The purpose of this work is to demonstrate an ultra-fast reconstruction technique for digital tomosynthesis (dts) imaging based on the algorithm proposed by feldkamp. In this paper, c-arm tomosynthesis with digital detector was investigated as a novel three dimensional (3d) imaging technique digital tomosythses is an imaging. In digital tomosynthesis imaging as it deals with millions of input pixels in order to produce a reconstruction composed of billions of voxels. Digital tomosynthesis mammography: improvement of artifact reduction method for high-attenuation objects on reconstructed slices. Two-view digital breast tomosynthesis screening with synthetically reconstructed projection images: comparison with digital breast tomosynthesis with full-field. Introduction to digital breast tomosynthesis (dbt) dbt has been developed to deal with overlapping tissue in mammogram goal: improve dbt reconstruction.
