摘要: This invention relates to a high resolution and low dosage tomographic imaging in three dimensions, more particularly, fully analytical fast iterative statistical algorithm for image reconstruction from projections obtained spiral cone-beam x-ray scanner is described. The presented method allows improve the of reconstructed images and/or decrease intensity while maintaining quality CT images, because signals are adapted specific statistics this technique. location pixels detectors detector array new approach topology here avoids an inconsistency distribution coefficients assigned image, which appears formulation problem.
