In order to provide improved image quality, in particular for noise reduction in X-ray images, the method comprises the steps of acquiring (112) at least a first (118) and a second image (120) of the same region with different focal spot sizes of the X-ray tube, wherein one of the first and the second images is acquired with a small focal spot and the other image is acquired with a large focal spot. Then the two images are combined (114), wherein the combination step includes decomposing (122) the image data of the first image and the second image, determining the noise content in the decomposed data, determining (130) at least one weighting factor (132), depending on the signal content and noise content of the decomposed data of at least one of the two images, modulating (136) the decomposed image data of at least one of the two images using the weighting factor and recomposing (142) the decomposed image data of the at least two images to form a single new image (116).

Abstract: The present disclosure relates to combustion systems and components for rotary ramjet engines. An injection system, optionally stratified for ease of engine startup, provides an air and fuel mixture to a combustion chamber. An ignition system ignites the mixture. A flameholding system may be positioned for communication with the combustion chamber to force an ignited flow of the air and fuel mixture toward a center of rotation within the ramjet engine. The ramjet engine may comprise a diverging stator for improved exhaust efficiency. Ignition may take place in the engine air intake. Alternatively, ignition may take place within the combustion chamber using a dual-hub electrically charged system. An impulse turbine may use recirculation of injected fuel to cool a rim-rotor and/or to reduce windage on the rim-rotor. A sealing system may reduce gas leaks from a fuel conduit into the engine air intake.

Abstract: A modified Laplacian-pyramid method and system filters (340-360, 440-460) the Gaussian image at each level (31-33, 41-43) of the pyramid, and uses the filtered Gaussian image (341-361, 441-461) to produce the Laplacian-pyramid images (349-369,449-469). The filtering of the Gaussian image is adaptive, and based at least in part on the characteristics of the Gaussian image at each stage. In one example embodiment, two filters (Fl, F2) are used at each stage, and the Laplacian image (349-369) is based on a filtered version of the Gaussian image and an upsampled filtered version of a downsampling (346-366) of the Gaussian image. In another example, one filter is used, and the Laplacian image (449-469) is based on the filtered version (441-461) of the Gaussian image and an upsampled downsampling (446-466) of the filtered version of the Gaussian image. By forming the Laplacian images (349-369, 449-469) from the filtered Gaussian images (341-361, 441-461), the aliasing conventionally produced by filtering the Laplacian images is substantially reduced.
