In this paper we study the reconstruction of moving object densities from undersampled
dynamic x-ray tomography in two dimensions. A particular motivation of this study is to use …

A crucial limitation of current high-resolution 3D photoacoustic tomography (PAT) devices
that employ sequential scanning is their long acquisition time. In previous work, we …

This article provides a mathematical analysis of singular (nonsmooth) artifacts added to
reconstructions by filtered backprojection (FBP) type algorithms for X-ray computed …

Compton scattering imaging is a nascent concept arising from the current development of
high-sensitive energy detectors and is devoted to exploit the scattering radiation to image …

Motion, eg, due to patient movement or improper device calibration, is inevitable in many
imaging modalities such as photoacoustic tomography (PAT) by a rotating system and can …

In this paper we propose a motion-aware variational approach to reconstruct moving objects
from sparse dynamic data. The motivation of this work stems from x-ray imaging of plants …

A main challenge in computerized tomography consists in imaging moving objects.
Temporal changes during the measuring process lead to inconsistent data sets, and …

We propose a novel approach to analyzing resolution of tomographic reconstruction. Instead
of following a conventional approach to obtain a global accuracy estimate, we investigate …

One major challenge in computerized tomography is to image objects which change during
the data acquisition and hence lead to inconsistent data sets. Motion artefacts in the …

Efficient representations of multivariate functions are critical for the design of state-of-the-art
methods of data restoration and image reconstruction. In this work, we consider the …
