    Abstract: There is provided an x-ray imaging system (100) comprising an x-ray source (10), and an associated x-ray detector (20), wherein the x-ray detector (20) is a photon counting x-ray detector for enabling detection of photon-counting events. The x-ray imaging system (100) is configured for enabling acquisition of at least one phase contrast image based on detected photon-counting events. The x-ray detector (20) is based on a number of x-ray detector sub-modules, also referred to as wafers, each of which comprises detector elements, wherein the x-ray detector sub-modules are oriented in edge-on geometry with their edge directed towards the x-ray source, assuming the x- rays enter through the edge. Each x-ray detector sub-module or wafer has a thickness with two opposite sides of different potentials to enable charge drift towards the side, where the detector elements, also referred to as pixels, are arranged. The x-ray imaging system (100) is further configured to determine an estimate or measure of charge diffusion originating from a Compton interaction or an interaction through photoeffect related to an incident x-ray photon in an x-ray detector sub-module or wafer of the x-ray detector, and to determine an estimate of a point of interaction of the incident x-ray photon in the x-ray detector sub-module based on the determined estimate or measure of charge diffusion.

    Abstract: A method and an apparatus for almost scrap-less manufacturing of magnetic cores (100; 150; 200; 250) for electrical power transformers or reactors are provided. The method comprises the steps of cutting (S10) a cut-out (41) from the middle of a long side of a rectangular yoke plate made of electrical steel such that a symmetric gap is formed in the yoke plate, forming (S20) building elements (40; 40') of grain oriented electrical steel either from the cut-out (41) or from a rectangular limb plate, repositioning (S30) the building elements such that at least some of the building elements get a new orientation and/or position in relation to the yoke plate or the limb plate, and building (S50) a magnetic core (100; 150; 200; 250) by assembling at least yoke plates and repositioned building elements such that the repositioned building elements fit into the symmetric gaps formed in the yoke plates. Magnetic cores (100; 150; 200; 250) for electrical power transformers or reactors are also provided, where the core losses and noise levels are reduced compared to prior art technology. In particular, magnetic hybrid cores with grain oriented electrical steel and amorphous steel are provided.
