摘要： In a method for positioning an X-ray image acquisition device a straight reference plane (30) intersecting a three-dimensional representation of the object, a center point (34) within the intersection of the object, a normal vector (38) to the reference plane and at least one tangential vector (40) within the reference plane are created. Thereafter, the reference plane, the object's frame of reference and the X-ray image acquisition's frame of reference are registered. At least one viewing direction derived from the normal vector (38) and/or at least one tangential vector (40) is defined, wherein the X-ray image acquisition device is adjusted to the geometrical parameters of the X-ray image acquisition device. Thereby, planned and stored optimal viewing directions may be made available by a single push of a button, leading to automatically positioning of the X-ray image acquisition device and a much faster adjustment of the live guidance image, thus resulting in less exposure of radiation as well as a less cumbersome adjustment procedure. Furthermore a more optimal deployment of the interventional devices can be reached, since they can be more accurately positioned.
摘要翻译：在用于将X射线图像采集装置定位为与物体的三维表示相交的直线参考平面（30）的方法中，在物体的交叉点内的中心点（34），法线向量（38）到参考平面和参考平面内的至少一个切向矢量（40）。此后，登记参考平面，物体的参照系和X射线图像获取的参照系。定义从法向量（38）和/或至少一个切向矢量（40）导出的至少一个观察方向，其中将X射线图像采集装置调整到X射线图像采集装置的几何参数。因此，可以通过单次按压按钮使计划和存储的最佳观看方向可用，导致X射线图像采集装置的自动定位和实时指导图像的更快调整，从而导致较少的辐射暴露以及较不麻烦的调整程序。此外，可以达到更好的部署介入装置，因为它们可以更准确地定位。
