Researchers at Göttingen University have devised a new technique for X-ray color imaging. Researchers at the University of Göttingen have created a new approach to generate colored X-ray images. Previously, the only way to determine the chemical composition and arrangement of components in a sample
Artistic representation showing how an image is created using the newly developed method. Two colors – green and magenta – are emitted by fluorescing atoms in the sample due to X-Ray excitation. The grey round object represents an optic casting a shadow on the detector. The algorithm then produces an actual image with two colors – the intensity of which represents the density of the fluorescing atoms within the sample.
For their new method, the scientists used an X-ray color camera developed by PNSensor in Munich and a novel imaging system that essentially consists of a specially structured, gold-coated plate between the object and the detector, which means the sample casts a shadow. “We have developed an algorithm that allows us to quickly and robustly create a sharp image, simultaneously for each X-ray color,” explains first author Dr. Jakob Soltau, a postdoctoral researcher at the Institute for X-ray Physics at the University of Göttingen.
