| 摘要 |
A cancer thermotherapy apparatus of the present invention has an ortho-hexahedral cavity resonator and a loop antenna on a upper inner wall surface of the cavity resonator. The loop antenna is attached so that its loop face can be parallel to two side inner wall surfaces which are opposed each other, and orthogonal and adjacent to the upper inner wall surface. A high frequency electric power introduced into the cavity resonator is resonated in the parallel direction to the side wall surfaces on an excited mode with a constant electric field intensity along the side wall surfaces. A human body is set in the direction parallel to the side inner wall surfaces in the cavity resonator, and the resonated high frequency electric power is applied to the human body.
