Quantitative characterization of amyloid deposits in murine models of alzheimer disease by phase-contrast x-ray imaging

Autor: Politano, A., Massimi, L., Pieroni1, N., Palermo, F., Sanna, A., Fratini, M., Bukreeva, I., Balducci, C., Cedola, A.

Alzheimer's is a neurodegenerative disease that is the most common form of dementia, but there is still no definitive cure for this disease. The noninvasive X-ray Phase Contrast Tomography (XPCT) imaging technique was used to study brain tissues in m

A cadaveric breast cancer tissue phantom for phase‐contrast X‐ray imaging applications

Autor: Cody C. Rounds, Chengyue Li, Wei Zhou, Kenneth M. Tichauer, Jovan G. Brankov

Publikováno v: Animal Models and Experimental Medicine, Vol 6, Iss 5, Pp 427-432 (2023)

Abstract Background As mammography X‐ray imaging technologies advance and provide elevated contrast in soft tissues, a need has developed for reliable imaging phantoms for use in system design and component calibration. In advanced imaging modaliti

Crystal-Based X-ray Interferometry and Its Application to Phase-Contrast X-ray Imaging, Zeff Imaging, and X-ray Thermography

Autor: Akio Yoneyama, Daiko Takamatsu, Thet-Thet Lwin, Shigehito Yamada, Tetsuya Takakuwa, Kazuyuki Hyodo, Keiichi Hirano, Satoshi Takeya

Publikováno v: Applied Sciences, Vol 13, Iss 9, p 5424 (2023)

Crystal-based X-ray interferometry (CXI) detects X-ray phase shifts by using the superposition of waves, and its sensitivity is the highest among the other X-ray phase-detecting methods. Therefore, phase-contrast X-ray imaging (PCXI) using CXI has th

Report

A theoretical framework for comparing noise characteristics of spectral, differential phase-contrast and spectral differential phase-contrast X-ray imaging

Autor: Mechlem, Korbinian, Sellerer, Thorsten, Viermetz, Manuel, Herzen, Julia, Pfeiffer, Franz

Spectral and grating-based differential phase-contrast X-ray imaging are two emerging technologies that offer additional information compared with conventional attenuation-based X-ray imaging. In the case of spectral imaging, energy-resolved measurem

Material Decomposition using Spectral Propagation-based Phase Contrast X-ray Imaging

Autor: Schaff, Florian, Morgan, Kaye S., Pollock, James A., Croton, Linda C. P., Hooper, Stuart B., Kitchen, Marcus J.

Material decomposition in X-ray imaging uses the energy-dependence of attenuation to virtually decompose an object into specific constituent materials. X-ray phase contrast imaging is a developing technique that can enhance image contrast seen from w
