| Abstract Scope |
The next dimension of X-ray imaging is here! Five dimensional Colour X-ray Imaging enables non-destructive 3D and 4D images to be complemented by a fifth chemistry dimension. Whilst the fundamental technology has been demonstrated it is, at present, inaccessible to most researchers due to the difficulty of acquisition and the processing of the vast multidimensional datasets it generates. We have recently built a new lab-based Colour X-ray CT scanner utilising a large detector array and a commercial cabinet-based system and are embarking on refining many of the data processing workflows. A 640 x 160 pixel hyperspectral HEXITEC detector with CdTe crystal has been integrated into a Nikon XTH 225 scanner. We have already demonstrated the capability of the detector for large-field-of-view bright-field imaging using absorption edge detection and are now moving to superresolution imaging using detector shifting. Initial applications include minerals, stained biomaterial, electronic waste and rare earth magnets. |
