Applications

Non-Destructive Testing

 
ADVACAM’s X-ray digital radiography imaging detectors are an ideal solution for many Non-Destructive Testing (NDT) applications. The photon counting detectors provide improved sensitivity, spatial resolution, contrast and signal-to-noise ratio. The broad range of detectable X-ray energy starting from 5 keV up to hundreds of keV or even MeV let the detectors capture from very light composite materials up to thick welded parts.
 
In addition, the energy discrimination helps suppress the scattered radiation and improving the contrast of measured images. NDT specialists and service providing companies can extend the portfolio of customers by those whose products could not be inspected by X-ray radiography in the past. Our new X-ray imaging technologies are useful for inspecting composite materials in the aerospace industry.
 
 

Mining and Geology

The energy sensitive photon counting detectors can help in this area thanks to the option of material identification in images. Drill cores from exploration bore holes can be now analysed in-situ identifying different minerals and providing immediate feedback for further exploration.  
 
Online monitoring of technological processes during mineral processing is another very important area where X-ray material resolved imaging plays an important role. It helps to increase effectivity of processing and reduce energy consumption leading not only to reduced costs, but also to lower environmental effects.
 
 

Spectral Imaging Of A Mouse

 
 
Cancer research, biomechanics, and drug testing are just a few examples of where X-ray imaging contributes to research in biology and medicine. New photon counting detectors represent a serious advancement for these applications, compared to previously used synchrotrons. The energy sensitivity of modern cameras opens better possibilities to identify individual types of tissue. That has important consequences in various industries, for example cancer research, where the tumour tissue can be better distinguished from the healthy one.
 
Spectral Radiography

The high sensitivity of photon counting detectors to low energy photons makes them useful for imaging low X-ray attenuating objects (i.e. light objects, such as tissue.) Thus, these detectors are ideal for bio-related applications. The low X-ray energy sensitivity (starting from ~3 keV) together with the high dynamic range reveals features in samples that remain hidden to other types of X-ray imaging detectors.
 
Spectral Computed Tomography

The spectral radiography can be extended to 3D by means of computed tomography. This makes it possible to recognize different types of tissue in real form. Again, this level of information can be incredibly helpful for cancer treatment research, as it gives better data for irradiation planning.
