Cosmological Magnetic Fields by Parametric Resonance?

We investigate the possibility that electromagnetic fluctuations are amplified in expanding universe by parametric resonance, during the oscillatory regime of a scalar field to which they are coupled. We consider scalar electrodynamics and we find that electromagnetic fluctuations undergo exponential instabilities. This mechanism could have some relevance for the problem of large scale primordi...

Flow measurement by magnetic resonance: a unique asset worth optimising.

Users and manufacturers of cardiovascular magnetic resonance (CMR) systems have, potentially, an unrivalled asset. Phase contrast mapping of velocities through planes transecting the great arteries should provide the most accurate measurements available of cardiac output, shunt flow, aortic or pulmonary regurgitation and, indirectly, of mitral regurgitation. But the reality is that phase contra...

Optimal Sampling and Reconstruction Patterns for Magnetic Resonance Inverse Imaging and MR- Encephalography

Due to the low temporal resolution of the traditional MRI acquisition techniques employed for noninvasive hemodynamic-based functional brain imaging, gradient switching hinders the unambiguous detection of possible rapid nonhemodynamic changes [1]. A method is introduced in [1], which utilizes an array of parallel receivers to measure the functional contrast and dynamic statistical parametric m...

Sampling Theory and Adaptive Acquisition for Cardiac Magnetic Resonance Imaging

Heart disease is the leading cause of death in the western world. Early diagnosis, therapy management, and surgical intervention all require improved methods for cardiac imaging. Cardiac Magnetic Resonance Imaging (CMRI) holds the promise of replacing the gold standard of invasive catheterization and x-ray imaging by benign radio frequency waves and magnetic fields. However, MR imaging of the b...
