    • The invention is directed to a method and a device for separate three-dimensional presentation of arteries and/or veins of a vessel system in a part of the body of a vertebrate by a rotation computer tomography. A masking run of the tomograph is undertaken without contrast media around the part of the body. Then two filling runs with contrast media are executed, with the venous phase of vessel contrasting during the first filling run occurring during the arterial phase of vessel contrasting of the second filling run and vice-versa. The data from the first and second filling run is combined into data sets from the arterial or the venous phases of the vessel contrasting of the filling runs. The data of the masking run is subtracted from the combined data sets to obtain final data sets for a three-dimensional presentation of the arterial or the venous vessel system.
    • 本发明涉及一种用于通过旋转计算机断层摄影在脊椎动物身体的一部分中分离地显示血管系统的血管和/或静脉的方法和装置。 在身体部分周围没有造影剂进行断层摄影术的掩蔽运行。 然后执行用造影剂的两次填充运行,在第一次填充运行期间血管对比的静脉期发生在第二次灌注运行的血管对比的动脉期期间,反之亦然。 来自第一次和第二次灌注运行的数据被组合成来自血管的动脉或静脉期的数据集,与填充运行相反。 从组合的数据集中减去掩蔽运行的数据,以获得用于动脉或静脉血管系统的三维呈现的最终数据集。

    • The invention relates to a method and a device for the separate three-dimensional representation of arteries and/or veins in a vascular system of the body by means of a C-arm biplanar system having two C-arms, which can each record a sequence of x-ray images from different projection angles during a mask or filler pass. With the filler pass, both C-arms record x-ray images, so that the x-ray images of the filler pass can be combined to form a first data record, which contains x-ray images from the arterial phase of the vascular contrasting and/or to form a second data record, which contains x-ray images from the venous phase of the vascular contrasting. This enables the arterial and venous phases to be reconstructed separately.
    • 本发明涉及一种用于通过具有两个C形臂的C臂双平面系统在身体的血管系统中分离地三维表示动脉和/或静脉的方法和装置,其可以记录一个序列 在掩模或填充物通过期间,来自不同投影角度的X射线图像。 利用填充通道,两个C臂记录X射线图像,使得填充通路的x射线图像可以组合以形成第一数据记录,其包含来自血管对比的动脉期的X射线图像 和/或形成第二数据记录,其包含来自血管造影的静脉期的X射线图像。 这使得能够分开重建动脉和静脉期。
