This preprint presents a technical perspective on the limitations of conventional electromagnetic hyperthermia instrumentation and proposes a next-generation platform centred on metrology, digital control and programmable excitation. The work addresses the poor inter-laboratory reproducibility of specific absorption rate (SAR) measurements in magnetic nanoparticle-mediated hyperthermia, identifying key sources of variability such as indirect magnetic field estimation, incomplete spatial field characterisation, manual resonance tuning, single-point thermal monitoring and insufficient experimental datalogging. The proposed framework includes calibrated pickup-coil magnetic field measurement, spatial mapping of the excitation field inside the coil, operation above 2 MHz enabled by GaN power electronics, programmable amplitude and frequency control, multichannel thermal monitoring using IR sensors, fibre-optic probes and thermal cameras with region-of-interest analysis, automated sequential protocols and complete synchronised datalogging. The paper argues that electromagnetic hyperthermia should evolve from a manually tuned experimental procedure into a traceable, digitally controlled and data-rich research platform. Particular emphasis is placed on reporting magnetic flux density in millitesla, defining the nominal field as the mean value within the actual sample volume, decoupling frequency from power control in resonant systems, and establishing a minimum reporting dataset for future hyperthermia experiments.
