In order to study potent microenvironments of malignant gliomas with a high- resolution x-ray imaging technique, an injection orthotopic glioma model was made using the Sprague-Dawley rat. Total brain tissue, taken out as an ex vivo model, was examin

Fluorescent X-ray computed tomography (FXCT) enables us to reveal the cross-sectional distribution of very low concentration of specific elements, e.g. I, Gd, or Au, in biomedical samples at a spatial resolution of several hundred micrometers, and it

Using X-ray fluorescent computed tomography (XFCT), the in vivo and ex vivo cerebral distribution of a stable-iodine-labeled cerebral perfusion agent, iodoamphetamine analog (127I-IMP), has been recorded in the brains of mice. In vivo cerebral perfus

A parallel x-ray beam that is made by an asymmetric-cut Bragg monochromator-collimator (MC) is incident on breast tissue so that the beam containing information from the breast tissue is incident upon a Laue-case angle analyzer (LAA). This beam is su

We derive a reconstruction algorithm for refraction-contrast computed tomography (CT) using dark-field imaging (DFI) optics, which can extract refraction information by a single shot, from the ray equation in geometrical optics. The proposed algorith

We first clarify the measurement process of fluorescent x-ray computed tomography using synchrotron sheet-beam. Then, we propose the analytical reconstruction method, and show its efficacy by computer simulation.

Phase‐contrast Computed Tomography (CT) delineates biological soft tissues, which cannot be clearly imaged using absorption‐contrast CT, at high contrast and high spatial resolution. Since the measurement system extracts phase‐shift information
