先前报道的断层扫描金属探测器，它是能够反转的位置和磁极化张量为一个单一的对象已经被修改，使得它是能够反转的位置和磁极化张量为多个对象。在本文中，术语“多个物体”是指多达三个独立的金属物体。本文的结果表明，该算法适用于垂直分离大于40 cm的物体，但可靠性随物体靠近或处于相同垂直高度而变化;多个物体的位置估计往往表现良好，但磁极化张量的估计变得较差。对象之间发生的相互作用是对此的一种可能的解释。
A previously reported tomographic metal detector which is capable of inverting the location and magnetic polarizability tensor for a single object has been modified such that it is capable of inverting the location and magnetic polarizability tensor for multiple objects. In this paper, the term'multiple objects' refers to up to three independent metallic objects. The results from this paper show that the algorithm works well for objects vertically separated by greater than 40 cm, however the reliability varies as objects are brought closer together, or are at the same vertical height; the estimation of position for multiple objects tends to perform well, but the estimation of the magnetic polarizability tensor becomes poorer. Interactions taking place between objects is presented as one possible explanation for this.
