METHOD AND DEVICE FOR GENERATING A COMPLETE 3D REPRESENTATION OF AN OBJECT FROM A PARTIAL SIGNAL

A method for generating an adjusted (or augmented) 3D representation of an object based on a reference 3D source representation compliant with a source imaging modality and a plurality of reference target images compliant with a target imaging modality and establishing meaningful anatomical correspondences between the 3D object representation and the object's 2D partial/sparse view, including: obtaining, from reference target images, corresponding source images compliant with the source imaging modality; obtaining a sparse 3D source representation whose 2D sections correspond to the obtained source images; determining, from the reference 3D source representation and the sparse 3D source representation, a deformation field to be applied to voxels of the reference 3D source representation to register 2D sections of the reference 3D source representation with corresponding 2D sections of the sparse 3D source representation; obtaining the object's adjusted 3D representation by applying the deformation field to the 3D reference source representation.
