In parallel-beam tomography, the virtual alignment method plays an important role in obtaining an ideally aligned reconstruction of a rigid specimen. Furthermore, the method has been developed for elastic specimens with specific motions such as periodic motion, regular expansion or contraction, and elliptical expansion or contraction to obtain a sinogram with an ideal sinogram pattern by transforming an elastic-type projection image set into a rigid-type projection image set satisfying the Helgason-Ludwig consistency condition. In this article, we present a method to convert a combined elastic specimen to a rigid specimen using the virtual multi-alignment method that allows us to obtain an ideally multi-aligned reconstruction of a combined elastic specimen.
在平行束断层扫描中，虚拟对准方法在获得刚性样本的理想对准重建方面发挥着重要作用。此外，该方法已针对具有特定运动的弹性样本进行了开发，例如周期性运动、规则的膨胀或收缩以及椭圆形膨胀或收缩，通过将弹性类型的投影图像集转换为满足Helgason-Ludwig一致性条件的刚性类型投影图像集，以获得具有理想正弦图模式的正弦图。在本文中，我们提出了一种使用虚拟多重对准方法将组合弹性样本转换为刚性样本的方法，该方法使我们能够获得组合弹性样本的理想多重对准重建。
