Publication number: 20240122463Abstract: Various apparatuses are disclosed (e.g., system, device, method, or the like) for guiding the capture and assessing the quality of an image, including dental images. The apparatuses may use trained neural networks to examine images and provide users feedback regarding image quality. The neural networks may be trained based on images within image groups that have been ranked based on perceived image quality.Type: ApplicationFiled: October 16, 2023Publication date: April 18, 2024Applicant: ALIGN TECHNOLOGY, INC.Inventors: Guotu LI, Chao SHI, Chad Clayton BROWN, Christopher E. CRAMER, Phillip Thomas HARRIS, Adam SILL, Will NEVILLE, Ritvik BANSAL

Patent number: 11957541Abstract: Provided herein are systems and methods for scoring a post-treatment tooth position of a patient's teeth. A patient's dentition may be scanned and/or segmented. Raw dental features, principal component analysis (PCA) features, and/or other features may be extracted and compared to those of other teeth, such as those obtained through automated machine learning systems. A classifier can identify and/or output the post-treatment tooth position of the patient's teeth.Type: GrantFiled: December 23, 2022Date of Patent: April 16, 2024Assignee: Align Technology, Inc.Inventors: Guotu Li, Christopher E. Cramer, Chad Clayton Brown, Anton Spiridonov

Patent number: 11962892Abstract: A method of dental treatment may include receiving photos of a person's dentition, identifying a stage of a treatment plan administered to the person's dentition, gathering a three-dimensional (3D) model of the person's dentition corresponding to the stage of the treatment plan, projecting attributes of the 3D model of the person's dentition onto an image plane to get a projected representation of the person's dentition at the stage of the treatment plan, comparing the photos to the projected representation to derive an error image representing the comparison, and analyzing the error image for discrepancies, wherein the discrepancies represent one or more deviations of the person's dentition from the stage of the treatment plan.Type: GrantFiled: July 22, 2021Date of Patent: April 16, 2024Assignee: ALIGN TECHNOLOGY, INC.Inventors: Christopher E. Cramer, Rajiv Venkata, Leela Parvathaneni, Phillip Thomas Harris, Sravani Gurijala, Svetozar Hubenov, Sebastien Hareng, Guotu Li, Yun Gao, Chad Clayton Brown

Publication number: 20240087097Abstract: In a technique to assess the blurriness of an image, an image of a face is received, the image including a depiction of lips. A processing device determines a region of interest in the image, wherein the region of interest comprises an area inside of the lips. The processing device applies a focus operator to the pixels within the region of interest, and calculates a sharpness metric for the region of interest using an output of the focus operator. The processing device determines whether the sharpness metric satisfies a sharpness criterion, and one or more additional operations are performed responsive to determining that the sharpness metric satisfies the sharpness criterion.Type: ApplicationFiled: September 21, 2023Publication date: March 14, 2024Inventors: Chao Shi, Yingjie Li, Chad Clayton Brown, Christopher E. Cramer

Publication number: 20170096612Abstract: A method of applying a lubricant onto a carriage box of a collimator includes: providing a mixture having a lubricant and a solvent; applying an amount of the mixture that includes a predetermined quantity of the lubricant onto a first set of guide rails at a first side of the carriage box; and removing the solvent from the mixture to leave the lubricant adhering to the surface. A kit for lubricating a collimator includes: a container housing a lubricating mixture having a lubricant mixed in a solvent; wherein a quantity of the lubricant is predetermined based, at least in part, on a first surface area of a first set of guide rails at a first side of a carriage box, a second surface area of a second set of guide rails at a second side of the carriage box, or both the first surface area and the second surface area.Type: ApplicationFiled: October 2, 2015Publication date: April 6, 2017Applicant: VARIAN MEDICAL SYSTEMS, INC.Inventors: Stephen J. MOHR, Jonathan EVANS, David BUSECK, Robert KOPELS, Christopher E. BROWN, Steve DOWNEY
