  • Publication number: 20260108224
    Abstract: A method for using anatomical landmarks of a balance organ to construct a three-dimensional cephalometric coordinate system includes acquiring a CT image of a craniofacial region to be measured. The anatomical landmarks of the CT image are determined. On the basis thereof, a horizontal plane, and then a coronal plane and a median sagittal-plane plane are determined. The horizontal plane is a plane formed by certain of the anatomical landmarks. The coronal plane is determined using the horizontal plane and anatomical landmarks, and the median sagittal plane is determined using an anatomical landmark and both the horizontal and coronal. An intersection point of the three planes is used as the origin of a three-dimensional cephalometric coordinate system.

  • Publication number: 20070239681
    Abstract: XML table indexes provide a more efficient mechanism for searching data stored in aggregate form. XML table indexes are a set of tables created to project out in column form commonly sought metadata from stored XML documents. By projecting the data includes into column form, queries on the XML documents can be efficiently processed as they can leverage the enhanced functionality provided by the database tables. The XML table indexes may use aliases, partitioning, constraints and other functions to further improve query flexibility and performance.

  • Publication number: 20060228639
    Abstract: Toners including a low melt wax and a carnauba wax are described. The toners include at least one binder, at least one colorant, at least one wax having a melting point of 135° C. or less, and a compatibilizer wax (e.g., carnauba wax). The low melt wax is preferably polyethylene wax. Images may be formed with the toners in an image forming process including steps of depositing the toner onto a latent image of an imaging member to form a toner image, transferring the toner image to an image receiving substrate, and fusing the toner image. During the fusing, the at least one wax and the compatibilizer wax exude from the toner, forming a stripping enhancing layer upon the toner image. Thus, fuser roll stripping performance is enhanced.
