The effect on ΔT is shown versus particle radius with varying magnetic nanoparticle concentration (a) without MRI due to an alternating-sinusoidal magnetic field of 10 mT, (b) with a 0.2 T MRI field and an alternating-sinusoidal magnetic field of 10 mT and, (c) with a 0.2 T MRI field magnetic and a rotating field of 10 mT. For these result, the RF frequency is 300 kHz, ϕ = 0.002 and τ is a function of nanoparticle radius, as plotted in Figure 1. A 1 cm radius tumor is considered throughout.
