Spectroscopic detector under development

How it works?

CT takes advantage of the penetrating nature of X-rays to image the inside of a material based on the principle that each component of a material attenuates the X-ray beam differently depending on its electron density. The X-rays pass the sample and reach the detector. The they generate a 360 projection of the sample´s components which makes it possible to track each individual component in space, and thus allows to reconstruct the 3D volume of the sample. Note that the resolution is inversely proportional to the field of view. Samples < 2 cm diameter are necessary to achieve the highest resolution. Cylindrical samples are ideal but other geometries can be measured without any special treatment. The method is non-destructive.
