X-ray phase-contrast microscopy and microtomography

Optics Express, 2003
In-line phase contrast enables weakly absorbing specimens to be imaged successfully with x-rays, and greatly enhances the visibility of fine scale structure in more strongly absorbing specimens. This type of phase contrast requires a spatially coherent beam, a condition that can be met by a microfocus x-ray source. We have developed an x-ray microscope,

Polydopamine Coating in Trabecular Bone‐Like Scaffolds With Strontium‐Substituted Nanohydroxyapatite for Bone Tissue Engineering

Journal of Applied Polymer Science, Volume 143, Issue 9, March 5, 2026.
PLA and strontium‐substituted hydroxyapatite filaments were used in 3D printing to fabricate a trabecular‐inspired scaffold. The scaffold was functionalized with a polydopamine coating. Characterization revealed enhanced surface properties and mechanical performance, supporting its potential application in bone tissue engineering.

An anatomical study of the subarachnoid space surrounding the trigeminal ganglion in horses—in preparation for a controlled glycerol rhizotomy in equids

Frontiers in Veterinary Science
IntroductionEquine trigeminal-mediated headshaking is a painful neuropathic disorder comparable to trigeminal neuralgia in humans. The selective destruction of pain fibers within the trigeminal ganglion, called rhizotomy, is the surgical treatment of ...

A microCT Study of Three-Dimensional Patterns of Biomineralization in Pig Molars

Frontiers in Physiology, 2018
Domestic pig molars provide an interesting system to study the biomineralization process. The large size, thick enamel and complex crown morphology make pig molars relatively similar to human molars.

Evaluating the Microstructure and Interaction of Bioaggregates in Concrete Using microCT

X-Ray Spectrometry, Volume 55, Issue 2, Page 285-293, March/April 2026.
ABSTRACT This study investigates the use of x‐ray computed microtomography (microCT) to evaluate the incorporation of bioaggregates—specifically macauba (Acrocomia aculeata) endocarp and jute fibers—into cement‐based composites. MicroCT enables non‐destructive, three‐dimensional characterization of the internal microstructure, providing insights into ...

Pathological Studies in Uteruses by X-ray Microtomography

Brazilian Journal of Radiation Sciences
X-ray computed microtomography (microCT) is an advanced technique for evaluating materials that uses the principle of X-ray attenuation to form high-resolution two- and three-dimensional images.

Neutron microtomography of voids in gold

MethodsX, 2017
Pilot attempt of the neutron microtomography of voids in gold carried out using the Neutron Microscope instrument is presented in the paper. The paper demonstrates that neutron microtomography provides viable alternative to X-ray imaging for the assessment of porosity in high atomic number materials.

Copaiba Oil–Resin Reduces the Alveolar Bone Damage Triggered by Apical Periodontitis in Rats

International Endodontic Journal, Volume 59, Issue 3, Page 511-523, March 2026.
ABSTRACT Aim This study aimed to investigate the effects of copaiba oil–resin on induced apical periodontitis in rats. Methodology A total of 24 male Wistar rats were divided equally into three groups (eight animals each): control (C), apical periodontitis (AP) and apical periodontitis with copaiba administration (AP + COP).

Injecting nerves with radiological contrast as a novel method of studying the peripheral nervous system

Journal of Anatomy, Volume 248, Issue 3, Page 490-500, March 2026.
We present a method of injecting peripheral nerves with radiopaque contrast and subsequent CT scanning that produces excellent 3D models of the nerves, leaving the specimens intact and ready for further analysis (e.g., for micro‐CT or histology). Abstract The peripheral nervous system has been the subject of various studies on topics ranging from the ...

Synchrotron phase-contrast microtomography of coprolites generates novel palaeobiological data

Scientific Reports, 2017
Coprolites (fossil faeces) reveal clues to ancient trophic relations, and contain inclusions representing organisms that are rarely preserved elsewhere.
