We present “dynamic tomography” algorithms that allow for the high-resolution, time- resolved imaging of dynamic (ie, continuously time evolving) complex systems at existing x …
One of the main problems in discrete tomography is the reconstruction of binary matrices from their projections in a small number of directions. In this paper we consider a new …

Discrete tomography (DT) deals with the reconstruction of a function from its projections, when the function has a known discrete range. The knowledge of the discrete range …

We present a new algorithm for reconstructing binary images from their projections along a small number of directions. Our algorithm performs a sequence of related reconstructions …

How to perfectly recover a binary signal from its discrete Fourier transform (DFT) coefficients is studied. The theoretic lower bound and a practical recovery strategy are derived and …

Discrete tomography deals with image reconstruction of an object with finitely many gray levels (such as two). Different approaches are used to model the raw detector reading. The …

We consider the problem of recognizing arbitrary finite subsets of Z2 by X-rays corresponding to a small set of directions S. We show that if we fix any rectangle A in Z2 then …
A method is presented for quantitative polychromatic cone-beam phase-contrast tomographic imaging of a single-material object from few projections. This algorithm exploits …
In X-ray computed tomography (CT) increased information requirements (eg increased resolution) typically lead to a concurrent increase in the required number of viewing angles …
