摘要： In three-dimensional X-ray imaging, with C-arm systems, scan setup has to be performed manually under fluoroscopic control. According to an exemplary embodiment of the present invention, a scan planning system for planning a data acquisition process is provided, which is adapted to predict a field of view to be reconstructed and an image quality in the field of view with respect to the actual three-dimensional scan parameter set and previously acquired images or other information. The scan planning system may be accomplished by a stand control unit.

摘要： A method and an apparatus for selectively and interactively processing data sets is proposed. A first data set is gathered and a second data set is gathered. A first feature is selected interactively from the first data set. After the selection, the first feature is brought in correspondence with a second feature in the second data set during an identification step. The first feature, the second feature and combinations thereof can be visualized.

摘要： The invention relates to a system and a method for the guidance of a catheter (20) with an electrode (21) in an electrophysiological procedure. A sequence of images (I1, ... Ik, ...) of the catheter (20) and of a resting reference catheter (30) is generated with an X-ray device (10) and stored together with the associated electrographic recordings from the electrodes (21, 31). A reference image (Ik) may then be selected from said sequence that corresponds to a desired electrographic pattern (Ek). In a next step, the positions (T, R) of the catheters (20, 30) are localized on the reference image (Ik), wherein the position (R) of the reference catheter (30) can be identified with the position of this catheter (30) on an actual image (I). Thus it is possible to determine on the actual image also a target position (T') for the catheter (20) that corresponds to the position (T) of this catheter (20) on the reference image (Ik). Said target position (T) may finally be indicated on a monitor (60) to assist the guidance of the catheter (20) to a desired location.

摘要： A method of analyzing a tube system in particular by image processing of images of the tube system is provided by the present invention. In order to achieve a simulation of a medium flow through a calculated tube model, the present invention gathers a tube model from a specific tube data set. By defining the necessary parameters of a virtual injection of the medium by the user, the medium flows through the model. Using this displayed simulation for generating at least two images leads to an artificial image sequence that might support a person, which wants to examine a real structure, that corresponds to the calculated model. This might be seen in.

摘要： Adaptively controlling an imaging system (200, 205) includes constructing model feature characteristics (105) of a process over time, determining parameters and commands (110) for controlling the imaging system for each state of the process, performing data acquisition (120) for the process, extracting current features (130) of the process from the acquired data, matching (135) the current features (130) with the model feature characteristics (105) to determine a state of the process (140), and controlling the data acquisition based on the state of the process to produce optimized data.

摘要： An apparatus includes an imaging probe and is configured for dynamically arranging presentation of visual feedback (144) for guiding manual adjustment, via the probe, of a location, and orientation, associated with the probe. The arranging is selectively based on comparisons (321) between fields of view of the probe and respective results of segmenting image data acquired via the probe. In an embodiment, the feedback does not include (175) a grayscale depiction of the image data. Coordinate system trans formations corresponding to respective comparisons may be computed. The selecting may be based upon and dynamically responsive to content of imaging being dynamically acquired via the probe.
