Magnetic resonance image reconstruction from non-equidistantly sampled data

In this paper, we consider the problem of magnetic resonance (MR) image reconstruction from non-uniformly sampled data acquired by echo-planar imaging (EPI) and spiral scan imaging (SSI) techniques. In EPI, mismatches in the timings of the odd and even echoes collected with readout gradients of alternating polarity will result in \N=2" ghosting in the reconstructed images. We propose a new meth...

Analytical Investigations in Magnetic Recording by Stephen

The Fourier method is used to provide new analytic solutions for idealized mathematical models of double-element shielded magnetoresistive (MR) recording heads. The general two-dimensional model allows analysis of various recording head configurations; a single pole head, a ring head, a dual stripe head and a differential head. The analysis accommodates both longitudinal recording (with no soft...

Magnetic sound recording

The first complete magnetic recorder (wire on a drum) was constructed in 1898 by Poulsen (Denmark). In 1938 the first recorders using plastic tape with an iron oxide layer were used. Since then, magnetic sound recording has become the most popular way of storing broadcast programmes for transmission at any time. Early attempts with temporary disc recording and photographic recording proved unsu...
