Comparative evaluation of radiofrequency-treated and naturally aged rice (Var. Jhelum): Physicochemical, rheological, thermal, microstructural and glycemic characteristics.

This food science study compared freshly harvested, naturally aged, and RF-treated rice/paddy (Jhelum cultivar) to assess whether RF heating can simulate natural ageing. RF treatment reportedly induced ageing-like microstructural and functional changes similar to naturally aged rice. Reported outcomes included…

Helmet Radio Frequency Phased Array Applicators Enhance Thermal Magnetic Resonance of Brain Tumors.

This engineering study describes and simulates a helmet radio-frequency phased array applicator for Thermal Magnetic Resonance (ThermalMR), which combines MRI with targeted RF heating. Using EMF and temperature simulations in a phantom and human head model (including a modeled glioblastoma tumor volume), the authors…

Reduction of implant RF heating through modification of transmit coil electric field.

This engineering study describes modifying MRI RF transmit coil electric-field distributions to create electric field-free zones without substantially changing transmit sensitivity. Phantom experiments are reported to show reduced implant heating when a zero electric-field plane is aligned with the implant location.…

Influence of mashed potato dielectric properties and circulating water electric conductivity on radio frequency heating at 27 MHz.

This engineering study used experiments, computer simulations, and simplified analytical calculations to examine how mashed potato dielectric properties and circulating water electrical conductivity affect RF heating at 27 MHz. The authors report that higher circulating water conductivity and higher salt content in…
