Heat Production During mNP Hyperthermia - applied on a Deep Seated Tumors

Recently, nano-particles (NP) hyperthermia emerged as one of the most promising technologies for the treatment of cancers at the cell level. Studies show that cancer cells accept and accumulate NP more preferable than normal cells [1]. We have shown in [1], that heat production mechanism for Dartmouth mNP cannot be hysteresis. In this paper, we present experimental SAR measurement for Dartmouth mNP and give simulation results taking in account viscous friction loss as the main mechanism of SAR production. We have modeled eddy current heat generation in phantom as well as in the realistic human model. Results show that the eddy current heat effect is the same order as in mNP, which exhibits necessity of mechanism for eddy currents minimization.
