摘要： To make interventional instruments such as catheters more easily identifiable in X-ray images, the catheters are provided with marking elements which can be recognized in the X-ray image. Examples of marking elements are sphere-shaped and ring-shaped marking elements, the ring-shaped marking elements being able to identify the catheters in the manner of a barcode and so being able to make different catheters distinguishable from one another in the X-ray image.

摘要： The present invention relates to a device and a method for synchronizing an image capture device with a first image data set. The image capture device is used for recording a second image data set of a periodically moving area or object. Each first image data set contains information as to the point in time, relative to the periodically moving area or object, when recording took place. The device additionally acquires periodically recurring, current information of the area as well as information concerning the recording instant of the first image data set. From the periodically recurring information and the recording instant of the first image data set, a triggering instant is derived which controls at least one recording of the second image data set by the image capture device in such a way that the second image data set contains image data synchronized to the first image data set.

摘要： The invention is based on a new type of method which can be used to localize magnetizable small particles. According to the invention an invasive instrument, a catheter for example, is provided with a magnetizable marker, whereby a magnetic fluid is arranged in a fluid container. Such an invasive instrument can be localized during an invasive intervention on a patient by using a coil system which on the one hand generates an inhomogeneous basic magnetic field and on the other hand generates a superimposed temporally varying magnetic field. Previous localization methods, which are considerably more complex, can be dispensed with.
