imaging cellular architecture with x rays
Current Opinion in Structural Biology, 2010Co-Authors: Carolyn A Larabell, K A NugentAbstract:X-ray imaging of biological samples is progressing rapidly. In this paper we review the progress to date in high-resolution imaging of cellular architecture. In particular we survey the progress in soft X-ray tomography and argue that the field is coming of age and that important biological insights are starting to emerge. We then review the new ideas based on coherent diffraction. These methods are at a much earlier stage of development but, as they eliminate the need for X-ray optics, have the capacity to provide substantially better spatial resolution than zone plate-based methods.

quantitative phase imaging using hard x rays
Coherent Electron-Beam X-Ray Sources: Techniques and Applications, 1997Co-Authors: K A Nugent, Timur E Gureyev, D Cookson, David M Paganin, Z BarneaAbstract:The quantitative imaging of phase object using 16 keV X-Rays is reported. The theoretical basis of the techniques is presented along with its implementation using a synchrotron x-ray source. We find that our phase image is in quantitative agreement with independent measurements of the object.© (1997) COPYRIGHT SPIE--The International Society for Optical Engineering.

Occult capitate fracture through a bone island – SPECT/CT arthrography imaging
European Journal of Hybrid Imaging, 2018Co-Authors: Klaus Strobel, Lidija Antunovic, Wouter Van Der Bruggen, Gopinath Gnanasegaran, Willm Uwe Kampen, Tim Van Den Wyngaert, Edmond Rust, Torsten Kuwert, Frédéric PaychaAbstract:Background Single photon emission tomography/computed tomography ( SPECT/CT) combines the strengths of bone scintigraphy and CT and serve as an important alternative to magnetic resonance (MR) imaging in carpal trauma patients if conventional X-Rays are equivocal. Case presentation In a young patient with pain 4 days after carpal trauma conventional X-Rays were negative for fracture and MR showed only bone bruise. SPECT/CT arthrography one month later revealed intensive uptake in the capitate bone corresponding to a fracture through a bone island on the CT part of the study. Conclusion SPECT/CT combines the sensitivity of bone scintigraphy and specificity of (diagnostic) CT and might serve as an important second line imaging modality for the detection of occult carpal fracture.
