*3.2. BR Numerical Dosimetry*

The induced electric field distributions inside the different anatomical models for both exposure scenarios (#2 and #3) and both coil positions (aligned and misaligned) are reported in Figures 6 and 7, respectively. These figures show that the ICNIRP-BR is never exceeded, except for a small portion of the wrist when the lying posture on the ground floor is considered. However, it is worth noting that ICNIRP suggests determining compliance against a <sup>2</sup> <sup>×</sup> <sup>2</sup> <sup>×</sup> <sup>2</sup> mm<sup>3</sup> average volume and the 99th percentile of the peak induced electric field [6]. In this work, anatomical models with a voxel resolution of 2 mm have been considered, and therefore the only 99th percentile has to be computed. Nevertheless, the 99.9th percentile is evaluated as well since the 99th percentile has sometimes been shown to underestimate the compliance, especially in the case of localized exposures [13,25–30].

**Figure 6. E**-field distributions for exposure scenario #2 in the aligned (**a**) and misaligned (**b**) coil positions. *Elim* is the BR = 11.48 V/m (the green area is the portion where the BR is exceeded).

**Figure 7. E**-field distributions for exposure scenario #3 in the aligned (**a**) and misaligned (**b**) coil positions. *Elim* is the BR = 11.48 V/m (the green area is the portion where the BR is exceeded).

To better quantify these results, the values of the exposure assessment are summarized in Table 1, where *Emax* is the peak induced electric field, whereas *E*99.9 and *E*<sup>99</sup> are the 99.9th and 99th percentiles, respectively. As can be observed, when comparing the latter with the BR, the overexposure is always negative (at least −6 dB), meaning that the considered exposure scenarios are far from exceeding the ICNIRP-BR.
