INTEGRATION OF INTRA-ORAL IMAGERY AND VOLUMETRIC IMAGERY

摘要

Systems and methods are described for identifying a sub-gingival surface of a tooth in volumetric imagery data. Shape data is received from a surface scanner and volumetric imagery data is received from a volumetric imaging device. The shape data of the super-gingival portion of a first tooth is registered with the volumetric imagery data of the super-gingival portion of the first tooth to obtain a registration result. At least one criterion is then determined for detecting a surface of the first tooth in the volumetric imagery data of the super-gingival or the sub-gingival portion using the registration result. The surface of the sub-gingival portion of the first tooth is detected in the volumetric imagery data using the at least one criterion.

主权项

1. A method comprising:
receiving, by a computer, shape data of a super-gingival portion of a patient's first tooth; receiving, by the computer, volumetric imagery of the super-gingival portion of the first tooth and volumetric imagery of a sub-gingival portion of the first tooth; registering the shape data of the super-gingival portion with the volumetric data of the super-gingival portion to obtain a registration result using the computer; determining, by the computer, at least one criterion for detecting a surface of the first tooth in the volumetric imagery of the super-gingival or the sub-gingival portions using the registration result; and detecting, by the computer, a surface of the sub-gingival portion of the first tooth within the volumetric imagery of the sub-gingival portion of the first tooth using the at least one criterion.
