- Test mosaic of stacks of copper and silver foils, total thicknesses between 12.5 µm and 600 µm, fitted in a plastic grid on an aluminium backing.
- No way to tell which tiles are copper and which are silver, or even that the plastic grid is plastic, in the conventional absorption contrast image.
- Thickness information is also lost - a thinner piece of silver gives the same grey scale as a thicker piece of copper.
- IBEX MAP technology restores energy-dependent information, allowing reconstruction of an image containing both materials and thickness information.
Click on the arrows in the image pane to see the effect of IBEX technology on the analysis of the X‑ray image.
The sample data were collected in a single exposure using a tungsten X‑ray tube running at 70 kV and a silicon flat‑panel detector fitted with an IBEX MAP.
