A processing device receives, from an image capture device associated with an augmented reality (AR) display, a plurality of images of a face of a patient. The processing device selects a subset of the plurality of images that meet one or more image selection criteria. The selection comprises determining, from the plurality of images, a first image that represents a first position extreme for the face; determining, from the plurality of images, a second image that represents a second position extreme of the face; selecting the first image; and selecting the second image. The processing device further generates a model of a jaw of the patient based at least in part on the subset of the plurality of images that have been selected.

The present invention provides a system for imaging an object comprising: an optical imaging unit for imaging an object on a detection array, the optical imaging unit defining an optical axis and comprising a multicore fiber configured to collect light from the object at an input edge of the multicore fiber and transfer collected light to an output edge of the multicore fiber; a displacing unit configured to shift the input edge of the multicore fiber relatively to the object in a plane substantially perpendicular to the optical axis to obtain a set of shifted images of the object; and an operating unit configured to operate the displacing unit by setting a shifting amplitude to either a first amplitude inferior or equal to the diameter of a core of the multicore fiber or a second amplitude superior or equal to the diameter of the multicore fiber.

An otoscope includes at least one speaker and two microphones. The speaker is configured to generate a stimulus pressure wave and direct a planarized pressure wave toward an ear canal of a patient when the otoscope is at least partially inserted into the ear canal of the patient. The microphones are configured to record the forward stimulus pressure wave as it travels toward the TM and the reverse response pressure wave of the patient as it travels toward the otoscope. The quantitative relationship between the stimulus and the response is the diagnostic measure. The microphones are configured to record the pressure wave, the otoscope is configured to analyze the pressure wave, and the otoscope is configured to display results to a medical professional or user. The speaker and microphones are positioned outside the ear canal of the patient when the otoscope is at least partially inserted into the ear canal.

Methods and apparatuses for taking, using and displaying three-dimensional (3D) volumetric models of a patient's dental arch. A 3D volumetric model may include surface (e.g., color) information as well as information on internal structure, such as near-infrared (near-IR) transparency values for internal structures including enamel and dentin.

An intraoral scanner (90) is disclosed for use with a dental optical coherence tomography system. The scanner has a scanning reflector that is energizable to direct a scanning beam in a raster pattern toward a sample (S) surface. The scanning reflector is further to direct a reflected beam from the sample surface toward a detector (60). The scanning reflector is calibrated to direct the scanning and reflected beams in an open-loop control mode. A dental optical coherence tomography system and a method for calibration of a scanning reflector are also disclosed.

An exemplary apparatus for obtaining data for at least one portion within at least one luminal or hollow sample can be provided. For example, the apparatus can include a first optical arrangement configured to transceive at least one electromagnetic radiation to and from the portion(s). The apparatus can also include a wavelength dispersive second arrangement, which can be configured to disperse the electromagnetic radiation(s). A housing can be provided with a shape of a pill, and enclosing the first and second arrangements.

A method and apparatus for acquiring digital oral cavity data and a tooth scanner control system. The method includes: an oral cavity scanning request is received; scanning data of a target object is acquired based on the oral cavity scanning request, wherein the scanning data includes scanning data of a target scanning rod installed on the target object; the scanning data of the target scanning rod is matched with standard data of the target scanning rod; and the matched standard data of the target scanning rod is utilized for replacing the scanning data of the target scanning rod in the scanning data, and the digital oral cavity data of the target object is obtained.

According to embodiments, disclosed are a device and method for processing an intraoral image. The disclosed method of processing an intraoral image includes displaying the intraoral image based on a scan region of interest having a first size, detecting a predetermined event, based on detecting the predetermined event, adjusting the size of the scan region of interest from the first size to a second size, and displaying the intraoral image based on the scan region of interest having the adjusted second size.

An identification apparatus includes an input interface to which position data including position information of each of a plurality of objects is input, and processing circuitry that is configured to identify at least one object among the plurality of objects based on the position data that is input from the input interface and an estimation model that is trained to estimate a type of each of the plurality of objects based at least on the position data of each of the plurality of objects, the position data including a relative positional relationship which is fixed inside the mouth.

An endoscope handpiece and system may include an angle of view selector, a depressible button, which may be connected to a lock disposed within a port of the endoscopic handpiece. The system may further provide an endoscope, which may be connected to the handpiece via the port and locked in place by the lock.
