Publication number: 20260108224Abstract: 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.Type: ApplicationFiled: February 27, 2024Publication date: April 23, 2026Inventors: Qi Wang, Hui Chang, Xiaoguang Zhao, Shiying Sun, Yujia Zhang, Kuo Wan

Publication number: 20060228639Abstract: 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.Type: ApplicationFiled: April 12, 2005Publication date: October 12, 2006Applicant: Xerox CorporationInventors: Eugene Young, David Pan, Robert Pawlik, Robert Tuchrelo, Billy Stojanovski, William Hollenbaugh, Michael Grande, Hui Chang, Mark Mang
