Among current modalities of biomedical and diagnostic imaging, MRI stands out by virtue of
its versatile contrast obtained without ionizing radiation. However, in various cases, eg …

Spiral acquisition schemes offer unique advantages such as flow compensation, efficient k-
space sampling and robustness against motion that make this option a viable choice among …

The idea of using parallel imaging to shorten the acquisition time by the simultaneous use of
multiple receive coils can be adapted for the parallel transmission of a spatially‐selective …

Data collection of MRI which is sampled nonuniformly in k‐space is often interpolated onto a
Cartesian grid for fast reconstruction. The collected data must be properly weighted before …

For certain medical applications resampling of data is required. In magnetic resonance
tomography (MRT) or computer tomography (CT), eg, data may be sampled on …

A variable‐density k‐space sampling method is proposed to reduce aliasing artifacts in MR
images. Because most of the energy of an image is concentrated around the k‐space center …

While radial 3D acquisition has been discussed in cardiac MRI for its excellent results with
radial undersampling, the self‐navigating properties of the trajectory need yet to be …

The Fourier Transform (FT) is one of the most important Signal processing techniques in use
today. In particular, it finds a number of uses in medical imaging, including reconstruction of …

Ultra‐short echo time (UTE) MRI requires both short excitation (∼ 0.5 ms) and short
acquisition delay (< 0.2 ms) to minimize T2‐induced signal decay. These requirements …

A novel approach that uses the concepts of parallel imaging to grid data sampled along a
non‐Cartesian trajectory using GRAPPA operator gridding (GROG) is described. GROG …
