Abstract: A method and an apparatus for focusing radio wave energy are disclosed. According to an embodiment of a present disclosure, a method for focusing radio wave energy includes obtaining one or more internal tomographic images of a subject. The method also includes converting the one or more internal tomographic images into one or more numerical models. The method also includes calculating one or more first focusing parameters. The method also includes obtaining an image of the subject by monitoring the subject. The method also includes determining whether a second focusing parameter exists among the one or more first focusing parameters. The method also includes determining a final focusing parameter. The method also includes irradiating a lesion existing inside the subject with the radio wave energy using the final focusing parameter.

Abstract: A method of focusing radio wave energy at a focusing target point, which is performed by a processor, may comprise: generating an electromagnetic numerical model of an object including the focusing target point; predicting radio wave focusing points inside the object using radio wave characteristic information of a radio wave radiation module and the electromagnetic numerical model; optimizing one or more focusing parameters such that radio wave energy reaching one or more unnecessary focusing points other than the focusing target point among the radio wave focusing points inside the object is reduced; and radiating radio waves based on the optimized focusing parameters.
