Automatic misalignment correction in neuroimages using surface symmetry priors.
نویسندگان
چکیده
Many brain imaging procedures require the careful alignment of different sets of images obtained in the same individual. The available automatic methods for brain alignment are susceptible to improvement. This paper discusses briefly a new automatic method to reinstall the tilted orientation of head images, using surface symmetry as a prior.

Employing symmetry features for automatic misalignment correction in neuroimages.
A novel method to automatically compute the symmetry plane and to correct the 3D orientation of neuro-images is presented. In acquisition of neuroimaging scans, the lack of perfect alignment of a patient's head makes it challenging to evaluate brain images. By deploying a shape-based criterion, the symmetry plane is defined as a plane that best matches external surface points on one side of the...
متن کاملThe Exchange Rate Misalignment, Volatility and the Export Performance: Evidence from Indonesia
T his study investigates the short-run and long-run impact of real exchange rate misalignment and volatility on Indonesian export to the US by exploiting the disaggregated data of export volume. The proxy of real exchange rate misalignment was obtained by estimating the fundamental equilibrium exchange rate (FEER) model, and the exchange rate volatility measured by employing the GARC...
متن کاملPhoton Attenuation Correction in Misregistered Cardiac PET/CT
PET-CT misalignment has been reported as a source of artefacts in cardiac PET/CT due to a biased photon attenuation correction. Using the data from 28 cardiac PET/CT rest/stress examinations, PETCT misalignment was corrected using three different methods: manual registration, automatic mutual information based image registration and an emission-driven correction algorithm. The clinical effects ...
متن کاملTwo-plane automatic balancing: a symmetry breaking analysis
We present an analysis of a two-plane automatic balancing device for rotating machinery. The mechanism consists of a pair of races that contain balancing balls which move to eliminate imbalance due to rotor eccentricity or principal axis misalignment. A model is developed that includes the effect of support anisotropy and rotor acceleration. The symmetry of the imbalance is considered, and tech...
متن کاملCalculations of Dihedral Groups Using Circular Indexation
In this work, a regular polygon with $n$ sides is described by a periodic (circular) sequence with period $n$. Each element of the sequence represents a vertex of the polygon. Each symmetry of the polygon is the rotation of the polygon around the center-point and/or flipping around a symmetry axis. Here each symmetry is considered as a system that takes an input circular sequence and g...
