Adaptive algebraic reconstruction technique.
Algebraic reconstruction techniques (ART) are iterative procedures for reconstructing objects from their projections. It is proven that ART can be computationally efficient by carefully arranging the order in which the collected data are accessed during the reconstruction procedure and adaptively adjusting the relaxation parameters. In this paper, an adaptive algebraic reconstruction technique ...
متن کاملSpherically symmetric volume elements as basis functions for image reconstructions in computed laminography.
BACKGROUND Laminography is a tomographic technique that allows three-dimensional imaging of flat and elongated objects that stretch beyond the extent of a reconstruction volume. Laminography images can be reconstructed using iterative algorithms based on the Kaczmarz method. OBJECTIVE This study aims to develop and demonstrate a new reconstruction algorithm that may provide superior image rec...
متن کاملThe Algebraic Reconstruction Technique (art)∗
Projections of charged particle beam current density (profiles) are frequently used as a measure of beam position and size. In conventional practice only two projections, usually horizontal and vertical, are measured. This puts a severe limit on the detail of information that can be achieved. A third projection provides a significant improvement. The Algebraic Reconstruction Technique (ART) use...

متن کاملApplying a Priori Information to Computed Laminography
Reconstructed 3D volumes from computed laminography data suffer from blurring artefacts due to the laminographic geometry. Such losses in quality can be tackled by the use of a priori information about the test object which can be integrated into the iterative reconstruction process. However, this requires the position of the a priori model to be fitted exactly to the measured data. A (semi-)au...
