Evaluation of temperature sensitive amorphous metal flakes for self-regulated hyperthermia

A fundamental study on the soft heating method for local hyperthermia is discussed. A heater made of temperature-sensitive amorphous metal flakes of various lengths was tested. The flakes were implanted in a phantom, and heating characteristics and temperature distribution established in the phantom were measured. The phantom test reveals that the flakes are able to heat a surround area of 5 mm. This 5 mm is considered as the therapeutical region. It is concluded that the soft heating device utilizing the flakes has a potential to be applied in clinical hyperthermia. >
