Abstract:
A method of three-dimensional image reconstruction from a set of acquired two-dimensional images comprising:a subsampling of the set of acquired two-dimensional images is carried out so as to reduce the resolution of the acquired two-dimensional images; a first analytical algorithm of three-dimensional image reconstruction from acquired two-dimensional images of low resolution 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; and a second analytical algorithm of three-dimensional image reconstruction from acquired two-dimensional images is applied, by considering only the voxels of the reconstruction support; wherein the subsampling of an acquired two-dimensional image includes obtaining a low-resolution acquired two-dimensional image in which each pixel is composed of several pixels of the initial acquired two-dimensional image with the average gray level of the initial pixels being a gray level.
