With development of medical imaging technology, minimally invasive treatment technology on tumor under guidance of imaging system also achieves very big progress. The concept of treating tumor is changing with revolution. The damaging treatment is switching to building treatment, i.e. minimally invasive becomes the development direction of tumor treatment.

With advantages of rapid temperature increasing, strong tissues penetrating, multi-points ablation at the same time, larger ablation zones, real time temperature monitoring, accurate curative effect, microwave ablation is widely applied to treat liver tumor, lung tumor, uterine fibroids, bone tumor, kidney tumor, pancreas tumor, thyroid nodules, etc, which is the trend of tumor treatment in 21th century.
