A radiation detector includes a wiring board, a first image sensor, a second image sensor, a first fiber optic plate, a second fiber optic plate, and a scintillator layer. The first fiber optic plate can guide light between a first light entering region and a first light exiting region. The second fiber optic plate can guide light between a second light entering region and a second light exiting region. One side of the first light entering region and one side of the second light entering region are in contact with each other. The first light exiting region is positioned on a first light receiving region. The second light exiting region is positioned on a second light receiving region. One side surface of a first side surface and one side surface of a second side surface exhibit shapes along each other and in contact with each other.

Proposed is an apparatus for marking an irradiation area for a hand-held X-ray device, the device including an upper cover, a lower cover, an X-ray radiation unit, a radiation tube, the apparatus, and a lower support, the apparatus including: a cylindrical member; a reflector; a PCB guide; a PCB; an LED light source; and a fastening screw, wherein light emitted from the LED light source is reflected by the reflector and marks the irradiation area on a subject in front of the reflector.

An intraoral scanner generates 2D images of a dental site and 3D intraoral scans of the dental site. The computing device receives the 2D images of the dental site and the 3D intraoral scans of the dental site from the intraoral scanner, generates a 3D model of the dental site based on the 3D intraoral scans of the dental site, and processes at least one of a) one or more of the 2D images of the dental site, b) one or more of the 3D intraoral scans of the dental site, or c) data from the 3D model of the dental site to identify one or more intraoral areas of interest (AOIs) at the dental site. The computing device determines a dental condition associated with the one or more intraoral AOIs, and determines a manner for scanning the one or more intraoral AOIs.

Disclosed are methods and digital tools for deriving tooth condition information for a patient's teeth, for populating a digital dental chart with derived tooth condition information, and for generating an electronic data record containing such information.

Exemplary method and apparatus embodiments according to the applications can provide calibration of a dental scanning device. An exemplary dental apparatus can include a sensing apparatus including at least one lens and a sensor that is configured to obtain one or more images of at least one surface position, and a calibration target including a spatial light modulator configured to form a prescribed set of calibration patterns, and whose display plane corresponds to the at least one surface position.

The present invention relates to a measurement and data communication device (10) for use in or with an intraoral dental radiology system (100) comprising: an x-ray data management unit (20) having a first communication means (21) for retrieving at least x-ray exposure data, and a processing means (22) for processing at least the retrieved data; an intraoral x-ray generation unit 30) having an x-ray source (31) for exposing at least part of a patient jaw with x-rays; and an intraoral x-ray acquisition unit (40) having a first x-ray sensor (41) for acquiring x-ray image data of at least part of the patient jaw; said device (10) characterized by comprising: a measurement unit (11) for measuring features related to the x-rays used for exposing at least part of the patient, wherein the measurement unit (11) is arranged between the x-ray source (31) and the patient; and a second communication means (12) for transmitting the x-ray exposure data which includes the measured features to the x-ray data management unit (20).

The present invention is an improved barrier-contained radiological sensor holder. In particular, the present invention is directed to radiological sensor holder contained in a barrier sheath to reduce or prevent contamination. The radiological sensor holder preferably comprises a sensor holder at least partly contained within a barrier sheath having a closed end and an open end. The barrier sheath preferably comprises elastomer latex material and the sensor holder preferably comprises an exterior attachment and an interior container, where the exterior attachment presses a portion of the barrier sheath into a gapped attachment port on the interior container. The sensor holder may alternately include an expansion slit along the opposing face. The sensor holder can also have snap on articles for positioning the sensor for posterior, anterior and vertical image capture.

A method of providing an accurate three-dimensional scan of a dental arch area is disclosed. The arch area has two segments and a connecting area between the two segments. The connecting area has homogeneous features. A connecting-geometry tool with at least one definable feature is affixed to the arch area. The definable feature overlays at least part of the connecting area. The arch area is scanned to produce a scanned dataset of the arch area. The definable feature of the connecting-geometry tool on the connection area is determined based on the scanned dataset. The dimensions of the arch area are determined based on the data relating to the definable features from the scanned dataset.

A dispenser of barrier envelopes is formed of a pair of selectively interlocking open-top box-like structures. When interlocked, the pair of structures forms an interior chamber that is configured to store and protect one or more barrier envelopes inside from external contaminants such as viruses, bacteria and/or fungi. The dispenser of barrier envelopes includes a through opening for the purpose of dispensing the one or more envelopes to a user, and a spring in its interior chamber for directing the one or more envelopes toward the through opening.
