Capacitive versus Overlap Decoupling of Adjacent Radio Frequency Phased Array Coil Elements: An Imaging Robustness Comparison When Sample Load Varies for 3 Tesla MRI

Figure 5

(a) 1/g-factor maps (anterior-posterior) for the 5-ch CD PA coil and 5-ch OD PA coil on the 0.6 S/m phantom. The maximum and mean g-factor values are listed below each figure. (b) 1/g-factor maps (left-right) for the 5-ch CD PA coil and 5-ch OD PA coil on the 0.6 S/m phantom. The maximum and mean g-factor values are listed below each figure. (c) Difference between the 1/g-factor maps when subtracting the 5-ch OD PA coil from the 5-ch CD PA coil 1/g-factor maps on the 0.3, 0.6, and 0.9 S/m phantoms. This was done for the anterior-posterior and left-right directions.
