Figure 6: — a) Schematic of the experimental setup of the tissue equivalent gel phantom exposed to an AMF amplitude of 3 kA/m (rms) generated by the three-piece Maxwell-type induction coil and cooled with water jacket at 20 °C for 20 minutes. Transient temperature measurements were carried out at 6 locations (denoted by ‘x’ in the figure) beginning at the gel center (r = 0) and at 1 cm increments towards the outer edge. b) Temperatures measured in gel phantom with fiber optic probes when exposed to 3 kA/m field. Radial dependence of non-specific heating in tissue mimicking gel phantom placed inside the circulating water jacket at room temperature is demonstrated. c) 2D Temperature distribution at the center of the simulation geomtery when exposed to an AMF amplitude of 3 kA/m (rms) at 150 kHz for 20 minutes. The FEA simulations of temperature distribution in gel phantom due to non-specific heating arising from eddy currents predict similar trends as measured experimentally as shown in (b).
