摘要： 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. At least the ROI portion of the 3D space between the emitter panel and the detector panel is represented by 3D volume elements (voxels), wherein at least some of those voxels represent respective portions of that space that are traversed by corresponding portions of a plurality of radiation rays each extending from a respective emitter to a respective detector and are associated with respective absorption coefficients representative of the radiation absorption characteristic of a corresponding portion of the ROI. The image reconstruction process is an iterative process in which neighboring voxels having similar calculated coefficients are combined into larger voxels, neighboring voxels having dissimilar calculated coefficients are divided into smaller voxels, and new absorption coefficients are calculated.

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.
