May 2014 – Phys. Med. Biol. 59, 2801-11 (2014) - U. Lundström, U. K. Westermark, D. H. Larsson, A. Burvall, M. Arsenian Henriksson and H.M. Hertz

 

thumb-X-ray-phase-contrast-with-injected-gas-for-2  

A KTH/KI team demonstrates that the microvasculature of mouse tumors can be visualizedusing a MetalJet x-ray source from Excillum and a gas contrast agent. The time need to acquire a 2D-projection is a few seconds, and for a full 3D-tomography scan requires a few minutes. The MetalJet source used in this experiment operated with our Indium rich alloy (ExAlloy-I1).

thumb-Hertz-XRF-Opt-Lett-2014-1  

A KTH group demonstrates nanoparticle XRF-CT in mouse-size object, using a MetalJet x-ray source from Excillum, with very high spatial resolution and an acceptable dose. Montel optics was used to make sure that only the Indium K-alpha at 24 keV was used for the experiments.

thumb-comparison-of-two-x-ray-phase-contrast-imgaing-methods-with-a-microfocus-source  

A PSI/KTH team presents a comparison, for high-resolution imaging, between grating-based (GBI) and propagation-based x-ray (PBI) phase-contrast imaging, using a MetalJet x-ray source from Excillum. Using polychromatic radiation, in experiments and simulations, PBI shows a lower dose requirment, while GBI shows an advantage when it comes to quantitative refractive index reconstruction for multi-material samples.

thumb-Xray-grating-interferometry-with-a-liquid-metal-jet-source   A PSI/KTH team combines Excillum MetalJet sources with grating phase-contrast imaging and compares it with the use of a conventional microfocus source. They conclude that exposure times can be significantly reduced and visibility significantly improved with the metal-jet sources.

Thumb-collecting-data-in-the-home-laboratory---evolution-of-X-ray-sources-detectors-and-working-practices-1  

A comparison of different X-ray sources for X-ray crystallography written by Tadeusz Skarzynski at Agilent Technologies (now part of Rigaku Oxford Diffraction). Based on publically available information, he concludes that the beam flux density of the MetalJet source is expected to exceed the flux density from the most powerful microfocus rotating-anode generators available today.

thumb-first-application-of-liquid-metal-jet-sources-for-small-animal-imaging  

KTH/KI researchers demonstrate the first whole-body mouse tomography with high resolution employing Excillum MetalJet sources. In addition, it is shown that the high brightness of MetalJet sources allows for certain types of tumor demarcation without contrast agents in whole-body mouse.

thumb-x-ray-phase-contrast-co2-angiography-for-sub-10-um-vessel-imaging  

The KTH/KI team investigates the limits of the CO2/phase-contrast imaging method and concludes that sub-10-µm vessels can be imaged in thick tissue at acceptable dose, a factor 5-10 better than any competing method. The method is demonstrated in mouse ears and relies on the high brightness of Excillum MetalJet sources.

thumb-x-ray-phase-contrast-for-co2-microangiography  

A KTH/KI team demonstrates the use of carbon dioxide as an efficient contrast agent for phase-contrast imaging of microvasculature, providing high contrast with Excillum MetalJet sources. The method is demonstrated on rat kidney, showing 3D tomographic imaging down to 60 µm vessels at acceptebale dose.
