INSPECTION OF A MEDIEVAL WOOD SCULPTURE USING COMPUTER TOMOGRAPHY
computed tomography wood sculpture analysis 3D modelling
2016/11/11
Computer tomography (CT) is an excellent technique for obtaining accurate 3D information about the human body. It allows to visualize the organs, bones and blood vessels, furthermore it enables to dia...
OBSERVATIONS ON THE PERFORMANCE OF X-RAY COMPUTED TOMOGRAPHY FOR DIMENSIONAL METROLOGY
X-ray computed tomography (XCT) dimensional metrology holeplate orientation beam hardening
2016/11/11
X-ray computed tomography (XCT) is a rising technology within many industries and sectors with a demand for dimensional metrology, defect, void analysis and reverse engineering. There are many variabl...

Compressed sensing based cone-beam computed tomography reconstruction with a first-order method
Department of Radiation Oncology Stanford University Stanford California 94305
2015/8/7
This article considers the problem of reconstructing cone-beam computed tomography (CBCT) images from a set of undersampled and potentially noisy projection measurements. The authors cast the reconstr...
The most demanding application of wide area di erential corrections to GPS is vertical positioning of aircraft on precision approach. Here the Wide Area Augmentation System (WAAS) combines accuracy re...
A New Ionospheric Estimation Algorithm for SBAS Combining Kriging and Tomography
Ionospheric Estimation Algorithm SBAS Combining Kriging Tomography
2015/6/26
One can divide the existing ionospheric methods for SBAS in two categories: tomography and methods relying on the thin shell model. At first sight, tomography appears to be the right choice. Tomograph...
COMPLEMENTARITY OF SAR POLARIMETRY AND TOMOGRAPHY FOR BUILDING DETECTION AND CHARACTERIZATION
SAR polarimetry tomography object detection segmentation
2014/4/24
In this paper we propose to study the potential of jointly using polarimetric and tomographic SAR data to recognize and localize buildings in complex scenarios. We present extraction methods for both ...
Anti-Spoof Reliable Biometry of Fingerprints Using En-Face Optical Coherence Tomography
Optical Coherence Tomography, En-Face OCT, Fingerprints, Biometry, High Resolution
2013/1/30
Optical coherence tomography (OCT) is a relatively new imaging technology which can produce high resolution images of three-dimensional structures. OCT has been mainly used for medical applications su...
Rockburst hazard determination by using computed tomography technology in deep Workface
Rockburst Elastic wave CT Velocity anomaly Inversion Verification
2012/3/28
The rockburst in mines results from the dynamic load coupled with static one in coal seams around workface zones, so it is essential to learn the stress distribution of the coal and surrounding rock f...
Full jet tomography of high-energy nuclear collisions
jet quenching reconstructed jet perturbative QCD
2011/10/11
Abstract: Parton energy loss in the hot QCD medium will manifest itself not only in leading hadron spectra but also in reconstructed jet productions in high-energy nucleus-nucleus collisions. In this ...
Network Tomography (or network monitoring) uses end-to-end measurements to characterize the network, such as estimating the network topology and localizing random or adversarial glitches. Under the se...
Direct Fan-Beam Reconstruction Algorithm via Filtered Backprojection for Differential Phase-Contrast Computed Tomography
Direct Fan-Beam Reconstruction Algorithm Filtered Backprojection Differential Phase-Contrast Computed Tomography
2009/9/4
Recently, a novel data acquisition method has been proposed and experimentally implemented for differential phase-contrast computed tomography (DPC-CT), in which a conventional X-ray tube and a Talbot...
层析成像合成孔径雷达(Tomography SAR)结合空间谱估计技术解决层叠效应时，首先要估计出高度维信号源数目，信号源数估计得正确与否直接关系到后续处理的估计性能。用传统的信息论方法估计时，由于数据受乘性噪声影响，估计性能下降。该文提出一种新的信号源数估计方法：双向平滑多视幅相估计(FB-MAPES)滤波器算法。通过Monte Carlo仿真对信息论方法中的GMDL算法和FB-MAPES方法的...
