Bioluminescent imaging (BLI) is one of the most powerful and widely used preclinical imaging modalities. However, the current technology relies on the use of transgenic luciferase-expressing cells and animals and therefore can only be applied to a limited

A standard MRI system phantom has been designed and fabricated to assess scanner performance, scanner stability, scanner inter-comparability and accuracy of quantitative relaxation time imaging. The phantom is unique in having SI-traceability, a high level

Pushing the Limits of Bottom-Up Gold Filling for X-Ray Grating Interferometry

Daniel Josell, Thomas P. Moffat, Z Shi, K Jefimovs, L Romano, J. Vila-Comamala
The application of superconformal Bi-catalyzed Au electrodeposition for void-free filling of recessed trenches in X-ray gratings used in phase contrast imaging is detailed. Filling of trenches with aspect ratio (height divided by its width) up to 55 is

Characterization of 3-Dimensional Printing and Casting Materials for use in Computed Tomography and X-ray Imaging Phantoms

Bryan E. Yunker, Andrew Holmgren, Karl Stupic, J. L. Wagner, S Huddle, R Shandas, R. F. Weir, Katy Keenan, Edward Garboczi, Stephen E. Russek
Imaging phantoms are used to calibrate and validate the performance of medical computed tomography (CT) systems. Many new materials developed for three-dimensional (3D) printing processes may be useful in the direct printing or casting of biomimetic and
