Abstract
Official abstract text for this publication.
The invention concerns the reconstruction of a two-dimensional (2D) or three-dimensional (3D) image of an object, for example part of a region of interest in a patient, on the basis of a set of a one-dimensional or two-dimensional views respectively of the region of interest, taken from different positions by an imagining system around the region of interest. The invention finds particular application in medical imaging by tomography reconstruction of Few-View Tomography.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for processing images obtained by tomography or tomosynthesis, the method comprising: acquiring a plurality of 2D projection images of an object using an imaging system, the acquiring a plurality of 2D projection images of an object being defined by Rf=s, wherein s is a vector of the acquired projections, R is a projection operator which models the imaging system and f is a 3D image of the object to be reconstructed with knowledge of R and s; proc…
