Techniques are provided for x-ray sensing for intraoral tomography. A methodology implementing the techniques according to an embodiment includes detecting an x-ray pulse based on energy received at one or more pixels of a pixel array. The method also includes integrating the energy received at each of the pixels of the array of pixels, in response to the detection, wherein the energy received at each of the pixels is associated with the x-ray pulse. The method further includes multiplexing readouts of analog signals from the array of pixels into two or more parallel channels. The method further includes simultaneously converting (or otherwise in parallel) the analog signals of each of the channels into digital signals and storing the digital signals in memory as frames of data. The method may further include, for example, transmitting the frames of data from the memory, over a Universal Serial Bus, to an imaging system.

An intra-oral imaging system includes an imaging device and a control device. The imaging device includes an imager, a controller, and a case in which the imager and the controller are housed. The imager performs imaging detection for detecting radiation in order to acquire an image of an object and monitoring detection for detecting radiation in order to monitor the dose of radiation. The controller transmits an imaging signal and a monitoring signal to the control device, the imaging signal acquired by the imaging detection and the monitoring signal acquired by the monitoring detection. The control device receives the imaging signal and the monitoring signal, and transmits a control command to the controller, the control command generated based on the monitoring signal. The controller controls the imager according to the control command.

An intra-oral imaging device includes: an imager that detects radiation transmitted through an object while being placed in an oral cavity; and a controller that controls the imager while being placed outside the oral cavity. The imager includes an image sensor including a plurality of pixels for acquiring an image of the object. While power is being supplied to the controller, the controller supplies power to the image sensor in an imaging period during which the image sensor performs imaging and stops supplying the power to the image sensor in a standby period during which the image sensor is on standby.

Systems and methods for intraoral scanning include determining, by an appointment management system, a condition that dental impressions have not been received from a user within a threshold time period where the user was provided with an in-home dental impression kit, generating and communicating a message to the user based on the condition where the message prompts the user to schedule an appointment at an intraoral scanning site, receiving a request to schedule an appointment at the intraoral scanning site where the intraoral scanning site has an intraoral scanner configured to conduct an intraoral scan of a mouth of the user, and conducting the intraoral scan using the intraoral scanner at the intraoral scanning site where the intraoral scan generates three-dimensional data of the mouth of the user.

The invention relates to a dental x-ray imaging system for producing intraoral x-ray images, in particular of dental patient tissue, with the aid of an intraoral x-ray sensor, which can be placed in the oral cavity in the beam path of an x-ray emitter positioned outside the oral cavity, wherein the x-ray imaging system is configured to record two or more temporally sequential individual x-ray images and to create an overall x-ray image from said individual images in such a way that the results of the exposures of the x-ray images are combined and a motion occurring between and/or during the sequential individual x-ray images is compensated.

An intraoral imaging apparatus for tomosynthesis imaging has an x-ray source having a primary collimator that defines boundaries of a radiation field. A transport apparatus translates the x ray source along a path for tomographic imaging. An intraoral x-ray detector defines an imaging area for the radiation field. A positioning apparatus correlates the position of the intraoral detector to the position of a secondary collimator. One or more radio-opaque markers provided on a detector attachment is coupled to the detector, the one or more markers configured to condition acquired x-ray images to relate the spatial position of the intraoral x-ray detector to the x-ray source position, wherein the one or more markers are disposed within the defined imaging area. A control logic processor accepts image data from the detector and determines the relative location of the source with respect to the detector according to detected marker position.

The invention concerns a device for obtaining an occlusal registration of a patient; a method for obtaining an occlusal registration of a patient; and a method for dental procedure planning, such as dental implant planning. Radiopaque markers are advantageously applied to improve the devices, methods, and outcomes related to dental procedures.

A method for visualizing patient dentition acquires a contour image of patient dentition and segments the contour image to identify one or more segmented teeth. At least one deciduous tooth among the one or more segmented teeth is identified. A virtual model of a target dentition arrangement of the patient dentition is generated, wherein the at least one deciduous tooth is replaced by a replacement permanent tooth.

Techniques are provided for x-ray onset detection for an intraoral dental sensor. A methodology implementing the techniques according to an embodiment includes calculating a plurality of superpixel values for each of a plurality of rows of detector pixels of a sensor. Each of the superpixel values is based on a sum of pixel values of a set of pixels associated with the superpixel value, the set of pixels selected from the detection row of a current frame of the sensor. The method also includes calculating a difference between each of the superpixel values and a corresponding stored superpixel value generated from a previous sensor frame and determining if the differences exceed a superpixel threshold value. The method further includes incrementing a hit counter in response to the determination and generating a detection signal if the hit counter exceeds a hit count threshold, otherwise proceeding to process the next detection row.
