Patent number: 11869918Abstract: A digital quantum dot radiographic detection system described herein includes: a scintillation subsystem 202 and a semiconductor light detection subsystem 200, 200? (including a plurality of quantum dot image sensors 200a, 200b). In a first preferred digital quantum dot radiographic detection system, the plurality of quantum dot image sensors 200 is in substantially direct contact with the scintillation subsystem 202. In a second preferred digital quantum dot radiographic detection system, the scintillation subsystem has a plurality of discrete scintillation packets 212a, 212b, at least one of the discrete scintillation packets communicating with at least one of the quantum dot image sensors. The quantum dot image sensors 200 may be associated with semiconductor substrate 210 made from materials such as silicon (and variations thereof) or graphene. An optically opaque layer 220 is preferably positioned between the discrete scintillation packets, 212a, 212b.Type: GrantFiled: December 15, 2022Date of Patent: January 9, 2024Assignee: Oregon Dental, Inc.Inventor: Leigh E.

Patent number: 10722191Abstract: A method for diagnosis and evaluation of tooth decay comprises: locating in an x-ray image the contour of the dento-enamel junction (DEJ); measuring optical density along contours substantially parallel to and on either side of the DEJ contour; and calculating at least one decay value from the measured optical densities. A method for diagnosis and evaluation of periodontal disease comprises: measuring in an x-ray image a bone depth (BD) relative to the position of the cemento-enamel junctions (CEJs) of adjacent teeth; measuring bone density along a contour between the adjacent teeth; and calculating a crestal density (CD) value from the measured bone density. Calibration standards may be employed for facilitating calculation of the values. A dental digital x-ray imaging calibration method for at least partly correcting for variations of the optical densities of images acquired from the dental digital x-ray imaging system.Type: GrantFiled: December 1, 2017Date of Patent: July 28, 2020Assignee: OREGON DENTAL, INC.Inventor: Leigh E.
