Cross-correlation can be used to match 2D images in translation and in rotation. An extension to 3D mono-modality matching is presented. This process allows comparison of two sets of data along the same orientation. To decrease computation time, oblique projections of a 'wandering slice' are used. The precision is about +/- 0.2 degree in rotation and +/- 0.2 mm in translation. Some examples, applied to pre- and post-therapy comparison, are given.
互相关可以用于匹配二维图像的平移和旋转。本文提出了一种三维单模态匹配的扩展方法。该过程允许沿着相同方向比较两组数据。为了减少计算时间，使用了“移动切片”的斜投影。旋转精度约为±0.2度，平移精度约为±0.2毫米。给出了一些应用于治疗前后比较的示例。
