Background Cell behavior is the key to tissue regeneration. Given the fact that most of the
cells used in tissue engineering are anchorage-dependent, their behavior including …

Computed tomography (CT) entails the reconstruction of a function f from line integrals of f.
This mathematical problem is encountered in a growing number of diverse settings in …

This paper investigates high-resolution reconstructions from efficiently sampled data in
parallel-beam tomography, in particular, local tomography. A class of sampling schemes is …

In this paper, we study cone beam local tomography (LT). A new LT function g is proposed. It
is shown that g contains non-local artefacts, but their strength is an order of magnitude …

In this paper we study three-dimensional cone beam local tomography. We analyze the local
tomography function f_Λ^c, which was proposed earlier in AK Louis and P. Maass, IEEE …

Abstract The Body Centered Cubic (BCC) and Face Centered Cubic (FCC) lattices along
with a set of box splines for sampling and reconstruction of trivariate functions are proposed …

This paper studies ill-posed tomographic imaging problems where the image is sparsely
represented by a non-negative linear combination of Gaussians. Our main contribution is to …

This article contains a tutorial on the interaction between sampling theory and tomography
as well as some new results. We explore how sampling theorems are used in tomography to …

Local tomography for the Radon transform with nonsmooth attenuation is proposed and
justified. The main theoretical tool is analysis of singularities of pseudodifferential operators …

In this paper we develop local tomography (LT) for image reconstruction from motion
contaminated data. It is assumed that motion is known. We propose a new LT function f Λ …
