The development of a criterion for near-optimal selection of the Paganin-filter parameter based on noise power analysis measured via an image's noise power spectrum is described.

This study aims to guide users of dark-field imaging in selecting the most suitable technique for their imaging goals. To this end, we provide a summary table and highlight opportunities for future research into the sources of dark-field contrast across emerging methods.

Geometrical magnification and X-ray energy are optimized with respect to spatial resolution, contrast, noise, radiation dose and other image quality characteristics. The optimization is performed using a simple theoretical model of a homogeneous edge feature embedded in a bulk uniform sample, and the resulting generic analytical expressions for image quality characteristics are evaluated for several sets of parameters relevant to synchrotron-based in-line X-ray imaging setups.

A method for in situ imaging of human-sized animal lungs using the Imaging and Medical Beamline (IMBL) at the Australian Synchrotron is presented.

A biomedical X-ray imaging quality characteristic, suitable for quantitative assessment of X-ray images of biological samples, is introduced and then applied to analysis of propagation-based X-ray phase-contrast computed tomography images of mastectomy samples.

Application of 3D phase retrieval in a multi-step, masking framework allows for strong phase retrieval to be applied near highly attenuating materials without compromising spatial resolution. Demonstrations in brain computed tomography imaging show up to a 6.8-fold improvement in signal-to-noise ratio over standard phase retrieval processes, further broadening its dose-reduction potential in potential clinical applications.

Signal-to-noise ratio and spatial resolution are quantitatively analysed in the context of propagation based X-ray phase-contrast imaging. The performance of the method is shown to be determined by the Fresnel number and the ratio of the real decrement to the imaginary part of the refractive index of the imaged object.
