Abstract: The present invention relates to a CT imaging system as well as a method for CT imaging is provided. For CT imaging, in practice a scout scan and a main scan of a human subject may be performed. It has been found that a detector signal, provided by a detector which detects the X-ray radiation during the scout scan, may be used on the one hand for determining a respective scout image and on the other hand to determine the bone mineral density of the human subject. Although the scout scan is usually primarily performed for determining the scout image, it is of advantage, if the detector used for detecting the X-ray radiation during the scout scan is formed and/or configured to detect X-ray radiation of a first energy spectrum and to detect X-ray radiation of a different, second energy spectrum. In this case, the detector can provide more precise information about the scout region of the human subject and resulting therefrom in a more precise determination of the bone mineral density.

Abstract: A device for visualizing a 3D object includes a processor configured to provide an image in a 2D projection plane, and to project an initial 3D object from an initial plane with an inverse projection transformation in the 2D projection plane of the image to achieve an inverse 2D object. The inverse projection transformation is a projection transformation, where a vanishing point is at the other side of the 2D projection plane than the initial object. The processor is further configured to point-mirror the inverse 2D object to achieve a mirrored non-inverse 2D object, and to project the mirrored non-inverse 2D object back to the initial plane to provide a corrected 3D object. Further, the processor is configured to project the corrected 3D object again to the 2D projection plane of the image to provide a final 3D object appearing to be non-inversely projected.

Charge-sharing-corrected detection values are determined based on the provided detection pulses, wherein for determining a charge-sharing-corrected detection value for a detection pixel of a cluster only detection pixels of the same cluster are considered. This allows for a relatively high detective quantum efficiency, wherein the technical efforts for providing the charge sharing correction can be relatively low.

Abstract: An ultrasonic diagnostic imaging system produces contrast enhanced images which are processed differently during different stages of contrast agent wash-in. During an initial stage of contrast wash-in, imaging is done using pixels processed by maximum intensity detection, to better reflect the rapid change in contrast intensity. During a later stage of contrast wash-in, time averaged processing is used to diminish the effects of noise and motion on the pixel values. During an intermediate period of peak enhancement, a combination of both pixel values processed by both techniques is used. In another aspect, a wash-in period can be characterized by an appearance stage, a growth stage and a peak stage, in which contrast pixel data is adaptively processed in different ways during these periods.
