Three-Dimensional Digital Tomosynthesis

Yulia Levakhina gives an introduction to the major challenges of image reconstruction in Digital Tomosynthesis (DT), particularly to the connection of the reconstruction problem with the incompleteness of the DT dataset. The author discusses the factors which cause the formation of limited angle artifacts and proposes how to account for them in order to improve image quality and axial resolution of modern DT. The addressed methods include a weighted non-linear backprojection scheme for algebraic reconstruction and a novel dual-axis acquisition geometry. All discussed algorithms and methods are supplemented by detailed illustrations, hints for practical implementation, pseudo-code, simulation results and real patient case examples. ContentsForward and Backprojection ModelIterative Image Reconstruction for TomosynthesisBackprojected Space in Image ReconstructionDual-Axis Tilt Acquisition Geometry Target GroupsAcademics and practitioners in the fields of computer science, X-ray imaging, computed tomography, tomosynthesis, iterative image reconstruction and medical imaging, radiologists and physicians. The AuthorYulia Levakhina earned her doctoral degree at the Institute of Medical Engineering, University of Lübeck, under the supervision of Prof. Thorsten M.
