Abstract:
1. An elongate intrabody MRI-antenna probe having opposing distal and proximal portions, the distal portion having a single continuous length conductor arranged in a stack of two or three closely spaced substantially flat loops, wherein the stacked loops cooperate to define a flat-stacked loop MRI receive antenna, wherein the probe distal portion is planar and the flat stacked loop antenna has a flat shape on the distal portion of the probe, wherein the probe comprises at least one conductor that extends from the flat stacked loop antenna to an MR Scanner interface that connects to an MR Scanner, wherein the substantially flat loops have a long side and a short side, the long side having a length that is between about 20-50 mm, the short side having a width that is between about 1-5 mm, and wherein the flat-stacked loop MRI receive antenna is configured to generate a substantially homogenous signal profile and detect signal a forward looking distance beyond a distal end of the probe of at least about 1 mm.
