Modified design of the coil probe for high field MRI

Small RF coils for operating in Magnetic Resonance Imaging (MRI) 14T systems with Larmor frequency of 600 MHz for imaging seed assembles have been developed with the focus to improve the homogeneity of magnetic field inside the coils for obtaining higher image quality. The performed full-wave simulations have shown that uniformly wrapped coils fail to provide the desired field homogeneity, while non-uniform wrapping can be employed for achieving essentially more congruous field distributions.
