Influence of external head cooling on the head, core body and blood temperatures using 3D whole-body model.

Purpose: The purpose of this study is to evaluate the impact of external head cooling on alleviating the heat stress in the human body by analyzing the temperatures of the core body (T), blood (T) and head (T) during exercise conditions using 3D whole body model.

Design/methodology/approach: Computational study is conducted to comprehend the influence of external head cooling on T, T and T. The Pennes bioheat and energy balance equations formulated for the whole-body model are solved concurrently to obtain T, T and T for external head cooling values from 33 to 233 W/m Increased external head cooling of 404 W/m is used to compare the numerical and experimental Th data.

Enhanced thermal effect using magnetic nano-particles during high-intensity focused ultrasound.

Collateral damage and long sonication times occurring during high-intensity focused ultrasound (HIFU) ablation procedures limit clinical advancement. In this reserarch, we investigated whether the use of magnetic nano-particles (mNPs) can reduce the power required to ablate tissue or, for the same power, reduce the duration of the procedure. Tissue-mimicking phantoms containing embedded thermocouples and physiologically acceptable concentrations (0%, 0.
