Iterative reconstruction is a method or group of algorithms used to reconstruct 2D and 3D images from the projections of an object. The technique differs greatly from the more ubiquitous filtered back projection (FBP) method.

对等距不等角的锥束扫面可制作图像切片，同时可进行FBP图像重建，效果不错。-The cone beam scanning surface with unequal pitch can produce image slices and reconstruct FBP images, and the results are good.
