Both images were taken using Doty CP Litzcage at 750 MHz. The CP litzcage dimensions were 21 mm diameter by 20 mm window length. The Doty Litzcage coil was used inside Bruker gradients of 40 mm ID in a vertical bore magnet. The sample was contained in an 18 mm sample tube. Images Courtesy of Dan Plant, University of Florida. Doty RF Litzcage Coil
Doty Litzcage coils combine (1) the Circular-Polarization (CP) of rf birdcage coils, (2) the insulated crossovers of the Doty linear Litz coil, and (3) a novel symmetrizing network to provide extraordinary B1 homogeneity, superior S/N, and exceptional simplicity in tuning to widely varying samples. How
does a Litzcage compare to
a Birdcage, • Much Easier Tuning. Easily tuned and matched to a wide range of samples. Tuning range is typically an order of magnitude greater. • B1 homogeneity is typically 10-40% better. • SNR is at least 10% higher – up to 30% higher. • Substantial cost advantage. What does it take to make the best MRI volume coils? Decades
of experience, bold creativity, and the most advanced simulation tools
