An output digital k-clock signal generated by the integrated Mach-Zehnder interferometer and drive electronics can be used as a data acquisition sampling clock, with no further resampling in k-space required.
In the MLFMA, the far interactions between the well-separated groups are efficiently computed using the k-space integrations over the Ewald sphere.
A close inspection of (34) reveals the relationship between a line element in 4-space and its conjugate line in K-space
In the presence of respiratory motion, high quality MR images can be produced by combining k-space profiles of the same cardiac phases in ECG-gated MR acquisition [8].
The first method [5] defines the IR readout by a series of highly undersampled radial fast low-angle shot (FLASH) images with nonlinear inversion (NLINV) reconstruction [9], while the latter methods reconstruct all parameter maps directly from highly undersampled k-space data, bypassing the intermediate step of image reconstruction completely.
A primary challenge in accelerating MR imaging is how to reconstruct high-resolution images from undersampled k-space data.
It contains an introductory math chapter and discussion of the process of image creation, including the concepts of gradients, signal/image processing, and k-space, and artifacts.
1), the whole process of this paper starts from K-Space data.
(23) This is caused by abrupt truncation of the k-space data at the edges of the sampled region of k-space when high-contrast sharp edges are present in the image, resulting in "ringing" adjacent to sharp edges.
(i) We propose a strategy to introduce synthetic motion artefacts in k-space.
Parallel imaging is an emerging technique to accelerate the MR data acquisition by undersampling the k-space data at each channel in multichannel coil arrays [1, 2].
