High resolution image reconstruction with constrained, total-variation minimization
Emil Y. Sidky, Rick Chartrand, Yuval Duchin +2
This work is concerned with applying iterative image reconstruction, based on constrained total-variation minimization, to low-intensity X-ray CT systems that have a high sampling…
A constrained, total-variation minimization algorithm for low-intensity X-ray CT
Emil Y. Sidky, Yuval Duchin, Christer Ullberg +1
Purpose: We develop an iterative image-reconstruction algorithm for application to low-intensity computed tomography (CT) projection data, which is based on constrained, total-vari…
A Novel UV Photon Detector with Resistive Electrodes
J. M. Bidault, P. Fonte, T. Francke +3
In this study we present first results from a new detector of UV photons: a thick gaseous electron multiplier (GEM) with resistive electrodes, combined with CsI or CsTe/CsI photoca…
Novel Single Photon Detectors for UV Imaging
P. Fonte, T. Francke, N. Pavlopoulos +2
There are several applications which require high position resolution UV imaging. For these applications we have developed and successfully tested a new version of a 2D UV single p…
A High Position Resolution X-ray Detector: an Edge on Illuminated Capillary Plate Combined with a Gas Amplification Structure
C. Iacobaeus, T. Francke, B. Lund-Jensen +4
We have developed and successfully tested a prototype of a new type of high position resolution hybrid X-ray detector. It contains a thin wall lead glass capillary plate converter…
Micropattern Gaseous Detectors
T. Francke, V. Peskov
Currently a revolution is taking place in the development of gaseous detectors of photons and particles. Parallel plate-type and wire-type detectors which dominated for years in hi…
