    摘要： A method for detecting tubing in a radiographic image of a patient, executed at least in part by a control logic processor, obtains a radiographic image data for a patient and detects one or more possible tube segments in the image. At least one tubing candidate is formed by extending at least one detected tube segment or merging two or more detected tube segments.

    摘要： A method and a system for producing images of a subject, such as the heart of a human being. The method may comprise acquiring ultrasound images of the subject with a catheter comprising a position sensor. The method may also comprise capturing a plurality of 4D surface registration points in the acquired ultrasound images corresponding to points on the subject. The method may also comprise registering, in space and time, a high-resolution 4D model of the subject with the plurality of 4D surface registration points. The method may also comprise displaying high resolution, real-time images of the subject during a medical procedure based on the registration of the high resolution 4D model to the 4D surface registration points. Embodiments of the present invention are especially useful in left atrium ablation procedures.

    摘要： An image processing method of extracting the points of a path following a threadlike structure in an image (IP) formed by a grid of Potential points, comprises: a first processing step (4) of performing a first path-tracking operation using a front marching technique denoted Filiation Front Marching Technique (FFM) for supplying at least one First Track of the threadlike structure, formed by succeeding points denoted Fathers and Children, by marching a Front of points forwards from a fixed Start point (A) to a fixed End point (B), and a second processing step (5) of performing a second path-tracking operation using said Filiation Front Marching Technique for supplying a Best Path from one First Track by back propagating the Front starting at the End Point and going through already determined Children and Fathers until the Start Point is reached. An X-ray apparatus is proposed, having means for carrying out said method of improving the visualization of catheter guide-wire.
