    • The present invention provides a system and a method for imaging a volume of interest of a subject using ultrasound. The system comprises an ultrasound device adapted to acquire an image data set of the volume of interest of the subject and position information of a 3D ultrasound probe of the ultrasound device when the 3D ultrasound probe is placed at a position on the subject, the position information representing a position of the 3D ultrasound probe relative to at least three ultrasound sensors on an interventional device placed within the volume of interest, the at least three ultrasound sensors having predetermined relative positions at a distance from each other and not being aligned in a straight line; and an imaging device adapted to generate an image based on the image data set. According to the system, the position of the ultrasound probe may be derived in a convenient and low-cost manner.

    • A method and system for tracking a moving object. The object (10) is provided with one or more single-component sensors of a vector field. Generators of the vector field (40, 40', 40'', 42, 42', 42'', 44, 44', 44'') also are provided. Parameters of equations that relate the generated fields, as measured by the sensors, to the position of the object, but not to the orientation of the object, are determined either empirically or theoretically. The equations are solved to determine the position of the object without having to determine the orientation of the object. The scope of the invention also includes a helical guide wire wherein are integrally included one or more single-component sensors of a quasi-static magnetic field.
    • 用于跟踪移动物体的方法和系统。 物体(10)设置有一个或多个矢量场的单分量传感器。 也提供了矢量场(40,40',40“,42,42',42”,44,44',44“)的发生器。 通过传感器测量的生成场与参照物的位置关联的等式的参数,无论从经验上还是在理论上确定。 求解等式以确定对象的位置,而不必确定对象的方向。 本发明的范围还包括螺旋导丝,其中整体地包括一个或多个准静态磁场的单组分传感器。
