Depth-spread performance of the proposed coils; Effect of tilting angle and accumulation of wire wrapped coils on S1/2 and d1/2. The circles represent the locations of the previously studied coils by Deng et al [25]. The solid and dashed lines show the best-fit curves for the circular and figure-8 types of coils, respectively. The red dots are the calibrations performed in this study in COMSOL to validate the simulation technique. The AT coils have an inner and outer diameter of 8 cm and 9 cm, respectively, with tilting angles ranging from 0° to 70° with 10° steps and winding layers of 2, 5, and 9.
