Characterizing and correcting gradient errors in non-cartesian imaging: Are gradient errors linear time-invariant (LTI)?
Non-Cartesian and rapid imaging sequences are more sensitive to scanner imperfections such as gradient delays and eddy currents. These imperfections vary between scanners and over time and can be a significant impediment to successful implementation and eventual adoption of non-Cartesian techniques by scanner manufacturers. Differences between the k-space trajectory desired and the trajectory a...
متن کاملGradient Convergence in Gradient methods with Errors
We consider the gradient method xt+1 = xt + γt(st + wt), where st is a descent direction of a function f : �n → � and wt is a deterministic or stochastic error. We assume that ∇f is Lipschitz continuous, that the stepsize γt diminishes to 0, and that st and wt satisfy standard conditions. We show that either f(xt) → −∞ or f(xt) converges to a finite value and ∇f(xt) → 0 (with probability 1 in t...
متن کاملAnalysis of gradient descent methods with non-diminishing, bounded errors
Implementations of stochastic gradient search algorithms such as back propagation typically rely on finite difference (FD) approximation methods. These methods are used to approximate the objective function gradient in steepest descent algorithms as well as the gradient and Hessian inverse in Newton based schemes. The convergence analyses of such schemes critically require that perturbation par...
متن کاملMR Gradient Estimation Using a Linear Time Invariant Model
Introduction: MRI applications such as functional MRI and dynamic imaging benefit from fast imaging trajectories such as spirals and 3D cones [1]. One complication of fast imaging with timevarying gradients is that the actual k-space trajectories are likely to deviate from the theoretical case due to gradient system imperfections. Reconstructing images with gradients measured on the scanner pro...
متن کاملDiagnosing and Correcting Systematic Errors in Spectral-Based Digital Imaging
A digital imaging system containing a calibration target, an image capture device, and a mathematical model to estimate spectral reflectance factor was treated as a spectrophotometer and as such subject to systematic and random errors. The systematic errors considered were photometric zero, photometric linear and nonlinear scale, wavelength linear and nonlinear scale, and bandwidth. To diagnose...
