X-ray photon-counting detectors (PCDs) become increasingly popular with applications in medical imaging, material science, and other areas. In this paper, we propose a non-uniformity data correction method for photon-counting detectors based on the f

This paper gives an update of the RTTOV (Radiative Transfer for TOVS) fast radiative transfer model, which is widely used in the satellite retrieval and data assimilation communities. RTTOV is a fast radiative transfer model for simulating top-of-atm

This paper outlines image domain material decomposition algorithms that have been routinely used in MARS spectral CT systems. These algorithms (known collectively as MARS-MD) are based on a pragmatic heuristic for solving the under-determined problem

Publikováno v: Radiation Detectors: Systems and Applications XVII.

We assessed the performance of a cadmium zinc telluride (CZT)-based Medipix3RX x-ray detector as a candidate for micro-computed tomography (micro-CT) imaging. This technology was developed at CERN for the Large Hadron Collider. It features an array o

Modelling circumstellar discs with three-dimensional radiation hydrodynamics

Autor: Tim J. Harries, David M. Acreman, David A. Rundle

Publikováno v: Monthly Notices of the Royal Astronomical Society. 403:1143-1155

We present results from combining a grid-based radiative transfer code with a Smoothed Particle Hydrodynamics code to produce a flexible system for modelling radiation hydrodynamics. We use a benchmark model of a circumstellar disc to determine a rob
