摘要： An MRI system is presented utilizing a magnetic assembly of a kind which, when accommodated within a primary static reasonably homogeneous magnetic field created by the MRI system affects the static magnetic field to cause creation of a region of substantial non-homogeneity of the static magnetic field in the vicinity of the magnetic assembly. By this, a local static field gradient is created. The magnetic assembly comprises a passive magnetic element, which deforms a pattern of the static magnetic field, while not being a magnetic field source by to itself.

摘要： An imaging probe and method and an MRI system utilizing the same are presented. The probe comprises first and second magnetic field sources, and a receiver of NMR signals. The first magnetic field source creates a primary, substantially non-homogeneous, static magnetic field in a region of interest in a medium outside the probe. The second magnetic field source creates an external time-varying magnetic field, which when being applied to the region of the static magnetic field, is capable of exciting nuclei in an extended sub-region of this region and generating the NMR signals.
