Abstract: An x-ray imaging system includes an x-ray source and detector. The detector is a photon counting x-ray detector, enabling detection of photon-counting events. The system acquires at least one phase contrast image based on photon-counting events. The detector includes x-ray detector sub-modules, also referred to as wafers, each including detector elements. The 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 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/pixels, are arranged. The system estimates charge diffusion from a Compton interaction or an interaction through photoeffect related to an incident x-ray photon in a sub-module or wafer of the x-ray detector, and estimates a point of interaction of the x-ray photon sub-module based on the determined estimate of charge diffusion.

Abstract: An x-ray imaging apparatus includes an x-ray source and detector with multiple detector elements. The source and detector are on a support that rotates around a subject, enabling projections at different view angles. The apparatus operates the x-ray source in switched kVp mode for alternately applying different voltages, including lower and higher voltages, during rotation to enable lower-energy and higher-energy exposures over the projections, providing for lower-energy projections and higher-energy projections. The x-ray detector is a photon-counting multi-bin detector allocating photon counts to multiple energy bins, and the apparatus selects counts from at least a subset of the bins to provide corresponding photon count information for both lower- and higher-energy projections.

Abstract: The disclosed method enables estimating an initial point of interaction of an x-ray photon in a photon-counting x-ray detector, based on a number of x-ray detector sub-modules or wafers, each including detector elements. The x-ray detector sub-modules are oriented in edge-on geometry with the edge directed towards the x-ray source, assuming the x-rays enter through the edge.

Basically, the method includes: determining an estimate of charge diffusion originating from a Compton interaction or an interaction through photoeffect related to the x-ray photon in a detector sub-module or wafer of the x-ray detector; and estimating the initial point of interaction along the thickness of the detector sub-module based on the determined estimate of charge diffusion.
