A method of capturing an x-ray image including providing an intraoral sensor having an array of pixels having a plurality of pixel clusters and a plurality of lines of pixels, each line of pixels having a first number of pixels different from the pixel clusters. The method may also include directing x-ray radiation toward the intraoral sensor and generating an electrical signal correlated to the x-ray radiation that impinges the pixel. The method may also include processing electrical signals generated by one or more pixels in the plurality of pixel clusters, generating at least one combined signal for at least one of the pixel clusters based on the signals from each of the pixels in the at least one of the pixel clusters, and initiating the capture of the image generated with information from each of the pixels in the array of pixels that is exposed to radiation.

Systems and methods are presented for evaluating a dental condition. A first digital representation of at least a portion of an oral cavity of a first patient is compared to a second digital representation of the oral cavity of the same patient. The first digital representation is representative of the oral cavity of the first patient at a first time and the second digital representation is representative of the oral cavity of the first patient at a second, later time. At least one clinically-significant difference between the first digital representation and the second digital representation are automatically identified and the first digital representation is displayed in a way that highlights the at least one clinically significant difference.

Systems and methods are presented for assisting in providing consistent alignment of a handheld intra-oral imaging device for a series of images. Live image data of the patient is received from the intra-oral image capture device and displayed on the display. A previously stored intra-oral image of the patient is accessed from the non-transitory memory and an alignment mask is generated based on the accessed previously stored intra-oral image. The alignment mask is displayed on the display overlaid onto the live image data. The system captures a new intra-oral image of the patient from the live image data and stores the new intra-oral image to the non-transitory memory.

A medical imaging device mountable on a support structure having a horizontal surface and at least one substantially vertical surface. The imaging device includes a frame and a gantry having a radiation source and a radiation detector. The gantry is rotatable with respect to the frame. The imaging device includes a first vertical adjustment element and a second vertical adjustment element. The first vertical adjustment element has a first end couplable to the horizontal surface and a second end coupled to the frame, the first end is located a first distance from the second end, and adjustable over a first range. The second vertical adjustment element has a third end coupled to the frame and a fourth end coupled to the gantry. The third end is located a second distance from the fourth end, and is adjustable over a second range, and the fourth end is rotatable with respect to the third end.

Methods, systems, and devices for determining characteristics of an intraoral dental imaging sensor. A method includes providing an intraoral dental imaging sensor having a housing and a magnetic field sensor disposed in or on the housing, placing the intraoral dental imaging sensor in a holder, positioning the intraoral dental imaging sensor and at least part of the holder in a mouth of a patient, attaching a reference magnet to the patient, receiving, by an electronic processor, magnetic field data from the magnetic field sensor, determining, by the electronic processor, information including a position of the intraoral dental imaging sensor in the mouth of the patient based at least in part on the magnetic field data, and detecting x-rays by the intraoral dental imaging sensor to produce image data.

Methods and systems for viewing images. One system includes a source of images, a computer, and a screen. The computer is configured to generate a graphical user interface or GUI. The GUI includes a first window in which one or more of the images are displayed. The GUI is displayed on the screen and the graphical user interface module generates an output or modifies the GUI in response to user input (e.g., tap, click, etc.). In response to the input, the graphical user interface generates an image-navigation map. The image-navigation map is displayed in a foreground of the first window and the one or more images are in displayed in a background of the first window. The image-navigation map includes one or more thumbnail images of at least one of the one or more images.


An intraoral x-ray sensor including a sensor housing and a universal serial bus (USB) data cable. The sensor housing has an opening. The USB data cable includes an outer sheath and a first data line, a second data line, a ground line, a power line, and at least two independent fillers positioned within the outer sheath. In one embodiment, at least two lines selected from the group consisting of the first data line, the second data line, the ground line, and the power line are twisted together to form a single bundle. The opening is configured to receive the data cable.

Methods and systems for storing and accessing dental images. The system includes an imaging system for acquiring x-ray projection frames. The imaging system is connected to a local server through a local area network. A cloud server communicates with devices on the local area. The x-ray projection frames are transmitted from the imaging system to the local server. The local server stores the series of related x-ray projection frames according to a specified policy. In one embodiment, the x-ray projection frames are compressed into a compressed image data set using a modified video compression prediction algorithm customized for x-ray images. The x-ray image data (whether compressed or not) is transmitted to the cloud server for storage. The x-ray image data can be accessed from the cloud server by external devices and by other local area networks.
