Practical adaptive quantum tomography
We introduce a fast and accurate heuristic for adaptive tomography that addressesmany of the limitations of priormethods. Previous approaches were either too computationally intensive or tailored to handle special cases such as single qubits or pure states. By contrast, our approach combines the efficiency of online optimizationwith generally applicable andwell-motivated data-processing techniq...
متن کاملPractical cone-beam lambda tomography.
As a potentially important technology for medical x-ray computed tomography (CT), lambda tomography (LT) is to reconstruct a gradient-like image only from local projection data. Based on our recently derived exact fan-beam LT formula, [H. Y. Gu and G. Wang, Int. J. Biomed. Imaging 2006(1), 1-9 (2006)] here we propose a practical cone-beam LT algorithm for LT reconstruction from local data colle...
متن کاملA practical method to determine the effective resolution in incoherent experimental electron tomography.
It is not straightforward to determine resolution for a 3D reconstruction when performing an electron tomography experiment. Different contributions such as missing wedge and misalignment add up and often influence the final resolution in an anisotropic manner. The conventional resolution measures can not be used for all of the reconstruction techniques, especially for iterative techniques whic...
متن کاملDouble-tilt electron tomography.
Fidelity of tomographic reconstructions is improved and reconstruction artifacts are reduced, without increasing the number of projections, by combining tilt series taken around two orthogonal axes. Test reconstructions were made from high-voltage EM of rat liver mitochondria in a 0.6 micron thick plastic section. A number of schemes for selecting tilt angles for the projections are compared. A...
متن کاملPhysical and Practical Challenges in Analytical Electron Tomography of Aluminum Alloys
For a thorough understanding of a material, investigations at the nanoscale are often essential. Analytical techniques like electron energy loss spectroscopy (EELS) and energy dispersive X-ray spectroscopy (EDXS) in probe corrected scanning transmission electron microscopy (STEM) can reveal important chemical information necessary for the development and improvement of high-tech materials. The ...
