Arbitrary Topology Shape Reconstruction from Planar Cross Sections
ments are usually obtained one slice at a time, where each slice is a 2D array of scalar values corresponding to meaIn computed tomography, magnetic resonance imaging and ultrasound imaging, reconstruction of the 3D object from the surements distributed over a plane passing through the 2D scalar-valued slices obtained by the imaging system is diffiobject. The set of planes generating the slices...
متن کاملShape reconstruction from unorganized cross-sections
In this paper, we consider the problem of reconstructing a shape from unorganized cross-sections. The main motivation for this problem comes from medical imaging applications where cross-sections of human organs are obtained by means of a free hand ultrasound apparatus. The position and orientation of the cutting planes may be freely chosen which makes the problem substantially more difficult t...
متن کاملReconstruction of Multi-Label Domains from Partial Planar Cross-Sections
We present a novel algorithm for reconstructing a subdivision of the three-dimensional space (given arbitrarilyoriented slices of it) into labeled domains. The input to the algorithm is a collection of nonparallel planar crosssections of an unknown object, where the sections might cover only portions of the supporting planes. (The information in the rest of these planes is, thus, “unknown.”) Ea...
متن کاملProvably Good 2D Shape Reconstruction from Unorganized Cross-Sections
This paper deals with the reconstruction of 2-dimensional geometric shapes from unorganized 1-dimensional cross-sections. We study the problem in its full generality following the approach of Boissonnat and Memari [BM07] for the analogous 3D problem. We propose a new variant of this method and provide sampling conditions to guarantee that the output of the algorithm has the same topology as the...
متن کاملTetrahedral meshes from planar cross - sections q
In biomedicine, many three-dimensional (3D) objects are sampled in terms of slices such as computed tomography (CT), magnetic resonance imaging (MRI), and ultrasound imaging. It is often necessary to construct surface meshes from the cross sections for visualization, and thereafter construct tetrahedra for the solid bounded by the surface meshes for the purpose of ®nite element analysis. In Ref...
