Data which are sampled more densely than the Nyquist limit in k-space are weighted prior to reconstruction by the inverse of the local sampling density. This work considers the effects of weighting data that are sampled less densely than the Nyquist limit. It specifically analyzes azimuthally unders

The gated MRI method gives us several sets of cross-sectional images on transverse, coronal, and sagittal planes of the heart in a cardiac cycle. In this paper, a method to reconstruct 3-D shapes of each part of the heart (i.e., left ventricle, left atrium, right ventricle, right atrium, aorta, and
## Abstract New, rapid two‐ and three‐dimensional imaging sequences based on steady‐state gradient echoes and projection‐reconstruction (PR) techniques are proposed. Quantitative studies show that fast PR sequences and classical, fast gradient‐echo Fourier transform sequences lead to identical cont
Linear prediction (LP) methods have been widely used for highresolution spectral estimation from finite Fourier samples. Their application to image reconstruction, on the other hand, has been markedly less successful. In this article, we present an improved LP method for high-resolution image recons
