摘要： According to some embodiments of the invention, it is provided a method of generating a 3D model of a first denture and of a second denture comprising:
x-ray scanning the first and the second dentures in occlusion conditions to obtain a set of data;
generating, from the obtained set of data, a 3D image of the first and the second dentures in occlusion conditions, the generated 3D image comprising voxels;
classifying each of voxels of the generated 3D image as belonging to the first denture, the second dentures, or space between the first and the second dentures; and
generating, from the classified voxels, a 3D model of the first denture and of the second denture,
wherein classifying a voxel of the generated 3D image is based on characteristics of neighboring voxels in the generated 3D image, according to an iterative analysis of voxels from neighbor to neighbor.-

摘要： An extra-oral dental imaging system comprises an X-ray source (102) and an imaging device (101) suitable for producing multiple frames during at least part of an exposure of an object (200), the imaging device (101) being displaced along a scanning direction (X). A method for creating a cephalometric image of a human skull comprises a step of setting said imaging device (101) with an active area having in an imaging plane a width extending along said scanning direction (X), said width varying along a height direction perpendicular to said scanning direction (X); a step of synchronously displacing the X-ray source (102) and the imaging device (101) along said exposure profile; and a step of registering multiple frames produced by the imaging device (101) during the exposure of said object (200) to be imaged. Using for creating a cephalometric image by digital tomosynthesis.

摘要： The invention concerns a method for obtaining operating parameters for an x-ray CBCT imaging apparatus in view of acquiring a set of data of a patient's maxillofacial region. The method comprises: identifying a patient's maxillofacial first region of interest (ROI1), determining a height of a horizontal plane of said patient's maxillofacial first region of interest (ROI1) when the patient is in an occlusion position or bites a patient positioning accessory, acquiring through a slit-shaped collimator window a first set of data relative to said patient's maxillofacial first region of interest (ROI1) including the horizontal plane using x-ray CBCT imaging, reconstructing an axial CBCT slice comprising the horizontal plane based on the first set of data relative to the patient's maxillofacial first region of interest (ROI1), displaying the reconstructed axial CBCT slice of the patients maxillofacial first region of interest (ROI1) from the acquired first set of data, defining at least partially a second region of interest (ROI2) based on the displayed reconstructed axial CBCT slice of the patient's maxillofacial first region of interest (ROI1) and intersecting the latter, obtaining operating parameters for an x-ray CBCT imaging apparatus based on at least the defined second region of interest (ROI2) in view of acquiring a second set of data including the defined second region of interest (ROI2).

摘要： A method for segmenting a 3D model image of a patient's dentition obtains a first 3D model image of the patient dentition and obtains a first segmentation of the first 3D model image, wherein the first segmentation provides at least a tooth surface contour and a tooth label for one or more teeth of the first 3D model. A second 3D model image of the patient dentition is obtained. Each segmented tooth surface contour of the first 3D model is registered to corresponding tooth surface contour of the second 3D model. A second segmentation of the second 3D model image is obtained according to the registered tooth surface contour, wherein the second segmentation similarly provides at least tooth surface contour and a tooth labeling for one or more teeth of the second 3D model image. The segmented second 3D model image is displayed, transmitted, or stored.

摘要： A composite image (300) is created from a plurality of tomographic slices by creating a plurality of two-dimensional slice images by projecting the slices, dividing each slice image into tiles (302) according to a pattern (304), calculating a focus value for each tile (302) of each slice image, selecting one tile (302) for each position in the pattern having a highest focus measure value, and assembling the composite image (300) from said selected tiles (302).

摘要： This invention concerns an ultrasonic dental imaging probe (1), typically comprising several transducers (4) arranged to operate as a transmitter and a receiver, and in particular arranged to transmit ultrasonic waves at a frequency of at least 10 MHz, and optionally several transducers (4) arranged to operate as a transmitter and a receiver and arranged to transmit ultrasonic waves at a frequency of less than 4 MHz. The transducers are mounted on a flexible support (3), secured to a rigid frame (2) typically in a “U” shape. The invention also concerns a device comprising one such probe.

摘要： An integral collimator for an extra-oral imaging system that includes a lead plate surrounding an elongated fixed slot aperture and includes a unitary body in substantially continuous contact with an outer surface of the elongated lead plate. The unitary body can include a lower portion surrounding the elongated lead plate and an upper portion, where the upper portion includes a protrusion configured to engage a transport mechanism for translation in a direction orthogonal to a path of the x-ray.

摘要： A trophy-includes a first trophy part, a second trophy part, and a coupling that enables the first trophy part and the second trophy part to be coupled to each other. The coupling comprises a rapid-action coupling which lacks a screw thread. The coupling further comprises a screw thread connection that enables the first trophy part and the second trophy part to be coupled to each other. An adapter part is also included for coupling the first trophy part and the second trophy part to each other.

摘要： An extra-oral dental imaging apparatus can obtain a radiographic image of a portion of a head of a patient. Exemplary dental apparatus and/or method embodiments can position a subject for dental radiographic imaging by providing a bitable dental arch mounting apparatus to offset the antero-posterior plane of the dental imaging apparatus and the plane of symmetry of the dental arch mounting apparatus. In one embodiment, the offset can be provided by a tilted dental arch mounting apparatus (e.g., relative to the horizontal).
