本文的目的是提出一种通用的方法来推导三维锥束层析成像的反演公式。从近似逆开始，我们使用扫描几何的对称性来导出重建核以导出快速算法。从真实的数据的重建表明，该方法能够产生可靠的图像，其中数据噪声尽可能地减少。
The aim of this paper is to present a general approach to derive inversion formulae for 3D cone beam tomography. Starting from the approximate inverse we derive reconstruction kernels using the symmetries of the scanning geometry to derive fast algorithms. Reconstructions from real data show the ability of the method to produce reliable images where the data noise is reduced as much as possible.
