摘要： Superimposed X-ray and video images can be obtained by acquiring the respective images from the optically equivalent points in space. One or more mirrors may be used to acquire the images. Alignment of one camera with respect to the X-ray source may be achieved using images of reference points in space and their respective projections. Once the X-ray source and the video camera are positioned at the equivalent point in space, the resultant images can be superimposed through warping.

摘要： Compensation can be provided for rotational and translational motion of a detector relative to the X-ray source in a C-arm X-ray device by warping the image on the detector plane to a virtual detector plane and then mapping the image into three-dimensional space. By using a virtual detector, the computations required to reconstruct the three-dimensional model are greatly simplified.

摘要： A method is disclosed for combining a first image and a second image of an examination object, which images have an overlap region. A corresponding magnetic resonance scanner is also disclosed. In at least one embodiment, a superposed image is determined in the overlap region as a weighted superposition of the first image and the second image with a spatially variable weighting function. The first image and the second image are transformed on the basis of a comparison of the first image and/or the second image with the superposed image.
