Abstract

We present in this paper a method for 2-D or 3-D tomographic reconstruction, when the angle of view of the projections is limited. This method uses a decomposition into constrained natural pixels which incorporates a priori information and a fast iterative inversion process. Numerical simulations show the importance of the added constraints, and prove the stability of the method in the presence of noisy data.
