A Study on the Physical Mechanisms of Hyperthermia Technology in Medical Physics
Abstract
Hyperthermia technology falls within the domain of medical physics interventional oncology and tissue ablation. Focusing on the
issues of heat generation, focusing, diffusion, and dose control within human tissues, this paper analyzes its physical mechanisms from three
perspectives: electromagnetic coupling heat generation, acoustic beam focusing thermal effects, and thermal field conduction regulation. It
further proposes comprehensive application approaches, including target zone temperature control in electromagnetic hyperthermia, precise
positioning in ultrasound thermal ablation, and thermal field monitoring with dose optimization. The efficacy of hyperthermia is not solely
dependent on the type of heat source but is also influenced by factors such as the dielectric properties of tissues, acoustic parameters, blood
perfusion, and temperature field distribution. Enhancing physical modeling, real-time monitoring, and dose feedback can improve the precision and safety of hyperthermia.
