Full‐wave electromagnetic simulations have been employed to analyze the design approaches that allow for solving the problems preventing inductive performance of micro‐solenoidal RF probes and formation of strong and homogeneous magnetic fields inside probes at the studies of millimeter‐range sized objects in 14 T MRI scanners. In particular, the effects of non‐uniform coil wrapping on field homogeneity...
We present approaches to enhancing magnetic field uniformity produced by RF probes in high-field Magnetic Resonance Imaging (MRI) scanners by introducing compensating non-uniformities in the probe designs. Unconventional designs of RF probes for operating at 600 MHz in 14 T MRI scanners are demonstrated, including a solenoid coil with non-uniform wrapping and dielectric separators, a system of microstrip...
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...
