Human Head RF Imaging Coils

1.5 T – 4.7 T

3 T Human Brain Image

This T2 image was taken with the first Doty rf Litzcage head coil.

Additional test results…

When we first introduced our Litzcage head coil, we had independent, same-patient comparisons of a prototype passive 3 T version (no internal preamps) to coils by the most respected competitors in the industry. These tests showed our Litzcage to have substantial advantages in robustness and tunability, dramatically better B₁ homogeneity, superior overall S/N, and a degree of openness previously unheard of in high-performance, high-field extremity coils.

IWe've also made a smaller diameter 3 T litzcage head coil designed for imaging in the Siemens Allegra imager and a 3 T double-tuned ¹H/³¹P hybrid CP head coil.
