INSIDEnet: Interpretable NonexpanSIve Data‐Efficient network for denoising in grating interferometry breast CT

Medical Physics, Volume 49, Issue 6, Page 3729-3748, June 2022., 2022
Abstract Purpose Breast cancer is the most common malignancy in women. Unfortunately, current breast imaging techniques all suffer from certain limitations: they are either not fully three dimensional, have an insufficient resolution or low soft‐tissue contrast.

[Retracted] Study on the Cytotoxic Microstructure of Titanium Dioxide Nanoparticles by X‐Ray Phase‐Contrast CT Imaging

Contrast Media &Molecular Imaging, Volume 2022, Issue 1, 2022., 2022
To address the problem of microstructural analysis of titania nanoparticles with high cytotoxicity, the authors propose X‐ray phase‐comparative CT imaging studies. In this method, the HE‐stained section samples were compared with the X‐ray phase‐contrast CT imaging microscopic images, and 3D texture analysis was used to observe the changes in the ...

Matter-wave interference of a native polypeptide

Nature Communications, 2020
Matter-wave interferometry of complex molecules is challenging due to difficulties in preparing and detecting molecular beams. Here the authors demonstrate quantum behavior of a polypeptide using matter-wave interference in an all-optical time-domain ...

Discrimination analysis of breast calcifications using x‐ray dark‐field radiography

Medical Physics, Volume 47, Issue 4, Page 1813-1826, April 2020., 2020
Background X‐ray dark‐field radiography could enhance mammography by providing more information on imaged tissue and microcalcifications. The dark field signal is a measure of small angle scattering and can thus provide additional information on the imaged materials.

Explicit Filtering Based Low‐Dose Differential Phase Reconstruction Algorithm with the Grating Interferometry

Computational and Mathematical Methods in Medicine, Volume 2015, Issue 1, 2015., 2015
X‐ray grating interferometry offers a novel framework for the study of weakly absorbing samples. Three kinds of information, that is, the attenuation, differential phase contrast (DPC), and dark‐field images, can be obtained after a single scanning, providing additional and complementary information to the conventional attenuation image.

Direct Fan‐Beam Reconstruction Algorithm via Filtered Backprojection for Differential Phase‐Contrast Computed Tomography

X-Ray Optics and Instrumentation, Volume 2008, Issue 1, 2008., 2008
Recently, a novel data acquisition method has been proposed and experimentally implemented for differential phase‐contrast computed tomography (DPC‐CT), in which a conventional X‐ray tube and a Talbot‐Lau‐type interferometer were utilized in data acquisition.
