Open magnet with shielding |
摘要 |
<p>An open magnet useful in magnetic resonance imaging (MRI) applications. The magnet has two spaced-apart assemblies (12,20). Each assembly has a shielding coil (22,40) located longitudinally outward from a main coil (14,32) and a magnetizable pole piece (24,42) spaced apart from and proximate the main and shielding coils. The method of the invention generates a magnetic field in a first area (52) between the two assemblies while shielding a second area not between the two assemblies from a stray magnetic field by creating the previously-described open magnet. <IMAGE></p> |
