摘要: Image quality for flat-panel array tomosynthesis acquisition is not equivalent to CT because of the reduced number of image angles that are acquired in DT, and also image quality is not uniform throughout the volume and decreases near to the fixed detector array and the fixed flat-panel source. The present invention provides a system for obtaining an X-ray image of a subject 1 in which an emitter panel 3 and detector 7 are movable on a smart armature 9. In this way, image quality can be improved, for example by combining acquisitions taken from different orientations, thereby approaching the quality of conventional CT imaging, whilst still maintaining the lower cost and dose of conventional DT imaging.

摘要: 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.

摘要: 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.

摘要: The present invention seeks to reduce the burden of producing high-resolution tomograms by using an initial scan on a predetermined grid 10 to obtain a minimal set of images, and then regions of interest 20 are identified for further scanning. The further scanning locations 40 are determined by image entropy or gradient found in the previous iteration; such regions are indicative of edges, cracks or complex structure within the region. After each iteration, the level of information (e.g. image entropy or gradient) will decrease relative to the pixel/voxel size. In this way, a more efficient way to scan is achieved.

摘要: 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.

摘要: An x-ray imaging system and method for reconstructing three-dimensional images of a region of interest from spatially and temporally overlapping x-rays using novel reconstruction techniques are provided. The x-ray imaging system may include a detector to generate a signal in response to x-rays incident upon the detector, wherein the signal indicates the intensity of the x-rays incident upon a pixel of the detector, a plurality of x-ray sources arranged to emit x-rays such that said x-rays pass through a region of interest (ROI) and spatially and temporally overlap at the pixel of the detector, and a processing unit to receive the signal indicating the intensity of x-rays incident upon the pixel of the detector and generate an estimate of the intensity attributable to each of the two or more x-rays overlapping at the pixel of the detector.

摘要: An x-ray generator may include a plurality of electron field emitters; a target material; a plurality of energisable 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 energised 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.
