    摘要： A method of linking image coordinates to coordinates in a reference model is disclosed. The method includes acquiring a 2½D or 3D input image representing a body of a living being and including at least two image boundaries of at least two parts within said body, acquiring a 3D reference model representative of a reference living being describing in a reference model coordinate system at least two reference boundaries of the at least two parts within said body, and overlaying the reference model and the input image. The method further includes adjusting at least a portion of one of the reference boundaries and/or at least one of the image boundaries such that this reference boundary and this image boundary substantially coincide, while the adjusted reference boundary does not intersect with the remaining reference boundaries and/or the adjusted image boundary does not intersect with the remaining image boundaries.

    摘要翻译： 联图像的方法的坐标在一个参考模型的坐标是游离缺失盘。 三重三次转换的一组分层用于映射参考模型坐标到真实世界坐标，反之亦然。 这提供了一个统一的框架来比较，并结合不同的计算模型和不同的患者。 实际上，这bedeutet，DASS所有相应的解剖，所有患者点将在参考模型中的同一坐标。 盘方法游离缺失以及可被视为3D的分层空间标准化的方法医疗（例如CT，MR）E. G.的图像 胸和心脏由翘曲或图像体积到例如弹性变形以助图像比较 一个单位立方体在保持在图像体积的解剖结构的空间关系。 翘曲是由三三次插值完成，并通过与在单位立方体的控制点产生Bezier表面被引导在寻求一种方式并贝塞尔表面接近身体或器官的边界表面上移动。 到单位立方体登记原始体图像的转换后变得微不足道。 更完了，盘上游离缺失应用这种方法来心电图图形成像IST。

    摘要： A method for providing a representation of the distribution, fluctuation and/or movement of electrical activity through heart tissue, said method comprising: obtaining an ECG of the heart comprising said tissue; obtaining a model of the heart geometry; obtaining a model of the torso geometry; relating the measurements per electrode of the ECG to the heart and torso geometry and estimating the distribution, fluctuation and/or movement of electrical activity through heart tissue based upon a fastest route algorithm, shortest path algorithm and/or fast marching algorithm.
