Methods and apparatuses for dental images
Described herein are methods and apparatuses to obtain an image, or a set of images, of a patient's teeth from one or more predetermined viewing angles. These methods and apparatuses may include the use an overlay comprising an outline of teeth for each predetermined viewing angle. The overlay may be used for automatically capturing, focusing and/or illuminating the teeth. Also described herein are methods and apparatuses for using a series of images of the patient's teeth including a set of predetermined views to determine if a patient is a candidate for an orthopedic procedure.
1. A method to obtain a series of images of a patient's teeth, the method comprising:
displaying, on a screen of a mobile telecommunications device having a camera, a real-time image based on real-time image data from the camera; and
guiding a user in taking a series of predetermined views of the patient's teeth by sequentially:
indicating on the screen whether the real-time image corresponds to a predetermined view from the series of predetermined views; and
triggering, with the mobile telecommunications device, a capture of an image of the patient's teeth with the camera when the real-time image corresponds to the predetermined view.
2. The method of claim 1 , wherein indicating further comprises superimposing an overlay of an outline of teeth over the patient's teeth on the screen.
3. The method of claim 2 , wherein the overlay corresponds to a patient specific overlay derived from the patient's teeth.
4. The method of claim 2 , wherein the overlay of the outline of the teeth is selected by a trained network that selects the overlay from a family of overlays.
5. The method of claim 2 , wherein indicating is based on determining a difference between an outer perimeter of the patient's teeth and the overlay.
6. The method of claim 2 , wherein indicating is based on contour matching between the overlay and the real-time image data from the camera.
7. The method of claim 1 , wherein indicating is based on edge detection of an outer perimeter of the patient's teeth.
8. The method of claim 1 , wherein triggering is based on a trained network matching the patient's teeth with an acceptable percentage of match.
9. The method of claim 1 , wherein triggering automatically captures the image of the patient's teeth.
10. The method of claim 1 , wherein triggering further provides at least one of a visual, tactile, or audible indicator corresponding to the capture of the image of the patient's teeth.
11. The method of claim 1 , further comprising transmitting the captured image to a remote server to pre-screen the patient for orthodontic treatment, perform a medical evaluation, or a combination thereof.
12. The method of claim 1 , further comprising providing, on the screen, one or more visual cues indicating that the user should move the mobile telecommunications device in one or more particular directions.
13. A non-transitory computer-readable storage medium storing a set of instructions that, when executed by one or more processors of a mobile telecommunications device having a camera, cause the mobile telecommunications device to perform operations comprising:
displaying, on a screen of the mobile telecommunications device, a real-time image from the camera; and
guiding a user in taking a series of predetermined views of a patient's teeth by sequentially:
indicating on the screen whether the real-time image corresponds to a predetermined view from the series of predetermined views; and
triggering, with the mobile telecommunications device, a capture of an image of the patient's teeth with the camera when the real-time image corresponds to the predetermined view.
14. The non-transitory computer-readable storage medium of claim 13 , wherein indicating further comprises superimposing an overlay of an outline of teeth over the patient's teeth on the screen.
15. The non-transitory computer-readable storage medium of claim 14 , wherein the overlay corresponds to a patient specific overlay derived from the patient's teeth.
16. The non-transitory computer-readable storage medium of claim 14 , wherein the overlay of the outline of the teeth is selected by a trained network that selects the overlay from a family of overlays.
17. The non-transitory computer-readable storage medium of claim 14 , wherein indicating is based on determining a difference between an outer perimeter of the patient's teeth and the overlay.
18. The non-transitory computer-readable storage medium of claim 14 , wherein indicating is based on contour matching between the overlay and the real-time image from the camera.
19. The non-transitory computer-readable storage medium of claim 13 , wherein indicating is based on edge detection of an outer perimeter of the patient's teeth.
20. The non-transitory computer-readable storage medium of claim 13 , wherein triggering automatically captures the image of the patient's teeth.
21. The non-transitory computer-readable storage medium of claim 13 , wherein triggering provides at least one of a visual, tactile, or audible indicator corresponding to the capture of the image of the patient's teeth.
22. The non-transitory computer-readable storage medium of claim 13 , wherein the set of instructions further causes the mobile telecommunication device to transmit the captured image to a remote server for pre-screening the patient for orthodontic treatment, performing a medical evaluation, or a combination thereof.
23. The non-transitory computer-readable storage medium of claim 13 , wherein the set of instructions further causes the mobile telecommunication device to provide, on the screen, one or more visual cues indicating that the user should move the mobile telecommunications device in one or more particular directions.
