Three dimensional k-space trajectory design using genetic algorithms
(ELSEVIER SCIENCE INC, 2003)
Image quality and total scan time in MRI are determined in large part by the trajectory employed to sample the Fourier space. Each trajectory has different properties like coverage of k-space, scan time, sensitivity to ...
Fast three-dimensional k-space trajectory design using missile guidance ideas
(WILEY, 2004)
Three-dimensional (3D) k-space trajectories are needed to acquire volumetric images in MRI. While scan time is determined by the trajectory efficiency, image quality and distortions depend on the shape of the trajectories. ...
Undersampling k-space using fast progressive 3D trajectories
(WILEY, 2005)
In 3D MRI, sampling k-space with traditional trajectories can be excessively time-consuming. Fast imaging trajectories are used in an attempt to efficiently cover the k-space and reduce the scan time without significantly ...

Multiple-Aspect Trajectory Similarity Measuring
(Florianópolis, SC., 2019)
An index for moving objects with constant-time access to their compressed trajectories
(Taylor & Francis, 2020)
As the number of vehicles and devices equipped with GPS technology has grown explosively, an urgent need has arisen for time- and space-efficient data structures to represent their trajectories. The most commonly desired ...
An initial value representation for the coherent state propagator with complex trajectories
(Elsevier Science BvAmsterdamHolanda, 2010)
Real trajectories in the semiclassical coherent state propagator
(Amer Inst PhysicsMelvilleEUA, 2005)
A 3D trajectory for undersampling k-space in MRSI applications
(ELSEVIER SCIENCE INC, 2007)
Magnetic resonance spectroscopic imaging (MRSI) is a noninvasive technique for producing spatially localized spectra. MRSI presents the important challenge of reducing the scan time while maintaining the spatial resolution. ...
