Researchers from the Paul Scherrer Institut have developed now an instrument that makes X-ray tomography possible at an unprecedented 3d resolution.
For thick samples, hard X-ray tomography was limited to a resolution of around 150 nanometres. For many years, X-ray tomography has been conducted at various synchrotron light sources, such as The swiss Light source at the PSI.

#Compact light source improves CT SCANS With its ability to image cross sections of the human body, X-ray computer tomography (CT) has become an important diagnostic tool in medicine.
Conventional CT SCANS are very detailed when it comes to bones and other dense body parts that strongly absorb X-rays.
However, the technique struggles with the visualization and distinction of"soft tissues"such as organs, which are more transparent to X-rays."

"More than One Kind of Contrastthe amount of detail in a CT SCAN depends on the difference in brightness,
but they become visible in phase-contrast tomography, "says the study's lead author, Elena Eggl, a researcher at the Technical University of Munich."
these methods require X-ray light with a well-defined wavelength aligned in a particular way--properties that conventional CT SCANNERS in hospitals do not deliver sufficiently.
