Technical Information
X-ray imaging allows the determination and visualisation of the internal structure of a wide range of components and materials. Using a microfocus source of radiation, projection geometry and an imaging detector such systems have found application in many areas of science and industry.

-
Phase and Absorption Imaging
X-rays undergo absorption, refraction and diffraction as they interact with the sample. -
Capturing Phase Data
The projection geometry of XRT’s X-ray phase contrast imaging systems allows this refraction and diffraction effect to be maximised and captured. -
Enhanced Imaging Outcomes
X-ray phase contrast data results in a sharpened and improved image through increased delineation of the boundaries and edges of features. -
XRT's Patent Portfolio
XRT owns a substantial portfolio of intellectual property in phase contrast imaging protected by international patents.

X-rays, Discovery and History Part 1. "A new kind of ray"
On November 8 1895, Wilhelm Conrad Röntgen, then Professor of Physics at the University of Würzburg in Germany discovered what he called ‘a new kind of ray’ with remarkable penetrating properties.
-
X-rays, Discovery and History Part 2. "New branches of science"
The hundred or so years since the discovery of X-rays in 1895 has seen the emergence of a diverse range of imaging and analytical X-ray technologies, exploiting every known property of these new rays.
-
X-rays, Discovery and History Part 3. "Imaging"
The non-destructive nature of X-ray imaging has permitted a wide range of applications in testing and diagnosis for science, medicine and industry. Additionally, differing X-ray wavelengths may be utilized to selectively increase visibility of features of i nterest.

The Help Files - "Contrast transfer function"
Imaging parameters will determine both absorption (amplitude) and phase contrast according to the Contrast Transfer function.
-
The Help Files - "Tomographic imaging"
A tomographic image or tomogram is a three dimensional array of values representing a continuous distribution of some sample property (such as density).
