Abstract
The invention concerns a method of three-dimensional image reconstruction from a set of acquired two-dimensional images. A subsampling is taken of the set of acquired two-dimensional images so as to reduce their resolution. A first analytical algorithm of three-dimensional image reconstruction from low-resolution (LR) acquired two-dimensional images is applied in order to obtain a low-resolution three-dimensional image. A reconstruction support is determined by selecting in the low-resolution three-dimensional image a set of particular voxels. One then applies a second analytical algorithm of three-dimensional image reconstruction from acquired two-dimensional images and considering only the voxels of the reconstruction support in order to obtain the high-resolution (HR) three-dimensional image.
