The present invention relates to automatic absorption means positioning in X-ray image acquisition. To improve image quality and to optimize the radiation exposure of an object, optimal position for X-ray absorption means is provided. A first sequence () of X-ray images is acquired (). For each of the images, the optimal position () for X-ray absorption means is determined (). A second sequence () of X-ray images is associated 10 () with corresponding images of the first sequence. The determined optimal position for the absorption means () of the associated corresponding images of the first sequence () is selected for an acquisition of the second sequence (). Hence, a situation-specific database with optimized positions for the absorption means is generated on behalf of the first sequence in order to provide the generated position information for the actual acquisition of a 15 second sequence of images.

Automatic positioning of absorption means in X-ray image acquisition

The invention relates to a system and a method for producing an image of a physical object and to a computer program element and a computer readable medium. In order to provide improved stent boost subtract also showing wire state information, a system and a method are provided, the method comprising the following steps: a) tracking a predetermined first feature () and a predetermined second feature () in a first plurality () of first images (), which images reveal a first criterion (); and determining a first feature transform; and determining second feature distortion vector fields relative to the first feature transform; b) associating and recording second feature distortion vector fields corresponding to at least two phase attributes (); c) tracking the predetermined first feature () in at least one secondary image () which image reveals a second criterion; d) determining a first-feature-based inter-criterion the first-feature-based inter-phase transform and the second feature distortion vector fields corresponding to a matching phase attribute (); and f) generating a combined inter-criterion image () based on the restored physical distortion.

System and method for producing an image of a physical object

A medical viewing system with an X-ray image acquisition device for acquiring angiograms and interventional live images of vessels is adapted for generating a region of interest border into which an object referenced by an object-based registration process must extend in order to achieve an accurate registration of vessel trees extracted from the angiogram and the live images. The region of interest border is then overlaid onto the vessel tree images and the live images. The medical viewing system reminds the person accomplishing the intervention of the importance of pushing the object far enough into the image, while being discrete enough to be ignored if preferred, thus yielding in a reliable and precise road mapping processing.

An image of a physical object is produced by receiving a plurality of raw images, dividing the plurality of raw images into a first subset of primary images and a second subset of secondary images according to a predetermined criterion. From the first subset of primary images an intermediate image is determined while from the second subset of secondary images a mask image is determined. Afterwards a registration of the intermediate image and the mask image is performed by using direct registration of predetermined features present in the intermediate image and the mask image. A fused image of the physical object is generated out of the mask image and the intermediate image.
