Topological Correction of Brain Surface Meshes Using Spherical Harmonics
A brain surface reconstruction allows advanced analysis of structural and functional brain data that is not possible using volumetric data alone. However, the generation of a brain surface mesh from MRI data often introduces topological defects and artifacts that must be corrected. We show that it is possible to accurately correct these errors using spherical harmonics. Our results clearly demo...
متن کاملTitle: Topological Correction of Brain Surface Meshes Using Spherical Harmonics
Surface reconstruction methods allow advanced analysis of brain data beyond what can be achieved using volumetric images alone. For instance, signals from distinct functional areas within the cortical sheet can be aligned, averaged and compared across subjects, while correctly modeling the folded geometry of the cortex. Even so, automated generation of cortical surface meshes from MRI data ofte...
متن کاملUsing Spherical-Harmonics Expansions for Optics Surface Reconstruction from Gradients
In this paper, we propose a new algorithm to reconstruct optics surfaces (aka wavefronts) from gradients, defined on a circular domain, by means of the Spherical Harmonics. The experimental results indicate that this algorithm renders the same accuracy, compared to the reconstruction based on classical Zernike polynomials, using a smaller number of polynomial terms, which potentially speeds up ...
متن کاملAmygdala Surface Modeling with Weighted Spherical Harmonics
Although there are numerous publications on amygdala volumetry, so far there has not been many studies on modeling local amygdala surface shape variations in a rigorous framework. This paper present a systematic framework for modeling local amygdala shape. Using a novel surface flattening technique, we obtain a smooth mapping from the amygdala surface to a sphere. Then taking the spherical coor...
متن کاملEncoding Cortical Surface by Spherical Harmonics
There is a lack of unified statistical modeling framework for cerebral shape asymmetry analysis in literature. Most previous approaches start with flipping the 3D magnetic resonance images (MRI). The anatomical correspondence across the hemispheres is then established by registering the original image to the flipped image. A difference of an anatomical index between these two images is used as ...
