Publication number: 20160148370Abstract: A method or computer program for forming a digital model of a patient's teeth. The method includes the steps of: obtaining a plurality of projection images acquired by scanning a negative impression of the patient's teeth using a computed tomographic imaging apparatus; generating, from the plurality of projection images, an air volume model of the air that surrounds the negative impression; defining a transition surface along edges of the air volume model that touch the negative impression; forming the digital model of the patient's teeth according to the defined transition surface; and displaying, storing, or transmitting at least a portion of the digital model of the teeth.Type: ApplicationFiled: March 10, 2014Publication date: May 26, 2016Inventors: Colombe Maury, Xavier Ripoche, Vincent Loustauneau, Sylvie M.

Publication number: 20150297158Abstract: An apparatus for computed tomography imaging of a patient has a rotatable mount that is actuable to rotate about a rotation axis and that supports, at opposite ends an x-ray source and an x-ray detector, wherein the x-ray source is disposed to direct a radiation beam through the patient and toward the detector. A patient positioning apparatus positions the patient relative to the rotation axis. A control logic processor controls rotation of the rotatable mount and acquires image data for the patient at each of a number of angular positions about the rotation axis. A collimator is disposed in front of the x-ray source and controlled by the control logic processor to center the radiation beam, at each of the plurality of angular positions, on a region of interest that is spaced apart from the rotation axis.Type: ApplicationFiled: March 15, 2013Publication date: October 22, 2015Inventors: Sylvie M. Bothorel, Vincent Loustauneau, Colombe Maury, Jean-Marc Inglese

Patent number: 8503604Abstract: A dental radiology apparatus includes an X-radiation generator and a sensor opposite it receiving radiation from the generator. The apparatus produces a panoramic image of an object by displacement of the assembly formed of the generator and the sensor along a given trajectory in a plane, the generator having at least one collimation slit elongated along a z-axis perpendicular to the plane to produce an X-ray beam elongated along this axis in a first mode of operation, the sensor with an array of pixels extending along the Z-axis in correspondence with the beam. The apparatus includes elements for pivoting the sensor by 90° to extend it in a direction parallel to the plane P, switching the generator provided with the collimation slit from the first mode to a second mode of operation to produce an X-ray beam elongated parallel to the direction of the sensor, so that the these positioned sensor is always in correspondence with the beam.Type: GrantFiled: August 24, 2009Date of Patent: August 6, 2013Assignee: TROPHYInventors: Jean-Marc Inglese, Vincent Loustauneau, Sylvie Bothorel
