#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."
"The CLS allows us to do multimodal tomography scans--a more advanced approach to X-ray imaging."
"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.
