讨论了用于热疗的磁共振电路的制作和表征。由电感器和电容器的闭合连接组成的谐振电路通过外部施加的磁场升高其温度。由于谐振电路被有效地加热，所以它可以被磁共振成像（MRI）的弱RF磁场激励。通过将铁氧体磁芯用于电感器，提高了电路的温升效率，这归因于植入物尺寸的小型化。
Fabrication and characterization of a resonant circuit as magnetic device for hyperthermia treatment are discussed. The resonant circuit consisting of a closed connection of an inductor and a capacitor raised its temperature by an externally applied magnetic field. As the resonant circuit was heated efficiently, it could be excited by a weak RF magnetic field of magnetic resonance imaging (MRI). By using a ferrite core for the inductor, the efficiency of temperature rise of the circuit was improved, which attributed to the miniaturization of the implant size.
