A method and apparatus for generating a tooth panoramic image, and a panoramic machine for photographing teeth. The method comprises: determining a frame frequency of a reference detector, and determining a frame frequency of a photographing detector according to the frame frequency of the reference detector; photographing the teeth of a user according to the frame frequency of the photographing detector so as to generate a plurality of images; performing shift superposition on the plurality of images so as to generate a first panoramic image; acquiring a fuzzy region in the first panoramic image; and performing frame frequency adjustment on each row in the fuzzy region so as to form a clear image, and fusing the clear image and the first panoramic image so as to generate a second panoramic image. Each row of an image is imaged by using different frame frequency change rules, so that both the cusps and the roots of the teeth of a user can be placed in a focusing layer, so as to form an image clearly, which improves the clarity of a panoramic image.

A mobile radiography system includes a moveable arm having an x-ray source attached thereto which can be manually positioned by an operator. A sensor detects a location of a bed or other object relative to the radiography system and generates location information so that a programmable system can restrict lateral movement of the system or arm within a zone proximate the bed or other object.

A specimen radiography system may include a controller and a cabinet. The cabinet may include an x-ray source, an x-ray detector, and a specimen drawer disposed between the x-ray source and the x-ray detector. The specimen drawer may be automatically positionable along a vertical axis between the x-ray source and the x-ray detector.

The present disclosure relates to the field of a cabinet x-ray incorporating an x-ray tube, an x-ray detector, and an optical camera for the production of organic and non-organic images. The computing device receives data including video data from an optical camera, a laser detector, an infrared detector, an ultrasonic detector, or a weight scale or pressure sensor, and determines automatically, based on the resultant data, if a sample/specimen has been left in the sample chamber. In particular, the disclosure relates to a system and method with corresponding apparatus for automatic detection if a sample/specimen has been left in the sample chamber without having to open the chamber door.

An imaging device for obtaining long-film images of an anatomical element of a patient or of another object includes a wheeled base comprising an elongate track; a trolley comprising a base portion slidably connected to the elongate track and an upper portion rotatably connected to the base portion, the trolley slidable along the elongate track a distance of at least 40 cm; a C-shaped arm defining a semi-circle about a C-shaped arm axis, the C-shaped arm rotatably supported by the upper portion of the trolley; a source fixedly secured to the C-shaped arm; and a detector fixedly secured to the C-shaped arm opposite the source.

A detector system for an x-ray imaging device includes a detector chassis, a plurality of sub-assemblies mounted to the detector chassis and within an interior housing of the chassis, the sub-assemblies defining a detector surface, where each sub-assembly includes a thermally-conductive support mounted to the detector chassis, a detector module having an array of x-ray sensitive detector elements mounted to a first surface of the support, an electronics board mounted to a second surface of the support opposite the first surface, at least one electrical connector that connects the detector module to the electronics board, where the electronics board provides power to the detector module and receives digital x-ray image data from the detector module via the at least one electrical connector.

According to one embodiment, an X-ray diagnosis apparatus includes an X-ray generator, an X-ray diaphragm, an X-ray detector, an image capturing unit, a blood vessel running information acquiring unit, a device position specifying unit, and a diaphragm controller. The X-ray generator emits X-rays. The X-ray diaphragm restricts a region to be irradiated with X-rays emitted from the X-ray generator. The X-ray detector detects X-rays emitted from the X-ray generator. The image capturing unit acquires an X-ray image based on a detection result obtained by the X-ray detector. The blood vessel running information acquiring unit acquires blood vessel running information. The device position specifying unit specifies the position of a device in the X-ray image. The diaphragm controller controls the X-ray diaphragm based on the blood vessel running information and the position of the device.

The X-ray imager combines a pulsed X-ray source with a time-sensitive X-ray detector to provide a measure of ballistic photons with a reduction of scattered photons. The imager can provide a comparable contrast-to-noise X-ray image using significantly less radiation exposure than conventional X-ray imagers, notably about half of the radiation.
