Journal ArticleDOI
Phase retrieval in X-ray phase-contrast imaging suitable for tomography
TL;DR: This work outlines derivations, approximations and assumptions, and shows which methods are similar or identical and how they relate to each other, and performs numerical phase-retrieval for all methods.
Journal ArticleDOI
Speckle-based x-ray phase-contrast and dark-field imaging with a laboratory source.
Irene Zanette,Tunhe Zhou,Anna Burvall,Ulf Lundström,Daniel H. Larsson,Marie-Christine Zdora,Pierre Thibault,Franz Pfeiffer,Hans M. Hertz +8 more
TL;DR: Algorithms for phase and dark-field imaging using speckle tracking are introduced, and it is shown that they yield superior results with respect to existing methods.
Journal ArticleDOI
A 24 keV liquid-metal-jet x-ray source for biomedical applications
TL;DR: The high photon energy compared to existing liquid-metal-jet sources increases the penetration depth and allows imaging of thicker samples and the applicability of the source in the biomedical field is demonstrated by high-resolution imaging of a mammography phantom and a phase-contrast angiography phantom.
Journal ArticleDOI
X-ray phase contrast for CO2 microangiography
Ulf Lundström,Daniel H. Larsson,Anna Burvall,Per Takman,Lena Scott,Hjalmar Brismar,Hans M. Hertz +6 more
TL;DR: A laboratory method for imaging small blood vessels using x-ray propagation-based phase-contrast imaging and carbon dioxide (CO(2)) gas as a contrast agent and the limited radiation dose in combination with CO(2) being clinically acceptable makes the method promising for small-diameter vascular visualization.
Journal ArticleDOI
X-ray phase-contrast tomography for high-spatial-resolution zebrafish muscle imaging.
TL;DR: It is shown that the three-dimensional muscular structure of unstained whole zebrafish can be imaged with sub-5 μm detail with X-ray phase-contrast tomography, and the method opens up for whole-body imaging withSub-cellular detail also of other types of soft tissue and in different animal models.
