    • Certain embodiments of the present invention provide a system and method for improved distortion measurement and compensation. Certain embodiments include selecting a set of sources on a surface of a volume, determining mutual inductances from the set of sources on the surface, and calculating distortion from the volume using the mutual inductances from the set of sources on the surface. In an embodiment, distortion is calculated using an integral method and/or a finite element analysis. The volume may be modeled as a simplified construct, such as a ring model, a coil array with straight line segments model, a polygon model, and/or dipole array model. The model may be adjusted based on the distortion calculated from the volume. Magnetic fields may also be used to calculate distortion. In an embodiment, an object may be tracked using a distortion mapping.
    • 本发明的某些实施例提供了用于改进失真测量和补偿的系统和方法。 某些实施例包括在体积表面上选择一组源,确定来自表面上的源集合的互感,以及使用来自表面上的源集合的互感来计算来自体积的变形。 在一个实施例中,使用积分方法和/或有限元分析来计算失真。 体积可以被建模为简化的构造,例如环形模型,具有直线段模型的线圈阵列,多边形模型和/或偶极阵列模型。 可以根据从体积计算的失真来调整模型。 磁场也可用于计算失真。 在一个实施例中,可以使用失真映射跟踪对象。
