Iterative reconstruction 三维重建

Example showing differences between filtered backprojection (right half) and iterative reconstruction method (left half)

Iterative reconstruction refers to iterative algorithms used to reconstruct 2D and 3D images in certain imaging techniques. For example, in computed tomography an image must be reconstructed from projections of an object. Here, iterative reconstruction techniques are a better, but computationally more expensive, alternative to the common filtered back projection (FBP) method, which directly calculates the image in a single reconstruction step.
