摘要

从连续横截面重建三维物体在许多医学和生物学应用中是重要的操作。强度插值可以从任意角度进行切片，并为各种目的提供准确的定量信息。然而，唯一可用的技术是直接的线性插值方法，这在技术上是不健全和没有根据的。提出了一种对两个连续截面上的两个感兴趣区域进行强度插值的方法。虽然强度是线性插值的，但在插值中所涉及的对应点是经过仔细选择的。实验结果表明，该方法优于直接方法。

Intensity interpolation for reconstructing 3-D medical images from serial cross-sections

Reconstructing three-dimensional objects from serial cross-sections is an important operation in many medical and biological applications. Intensity interpolation makes slicing from any arbitrary angle possible and also provides accurate quantitative information for various purposes. However, the only technique available is the straightforward linear interpolation method which is technically unsound and groundless. An intensity interpolation method for two regions of interest lying on two consecutive cross-sections is proposed. Although the intensity is interpolated linearly, the corresponding points involved in interpolation are carefully selected. The experimental results show that it is superior to the straightforward method.<>
