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.
