Localized hyperthermia has been thought as an ideal means for a non-invasive or micro-invasive cancer therapy,and as an alternative treatment of conventional modalities of X-radiation, chemotherapy and surgery. In last decades,some technologies of electromagnetic hyperthermia have been developed and launched onto market. Based on different electromagnetic frequencies and physical theories, there are three main developed systems in terms of electromagnetic hyperthermia, namely, RFA (Radio Frequency Ablation), Magnetic Induction Ablation (MIA) and Microwave Ablation (MWA). RFA has been thought as the most mature one from the point of practical view in the current market of medical equipment.

Even being developed slowly, recently, electromagnetic hyperthermia technologies employing either Magnetic Induction Ablation or Microwave Ablation have caused attention in medical engineering field again. The main reason of recalling them back is the requirement of treatment quality for patients, especially considering how to ease their pain during operation. On the other hand, how to lower the working pressure for doctors while using the ablation system is crucial as well.

In this paper, the general review of the working theories and technical elements of the interested electromagnetic hyperthermia technologies is to be described firstly. Though these electromagnetic hyperthermia technologies are based on quite fundamental physical theories, they face with complex and difficult issues in terms of multiple engineering realizations. Namely, issues of material selection (say, bio-toxic problem), tooling techniques, and temperature control methods, etc., may be encountered, individually or simultaneously. Another important factor of commercializing electromagnetic hyperthermia systems is the high cost of disposable materials, for example, the used-for-once MWA antennas, which are not affordable for normal tumor patients.

Conclusively speaking, the presentation is to report the associated experiences of developing electromagnetic hyperthermia in last years. The presented results are supposed to be helpful for audiences who are interested in these technical domains.
