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.

Medical imaging system with a fixed array of x-ray detectors and a fixed array of x-ray emitters for producing a digital 3-dimensional image

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.
