In the absence of external stimuli or overt behavior, the activity of the left and right cortical hemispheres shows fluctuations that are largely bilateral. Here, we show that these fluctuations are largely responsible for the variability observed in

Abstract Refraction-contrast computed tomography (RCT) using a refractive angle analyzer of Si perfect crystal can reconstruct the three-dimensional structure of biological soft tissue with contrast comparable to that of stained two-dimensional patho

In conventional phase-contrast imaging methods, an optimum distance that is essential for x-ray interference and wavefront separation must be maintained between the object and the x-ray detector. This distance determines the apparent focal size of th

Our previous study suggests that the cross-sectional morphology of ducts and branching of ducts in the nipple are associated with the presence of breast cancer. In this study, we evaluated whether cross-sectional morphology and duct branching of huma

PURPOSE The integration process used as a pre-processing step in the reconstruction of differential phase-contrast X-ray CT (d-PCCT) causes the measurement noise to propagate throughout the projection image, which is leading to increased ring artifac

We visualized the luminal structures generated by DCIS and UDH using a refraction-contrast X-ray CT technique, which provides a contrast close to stained tissue images, and showed that DCIS and UDH forms a bubble-like shape and a tube-like shape, res

Refraction-contrast X-ray computed tomography (RCT), which provides a high-contrast image of biological soft tissues, has recently been used in pathology and micro anatomy research. One of the characteristics of RCT is that the projection obtained by

The basic idea of X-ray dark-field imaging (XDFI), first presented in 2000, was based on the concepts used in an X-ray interferometer. In this article, we review 20 years of developments in our theoretical understanding, scientific instrumentation, a

X-ray dark-field imaging (XDFI) utilizing a thin silicon crystal under Laue case enables visualizing three-dimensional (3D) morphological alterations of human tissue. XDFI uses refraction-contrast derived from phase shift rather than absorption as th
