Abstract:
An MRI antenna comprising:a first coaxial cable unit comprising a first inner conductor with first and second ends and a first outer conductor substantially surrounding the first inner conductor, the first outer conductor having first and second ends, the first coaxial cable unit having a concave curvature facing a first direction; and a second coaxial cable unit comprising a second inner conductor with first and second ends and a second outer conductor substantially surrounding the inner conductor, the second outer conductor having first and second ends, the second coaxial cable unit having a concave curvature fig a second direction opposite the first direction; wherein: the concave curvature of the first and second coaxial cable units generally face each other to define a region between the first and second coaxial cable units for receiving a body part, the first end of the first inner conductor is to be electrically connected to the first end of the second inner conductor through a first capacitor and the first end of the first outer conductor is to be electrically connected to the first end of the second outer conductor through a second capacitor, the second end of the first inner conductor and the second end of the second inner conductor are unconnected to each other and the second end of the first outer conductor and the second end of the second outer conductor being unconnected to each other, and first and second outer conductors provide an output of the antenna.
