    Abstract: It is described a model-based estimation of the current contraction status (S) of a periodically contracting object such as a beating heart. Thereby, a characteristic feature that is directly related to the contraction status (S) is extracted from a current image (340) and subsequently compared to a model that gives the contraction status (S) of the heart in dependence on the characteristic feature. Thereby, an appropriate patient- individual model may be obtained e.g. from an ECG gated pre-interventional data set. A potential characteristic feature is the distance between two arbitrary reference catheters (341a, 341b, 342a, 342b) that are usually in a fix known standard position during a whole electrophysiological intervention. The knowledge about the current contraction status may be used to combine the current image with other images depicting the object in the same contraction status. Thereby, image elements, which depend on the contraction status and which are not viewable in the current image, may be made visible by overlaying different images depicting the object in one and the same contraction status.

    Abstract translation: 它描述了对周期性收缩对象（例如跳动心脏）的当前收缩状态（S）的基于模型的估计。 由此，从当前图像（340）中提取与收缩状态（S）直接相关的特征特征，并随后将其与根据特征特征给出心脏的收缩状态（S）的模型进行比较。 由此，可以获得适当的患者个体模型，例如， 来自心电门控的预干预数据集。 潜在的特征是两个任意参考导管（341a，341b，342a，342b）之间的距离，这两个参考导管在整个电生理干预期间通常处于固定的已知标准位置。 关于当前收缩状态的知识可用于将当前图像与描绘处于相同收缩状态的对象的其他图像组合。 由此，可以通过将描绘对象的不同图像叠加在同一收缩状态中而使得取决于收缩状态并且在当前图像中不可见的图像元素变得可见。

    Abstract: The invention relates to a method of determining a corresponding image of a moving object for a reference image from an image sequence which represents the motion as a sequence of states of motion. To this end, two motion signals, representing the development of the relevant motions, are examined for similarities. Using the similarity function thus obtained, that image in the image sequence can be determined which represents at least approximately the state of motion of the object which is represented in the reference image. Furthermore, the invention relates to a system which is suitable for carrying out the method as well as to a computer program and a computer program product enabling a data processing unit to carry out the method.

    Abstract: The invention relates to a method and a device for automatic testing of an X-ray system ( 2 ). The doors ( 5 a, 5 b) leading to the room ( 1 ) in which the X-ray system ( 2 ) is installed are monitored by way of sensors ( 4 a, 4 b). Furthermore, the state of the room ( 1 ) can be monitored by means of further sensors such as video cameras ( 3 ). Automatic testing of the X-ray system ( 2 ) while utilizing X-rays is started only if and for as long as all doors are closed and the other sensors do not indicate that a safe state is abandoned. The device may also include facilities for automatically positioning a phantom in the beam path. Such facilities may in that case include a phantom which is provided on a flexible foil.
