k-Space tutorial: an MRI educational tool for a better understanding of k-space
A main difference between Magnetic Resonance (MR) imaging and other medical imaging modalities is the control over the data acquisition and how it can be managed to finally show the adequate reconstructed image. With some basic programming adjustments, the user can modify the spatial resolution, field of view (FOV), image contrast, acquisition velocity, artifacts and so many other parameters th...
متن کاملk-Space partition diagrams: a graphical tool for analysis of MRI pulse sequences.
A new type of graphical tool for explaining and analyzing magnetic resonance imaging pulse sequences is developed and illustrated. This tool combines the partition diagram, which shows the evolution of multiple echoes with the application of multiple RF pulses, and k-space graphs, which show the evolution of the transverse magnetization as gradients are applied. The strength of the new tool lie...
متن کاملk-t GRAPPA: a k-space implementation for dynamic MRI with high reduction factor.
A novel technique called "k-t GRAPPA" is introduced for the acceleration of dynamic magnetic resonance imaging. Dynamic magnetic resonance images have significant signal correlations in k-space and time dimension. Hence, it is feasible to acquire only a reduced amount of data and recover the missing portion afterward. Generalized autocalibrating partially parallel acquisitions (GRAPPA), as an i...
متن کاملFast Iterative Reconstruction for MRI from Nonuniform k-space Data
In magnetic resonance imaging (MRI), methods that use a non-Cartesian (e.g. spiral) sampling grid in k-space are becoming increasingly important. Reconstruction is usually performed by resampling the data onto a Cartesian grid. In this paper we compare the standard approach (gridding) and an approach based on an implicit discretisation. We show that both methods can be solved efficiently with t...
متن کاملSimple correction method for k-space trajectory deviations in MRI.
A method is presented to correct for the imperfections of spatial encoding gradients in MRI. The approach is simple and fast, can be performed with standard scanner hardware, and does not require separate measurements with reference phantoms. The new method, using the MR signal to accurately measure the k-space trajectory of the imaging sequence, allows for correction of gradient hardware imper...
