- •
We improve the Landweber iteration algorithm for 3D ECT by two measures.
- •
We add an additional acceleration into the cost function.
- •
We apply an adaptive thresholding to the image reconstructed in each iteration.
- •
The two measures taken can reduce reconstruction time and artefacts obviously.
- •
The algorithm proposed has been evaluated by simulation and experiment.
