20100074403 | PANORAMIC DENTAL RADIOLOGY APPARATUS AND ASSOCIATED METHOD OF USE - 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. | 03-25-2010 |
20100278299 | DENTAL X-RAY APPARATUS AND ASSOCIATED METHOD - A dental X-ray apparatus of the conical-beam digitized-tomography type includes: an X-ray generator emitting an X-ray beam towards an object and provided with a collimation element for collimating the emitted beam; an X-ray sensor having an active surface arranged opposite the generator; wherein the generator and the sensor can rotate simultaneously about a rotation axis, the sensor being oriented so that a longitudinal axis extending from the generator to the sensor through the rotation axis is perpendicular to the active surface of the sensor, the center of the sensor being transversally offset relative to the projection of the axis on the sensor's active surface, the arrangement of the collimation element and the sensor thus offset defining that the collimated beam illuminates the sensor's active surface while leaving a peripheral area of the surface that is faintly illuminated by the collimated beam relative to the rest of the active surface. | 11-04-2010 |
20120039436 | COMBINED PANORAMIC AND COMPUTED TOMOGRAPHY APPARATUS - A combined imaging apparatus for x-ray imaging of a subject in multiple modes has a supporting structure having an extended rotary arm, wherein the rotary arm has a computed tomography detector and a panoramic imaging detector, both mounted adjacently against a movable platen. A detector positioning apparatus is actuable to translate the position of the movable platen to either of at least first and second positions with respect to an x-ray source. The first position disposes the computed tomography detector in the direct path of an x-ray source and the second position disposes the panoramic imaging detector in the direct path of the x-ray source. | 02-16-2012 |
20120243662 | APPARATUS FOR PROVIDING DENTAL RADIOLOGY IMAGE AND METHOD CEPHALOMETRIC - A dental x-ray unit comprising: an X-ray generator adapted to generate an X-ray beam in the direction of a patient's head, means of collimation adapted to confer given dimensions to the generated X-ray beam; a sensor placed facing the generator, receiving the radiologic projection of the collimated beam having irradiated the patient's head and supplying a cephalometric image of the patient's head, characterized in that the device includes: the means to acquire at least one photographic image of the patient's head, the means of automatic control for the means of collimation according to the at least one photographic image so that the dimensions of the collimated X-ray beam are adjusted to the dimensions of the patient's head. | 09-27-2012 |
20120307965 | METHOD FOR GENERATING AN INTRAORAL VOLUME IMAGE - A method for obtaining an intraoral x-ray image determines an initial spatial position and angular orientation of an x-ray source relative to a detector. A first x-ray image is obtained with the x-ray source at the initial spatial position and angular orientation and stored, associating the initial spatial position and angular orientation to the first x-ray image. A sequence repeats that calculates a next spatial position and angular orientation for the x-ray source, provides positional adjustment information between the x-ray source and detector for obtaining a next x-ray image, measures and records the actual spatial position and angular orientation of the x-ray source relative to the detector and obtains and stores the next x-ray image at the measured spatial position and angular orientation, and forms a composite image using image data from the first and from the one or more next x-ray images. | 12-06-2012 |
20130129040 | PANORAMIC DENTAL X-RAY UNIT - A panoramic dental x-ray unit. The unit includes a support rotating about an axis and carrying, in the opposite position, an x-ray source and detector which move following a predetermined trajectory. The unit further includes means for acquiring images of the dental arch of a patient corresponding to the positions of the detector and of the source with respect to the dental arch. There is also provided means for reconstruction of a two portions of a panoramic image corresponding respectively to two disconnected portions of the dental arch, the reconstruction being performed from certain acquired images which each contain at least one piece of information concerning the two disconnected portions of the dental arch. | 05-23-2013 |
20130188629 | ASSOCIATION OF WIRELESS DETECTOR WITH AN IMAGING APPARATUS - A method for directing image data to a dental treatment site wherein a sensor controller is positioned near a programmed radio-frequency identification device at the dental treatment site. A command entry configures the sensor controller to encode and transmit image data content for delivery to a receiving address, according to information obtained from the radio-frequency identification device. A digital sensor that is associated with the sensor controller is positioned in proximity to a subject. Image data is acquired from the digital sensor and transmitted from the sensor controller to a wireless access point, and from the wireless access point to a host computer at the receiving address. The acquired transmitted image data is stored in a computer-accessible electronic memory. | 07-25-2013 |
20130208849 | DENTAL X-RAY APPARATUS AND ASSOCIATED METHOD - A dental X-ray apparatus of the conical-beam digitized-tomography type includes: an X-ray generator emitting an X-ray beam towards an object and provided with a collimation element for collimating the emitted beam; an X-ray sensor having an active surface arranged opposite the generator; wherein the generator and the sensor can rotate simultaneously about a rotation axis, the sensor being oriented so that a longitudinal axis extending from the generator to the sensor through the rotation axis is perpendicular to the active surface of the sensor, the center of the sensor being transversally offset relative to the projection of the axis on the sensor's active surface, the arrangement of the collimation element and the sensor thus offset defining that the collimated beam illuminates the sensor's active surface while leaving a peripheral area of the surface that is faintly illuminated by the collimated beam relative to the rest of the active surface. | 08-15-2013 |
20140071126 | IMAGING APPARATUS FOR DISPLAY OF MAXILLARY AND MANDIBULAR ARCHES - A method for displaying teeth of a patient, generates a three-dimensional model of the patient's teeth and displays the generated three-dimensional model. A displayed image shows a cross-sectional view of the teeth according to the position of a cutting plane extending through the three-dimensional model. The relative position of the cutting plane is adjustable according to an operator instruction. The orientation of the displayed cross-sectional view is determined by the position of the cutting plane. | 03-13-2014 |
20140147803 | SHIELD FOR PATIENT POSITIONING IN EXTRA-ORAL IMAGING - A patient positioning apparatus for an extra-oral imaging system includes a mount for revolving an x-ray source and an imaging sensor panel about a patient's head and a substantially transparent shield suspended from the mount. The shield has a chin support coupled to the shield and comprises a chin rest and a bite element and a forehead support coupled to the shield and comprises a head rest. | 05-29-2014 |
