Low-field magnetic resonance imaging (mri) for medical applications.

Determine the optimal use of the superconductive quantum
interference device (squid)/mri in low-field nmr. The
technical advantages are a simpler magnet, a convenient, low
cost magnet system for use in interventional procedures.

The technique of NMR is widely used for spectroscopic and imaging purposes in both industrial and medical sectors. Medical use includes imaging of humans for diagnostic purposes. The technique involves the use of a relatively high magnetic field, provided by superconducting magnets. The objective of the proposed research project is to reconsider the fundamental philosophy of MRI so as to obtain good quality MRI using low-field magnets. The aim is to consider the use of cryogenic and/or superconductive sensors to improve the signal-to-noise ratio and thus push the useful frequency range down to low fields in which magnet design, construction and operation are simpler. The best candidate for the censor amplifier is the superconductive Quantum interference device (SQUID). It has been routinely used for many years in low temperature NM, but its use for room temperature sources imposes some problems. The aim is to determine the optimal use of SQUID/NMR in this field. Keywords: low field NMR, SQUID/NMR, portable magnetic resonance imaging/MRI unit.
