Interactive 3-D examination of root fractures

摘要

A method for 3-D interactive examination of a subject tooth, executed at least in part by a computer, obtains volume image data containing at least the subject tooth and background content adjacent to the subject tooth and displays a first image from the volume data that shows at least the subject tooth and the background content. A portion of the background content in the first image is identified according to a first operator instruction. Tooth content for at least the subject tooth in the first image is identified according to a second operator instruction. At least the subject tooth is segmented from within the volume data according to the first and second operator instructions. The segmented subject tooth is then displayed.

1. A method for 3-D interactive examination of a subject tooth, the method executed at least in part by a computer, comprising:
obtaining volume image data containing at least the subject tooth and background content adjacent to the subject tooth; displaying a first image from the volume data that shows at least the subject tooth and the background content; identifying a portion of the background content in the first image according to a first operator instruction; identifying tooth content for the at least the subject tooth in the first image according to a second operator instruction; segmenting the at least the subject tooth from within the volume data according to the first and second operator instructions; and automatically computing a cutting plane for viewing slices of the tooth that show one or more of a root canal and a tooth fracture; and displaying the segmented subject tooth according to the computed cutting plane.
