“…By using the coherence properties, chemical element-specific imaging becomes possible. Furthermore, the absorption microtomography can be turned to phase-contrast microtomography, which images the distribution of refractive indices and therefore will allow soft tissue differentiation [50]. Considering that physical background, the data revealed by the imaging process are not limited to geometry information, but contribute to the material parameter set as well (e.g., density distribution) and directly represent specific material inhomogeneities.…”

Obtaining high-resolution three-dimensional (3D) geometry data performs a necessary assumption for modeling cochlear mechanics. Preferably this procedure has to be done noninvasively to preserve the original morphology. Depending on the actual application, various levels of spatial resolution and tissue differentiation should be reached. Here a new approach is presented which allows 3D imaging of temporal bone specimens with intact regions of interest and spatial resolution currently in the 10-μm range, but providing capabilities for future enhancements down to the submicron level. The technique is based on microtomography by X-rays or synchrotron radiation respectively. The structural data are reconstructed and converted to geometry data by 3D image processing, and eventually transferred into simulation environments, e.g., Finite Element Analysis, but may also be used for general visualization tasks in research, clinics, and education.

Summary We demonstrate simultaneous phase and amplitude extraction from a single defocused image of a homogeneous object. Subject to the assumptions explicitly stated in the derivation, the algorithm solves the twin‐image problem of in‐line holography and is capable of analysing data obtained using X‐ray microscopy, electron microscopy, neutron microscopy or visible‐light microscopy, especially as they relate to defocus and point projection methods. Our simple, robust, non‐iterative and computationally efficient method is applied to data obtained using an X‐ray phase contrast ultramicroscope.
