Abstract

Elongate intrabody MRI-antenna probes include opposing distal and proximal portions. The distal portion includes at least one multi-turn conductor arranged as a stack of substantially flat loops, each with a substantially rectangular elongate shape. A flat loop can reside on each of a plurality of adjacent vertically stacked substantially planar layers, the flat loops cooperate to define a MRI receive antenna.
