在电生理介入中引导导管的系统
摘要：
本发明涉及用于在电生理学过程中引导具有电极(21)的导管(20)的系统和方法。利用X射线设备(10)生成导管(20)和静止的参考导管(30)的图像序列(I1，...Ik，...)，并且与来自电极(21，31)的相关联电记录一起存储。然后可以从所述序列中选择对应于期望电记录图案(Ek)的参考图像(Ik)。在下一步骤中，在参考图像(Ik)上定位导管(20，30)的位置(T，R)，其中可以利用这个导管(30)在实际图像(I)上的位置来标识参考导管(30)的位置(R)。因此有可能也在实际图像上确定与导管(20)在参考图像(Ik)上的位置(T)相对应的、这个导管(20)的目标位置(T′)。可以最终在监视器(60)上标识所述目标位置(T)以协助将导管(20)引导到期望位置。
摘要（英）：

The invention relates to a system and a method for the guidance of a catheter (20) with an electrode (21) in an electrophysiological procedure. A sequence of images (I1, ... Ik, ...) of the catheter (20) and of a resting reference catheter (30) is generated with an X-ray device (10) and stored together with the associated electrographic recordings from the electrodes (21, 31). A reference image (Ik) may then be selected from said sequence that corresponds to a desired electrographic pattern (Ek). In a next step, the positions (T, R) of the catheters (20, 30) are localized on the reference image (Ik), wherein the position (R) of the reference catheter (30) can be identified with the position of this catheter (30) on an actual image (I). Thus it is possible to determine on the actual image also a target position (T') for the catheter (20) that corresponds to the position (T) of this catheter (20) on the reference image (Ik). Said target position (T) may finally be indicated on a monitor(60) to assist the guidance of the catheter (20) to a desired location.
