Abstract

A computer system and method is disclosed that generates panoramic dental images and related dental charts. The system allows a user to specify which images the system should use for generating the panoramic image. The system then generates a panoramic image. An image-based chart and a graphic-based chart can be generated from the panoramic image. A user can input chart data on the charts using one or more input devices. A user can also select an option to have the system import chart data from an external source and display the data on the charts. Any inputted and imported data are displayed on the applicable chart for the user to view and analyze. A user can toggle between the individual images, the panoramic image, and the charts. A user can overlay one image or chart over the other. A user can also replace an individual image in the panoramic image.

Claims

1. A method comprising:

generating a panoramic dental image in an electronic format, said panoramic dental image illustrating a plurality of teeth;

generating an image-based dental chart from the panoramic image;

wherein the image-based dental chart and the graphic-based dental chart are operable to receive and display data that is input using at least one of a plurality of input devices.

2. The method of claim 1, wherein the step of generating the panoramic dental image comprises:

receiving a plurality of individual dental images;

identifying a series of tooth boundary locations in each of the individual images; and

aligning the individual dental images to a panoramic plane.

3. The method of claim 2, wherein the plurality of individual dental images were captured by a digital camera.

4. The method of claim 2, wherein the plurality of individual dental images were scanned into an electronic format.

5. The method of claim 1, wherein the step of generating the panoramic image includes receiving an existing panoramic dental image.

6. The method of claim 1, wherein the data includes symbols.

7. The method of claim 1, wherein the image-based dental chart and the graphic-based dental chart are operable to retrieve and display external data that is imported from an external source.

8. The method of claim 7, wherein the external source is a dental charting program.

9. The method of claim 1, wherein the at least one of the input devices is an electronic pen.

10. The method of claim 1, wherein the at least one of the input devices is a device that measures gum pocket size.

11. The method of claim 1, wherein the at least one of the input devices is a cavity detection device.

12. The method of claim 1, further comprising:

providing a feature that allows a user to toggle between the panoramic dental image, the image-based dental chart, and the graphic-based dental chart.

13. A method comprising:

receiving a plurality of dental images in an electronic format;

identifying at least one tooth in each of the images;

identifying a series of boundary locations around each tooth;

aligning each of the dental images to a panoramic plane;

generating a panoramic dental image from the aligned images; and

generating at least one electronic dental chart that includes a chart image created from the panoramic dental image, said chart being operable to receive data that was input using at least one of a plurality of input devices, and said chart being further operable to display the data overlaid on top of the chart image.

14. The method of claim 13, wherein said step of identifying at least one tooth in each of the images is performed programmatically.

15. The method of claim 13, wherein said step of identifying at least one tooth in each of the dental images is performed at least in part by a user.

16. The method of claim 13, further comprising:

storing location information for each of the plurality of dental images, said location information associating each of the images with a particular location in the panoramic dental image;

receiving input from a user to select an area of the panoramic dental image;

retrieving location information to determine which of the plurality of dental images is associated with the selected area in the panoramic dental image; and

displaying the particular one of the plurality of dental images associated with the selected area.

17. The method of claim 16, further comprising:

receiving input from a user to replace the particular one of the plurality of dental images with a replacement image.

18. The method of claim 13, wherein the data includes symbols.

19. The method of claim 13, wherein said at least one electronic dental chart is operable to retrieve and display external data that is imported from an external source.

20. The method of claim 19, wherein the external source is a dental charting program.

21. The method of claim 13, wherein the at least one of the input devices is an electronic pen.

22. The method of claim 13, wherein the at least one of the input devices is a device that measures gum pocket size.

23. The method of claim 13, wherein the at least one of the input devices is a cavity detection device.

24. The method of claim 13, wherein said at least one electronic dental chart is a graphic-based dental chart and wherein said chart image includes a graphical outline of each of the teeth in the panoramic image.

25. The method of claim 24, wherein the graphical outline further includes an outline of soft tissue areas and pocket depth.

26. The method of claim 13, wherein said at least one electronic dental chart includes an image-based dental chart.

27. A system comprising:

a business logic routine;

a first computer coupled to the business logic routine, said first computer including at least one of a plurality of input devices, said second computer further including a display device; and

wherein the business logic routine is operable to generate a panoramic dental image from a plurality of dental images, said panoramic dental image illustrating a plurality of teeth;

to generate at least one electronic dental chart that includes a chart image created from the panoramic dental image;

to display the at least one dental chart on the display to a user upon request; and

to receive data input from the user from the at least one of the input devices, said data input including data to be displayed on the at least one dental chart.

28. The system of claim 27, wherein the business logic resides and executes on the first computer.

29. The system of claim 27, wherein the first computer is coupled to a second computer over a network, and wherein the business logic routine resides and executes on the second computer.

30. The system of claim 27, wherein the business logic routine is operable to generate the panoramic dental image by identifying at least one tooth in each of the dental images, by identifying a series of boundary locations around each tooth, and by aligning each of the dental images to a panoramic plane.

31. The system of claim 27, wherein said business logic routine is further operable to retrieve and display external data that is imported from an external source.

32. The system of claim 27, wherein the at least one of the input devices is an electronic pen.

33. The system of claim 27, wherein said at least one electronic dental chart is a graphic-based dental chart and wherein said chart image includes a graphical outline of each of the teeth in the panoramic dental image.
