;

use an image processing algorithm to register the second image to the first image based on the reference frame adapter, wherein the image processing algorithm comprises a machine learning model trained using image data, and wherein registering the second image to the first image comprises determining information about an anatomical element and/or the patient reference frame in the first image and the second image; and

cause the navigation system to track the patient reference frame.

16. The system of claim 15 , wherein the reference frame adapter includes at least one reference marker disposed on a surface of the reference frame adapter.

17. The system of claim 15 , wherein the patient reference frame includes at least one reference marker disposed on a surface of the patient reference frame.

18. The system of claim 15 , wherein the at least one aperture in the reference frame adapter is threaded and the pin is threaded.

19. The system of claim 15 , wherein the reference frame adapter covers at least a portion of the patient reference frame.

20. The system of claim 15 , wherein the memory stores further data for processing by the processor that, when processed, causes the processor to:

correlate a pose of the reference frame adapter with a pose of the patient reference frame.
