ABSTRACT:
An RF probe for acquiring MR data comprising four loop means. There are first and second loop means that are substantially round, centered about a longitudinal axis of said probe and spaced apart substantially the length of said probe to define a cylindrical shape therebetween. There are third and fourth loop means being substantially saddle shaped spaced apart, oppositely disposed and extending between said first and second loop means. Conductors attached to said first and second loop means at points on said first and second loop means spaced apart by 180 degrees couple said third and fourth loop means to said first and second loop means to form a point of psuedo-saddle coils providing extremely homogenous signals.
