A hybrid x-ray device for mounted and portable use. The hybrid x-ray device can include a housing, an x-ray source, a support connector, a shield connector, and an interlock. The x-ray source is coupled to the housing and configured to generate x-ray radiation. The support connector is coupled to the housing and configured to mechanically couple to a support arm. The shield connector is coupled to the housing and configured to mechanically couple to a removable radiation shield. The interlock is coupled to the x-ray source and configured to disable activation of the x-ray source when both: (a) the support connector is mechanically uncoupled from the support arm, and (b) the shield connector is mechanically uncoupled from the removable radiation shield.

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 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 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.
