An x-ray imaging apparatus comprises a panel including individually energisable x-ray emitters, a detector and a processor, wherein the emitters and detector remain relatively stationary. The first set of x-ray emitters of the panel is energised to direct x-rays at the first object and surrounding area. The detector detects x-rays passing through the first object and surrounding area. Detected x-rays are processed to create a first x-ray image of the first object and surrounding area. A region of interest is selected from the first image which is smaller than the image of the first object and surrounding area. A second set of x-ray emitters of the panel is energised to direct x-rays at the region of interest. The detector detects x-rays passing through the region of interest. Detected x-rays are processed to create images of the region of interest to obtain tomosynthesis data showing structure of the region of interest.

Method of obtaining x-ray images

To obtain functional informationenergising a first set of x-ray emitters of the panel over a first period of time and directing the x-rays at the first object; using the detector to detect the x-raysafter passing through the first object; processing the detected x-rays to create a first set of images to obtain tomosynthesis data; energising a second set of x-ray emitters of the panel over a second period of time and directing the x-rays at the first object; using the detector to detect the x-rays after passing through the first object; processing the detected x-rays to create a second set of images to obtain tomosynthesis data, wherein the number of emitters used in the second period of time is less than used in the first period of time; and comparing at least some images from each set of images to provide functional information.

An x-ray imaging apparatuscomprising a support structure, the support structure supporting two separate x-ray emitting apparatus, a first x-ray emitting apparatuscomprising an x-ray emitter arranged for producing 2D tomosynthesis images, and a second x-ray emitting apparatuscomprising an array of distributed x-ray emitters arranged for producing 3D tomosynthesis images, the first and second x-ray emitting apparatus moveable relative to the support structure and arranged such that, in use, one of the first and second x-ray emitting apparatus is moveable into an operative position whereby x-rays are emitted therefrom towards a target, and simultaneously the other of the first and second x-ray emitting apparatus is movable into an inoperative position whereby x-rays are not emitted therefrom.

X-ray imaging apparatus

A portable x-ray imaging source () capable of motion-free x-ray tomosynthesis, wherein said source is suitable for dental and small body-part/small area imaging.

X-ray source

The disclosed system includes an emitter array for generating x-rays, a detector array for sensing a flux of x-rays transmitted through a region of interest; apparatus for holding, moving and aligning the emitter array relative to the region of interest and the detector array; electronic means for controlling the emitters and for reading and analyzing the output from the detectors and converting it to image data, and a display for displaying and manipulating the image data. The individual emitters are operated in multiple groups each illuminating a region of interest between the emitter array and the detector array such that the cone of radiation rays projected on the detector array from any single emitter in any one such group is substantially spatially separated from the corresponding projected cones from all other emitters in that same group.

Medical imaging system having an array of distributed X-ray generators

An x-ray collimator that may include a substrate containing a plurality of holes, each hole being frustoconical at one end and tubular at the other end for use in an x-ray imaging system, whereby the x-ray collimator may be aligned with a two-dimensional array of x-ray sources and a two-dimensional x-ray sensor, and whereby x-ray photons from the x-ray sources may pass through the collimator holes and emerge as a beam of x-ray photons in a narrow angle cone which may pass through a subject being imaged, positioned between the output holes of the collimator and the x-ray sensor.

X-ray collimator

An x-ray generator may include a plurality of electron field emitters; a target material; a plurality of energizable solenoid coils; and an electronic power and timing circuit. The generator may provide electrical current to at least one individual solenoid coil to create a magnetic field to cause the path of electrons emitted from the emitter closest to the energized solenoid coil to be defocused and/or deflected before the electrons reach the target material. The target material may comprise a low atomic number material and a high atomic number material, the high atomic number material being arranged in a regular pattern, such that, in use, the electrons may be aimed at either the high or the low atomic number material.
