Figure 3.
Quadrature transmit fields and specific absorption rates. Simulated fields in sagittal and transverse orientation were normalized with respect to 1 W of tissue dissipated power. The PZT blocks (schematically shown as dotted black lines) increase the transmit efficiency in the spine region compared with no blocks (a) to (d) and decrease the maximum SAR10 (e,f) in the body model Duke. The effects are similar in the body model Ella (g) to (l), but the increase in transmit efficiency is more pronounced.
