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.

摘要： Cardiac roadmapping consists in correctly overlaying a vessel map sequence derived from an angiogram acquisition onto a fluoroscopy sequence used during PTCA intervention. This enhanced fluoroscopy sequence however suffers from several drawbacks such as breathing motion, high noise level, and most of all suboptimal contrast-enhanced mask due to segmentation defaults. This invention proposes to reverse the process and to locally overlay the intervention device as seen in fluoroscopy onto an optimal contrast-enhanced image of a corresponding cycle. This drastically reduces or suppresses the breathing motion, it provides the high image quality standard of angiograms, and avoids segmentation defaults. This proposal could lead to a brand new navigation practice in PCI procedures.

摘要： An apparatus and a method is proposed, for visualization of an object of interest together with a device being inside the object of interest. The apparatus comprises an image formation unit adapted for providing image information of the object of interest and the device, a processing unit and a display adapted for displaying the image, wherein the image is a combination of the image information of the device and the boosted image information of the object of interest. Here, the processing unit is adapted for performing the following steps: detecting and segmenting the device on the basis of image information provided by the image formation unit; wiping-out the image information of the device; detecting the object of interest on the basis of the provided image information; boosting the image information of the object of interest; re-inserting the image information of the device.

摘要： A method for dynamically visualizing coronary information and an apparatus adapted to implement such method is described. In a preferred embodiment of the method, first dynamic cardiac data is acquired during a first cardiac stage and second dynamic cardiac data is acquired during a second cardiac stage. Then, the two data sets are visualized continuously the in a superimposed presentation, wherein the first cardiac data and the second cardiac data corresponding to a same phase within the cardiac cycle are visualized simultaneously. In this way for example information about the vessel geometry may be immediately linked with information about the muscle irrigation or perfusion. Furthermore, this useful information may be displaid in a high-contrasted and low-noise presentation.

摘要： Wire tips and balloon/stent markers are the main landmarks used by cardiologists for navigation and precise stent placement under X-Ray fluoroscopy surveillance. These intra-coronary devices are semi radio-opaque. In some situations, their visibility can be extremely low. The claimed may help the cardiologists by detecting the objects and darkening them on the live X-Ray image to increase their visibility. The darkening processing takes into account the image properties around the objects or detection information in order to obtain a better contrast enhancement. This technique also avoids the introduction of disturbing artefacts when the object detection fails.
