ABSTRACT:
A non-contact type of deep-diathermy apparatus comprises a microwave source (1), a microwave radiator (2), a microwave focusing device (3), a temperature-measuring device (4) and a computer based control and display device (5). An output port of the microwave radiator (2) is spaced apart from a surface of a diathermized position of a medium to be diathermized by a predetermined distance. The microwave focusing device (3) is placed in front of the output port of the radiator (2) and attached to the output port of the radiator (2) for focusing the microwave from the radiator (2) on a point within the predetermined distance. This apparatus can be used to kill cancer cells or reduce their vitality in deep parts of the medium and will not cause the surface of the medium to be burnt.
