چکیده
Figure 1: Variable FOV sampling patterns and resulting PSFs: (top) 2D PR elliptical FOV, (middle) PROPELLER oval FOV, (bottom) 3D PR cylinder with an elliptical base. Introduction: Radial-based imaging trajectories, such as projection-reconstruction, cones, and PROPELLER, have many applications [1-4] because of their increased robustness to motion and flow over Cartesian trajectories, and support for shorter TEs and TRs. We have developed new methods that design these trajectories for variable field-of-view (FOV) shapes and sizes.

Numerical Simulation of 1D Linear Telegraph Equation With Variable Coefficients Using Meshless Local Radial Point Interpolation (MLRPI)
In the current work, we implement the meshless local radial point interpolation (MLRPI) method to find numerical solution of one-dimensional linear telegraph equations with variable coefficients. The MLRPI method, as a meshless technique, does not require any background integration cells and all integrations are carried out locally over small quadrature domains of regular shapes, such as lines ...

متن کاملClassifying the Epilepsy Based on the Phase Space Sorted With the Radial Poincaré Sections in Electroencephalography
Background: Epilepsy is a brain disorder that changes the basin geometry of the oscillation of trajectories in the phase space. Nevertheless, recent studies on epilepsy often used the statistical characteristics of this space to diagnose epileptic seizures. Objectives: We evaluated changes caused by the seizures on the mentioned basin by focusing on phase space sorted by Poincaré sections. Ma...
