Applying evidence-based medicine principles to hip fracture management.

Frontiers in surgery

Bernstein J, Morshed S, Helfet DL, Bhandari M, Ahn J.
PMID: 25593964
Front Surg. 2014 Oct 20;1:40. doi: 10.3389/fsurg.2014.00040. eCollection 2014.

Bone has the capacity to regenerate and not scar after injury - sometimes leaving behind no evidence at all of a prior fracture. As surgeons capable of facilitating such healing, it becomes our responsibility to help choose a treatment...

Direct Fourier Inversion Reconstruction Algorithm for Computed Laminography.

IEEE transactions on image processing : a publication of the IEEE Signal Processing Society

Voropaev A, Myagotin A, Helfen L, Baumbach T.
PMID: 27046874
IEEE Trans Image Process. 2016 May;25(5):2368-78. doi: 10.1109/TIP.2016.2546547.

Synchrotron radiation computed laminography (CL) was developed to complement the conventional computed tomography as a non-destructive 3D imaging method for the inspection of flat thin objects. Recent progress in hardware at synchrotron sources allows one to record internal evolution...

Analysis of spatial cross-correlations in multi-constituent volume data.

Journal of microscopy

Rack A, Helfen L, Baumbach T, Kirste S, Banhart J, Schladitz K, Ohser J.
PMID: 19017228
J Microsc. 2008 Nov;232(2):282-92. doi: 10.1111/j.1365-2818.2008.02100.x.

We investigate spatial cross-correlations between two constituents, both belonging to the same microstructure. These investigations are based on two approaches: one via the measurement of the cross-correlation function and the other uses the spatial distances between the constituents. The...

Appl Opt. 2013 Nov 20;52(33):8122-7. doi: 10.1364/AO.52.008122.

Pushing synchrotron x-ray radiography to increasingly higher image-acquisition rates (currently up to 100,000 fps) while maintaining spatial resolutions in the micrometer range implies drastically reduced fields of view. As a consequence, either imaging a small subregion of the sample...
