METHOD FOR NON-INVASIVE ABLATION AND DESTRUCTION OF DIELECTRIC BODY SEGMENTS WITH LOSS AND APPARATUS FOR IMPLEMENTATION THEREOF Russian patent published in 2012 - IPC A61B18/04 A61B18/18 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical equipment and may be used for implementation of non-invasive ablation and thermal and thermomechanical destruction of limited areas inside biological bodies of non-uniform structure and other dielectric bodies with loss exposed to electromagnetic field or ultrasound. An apparatus comprises a generator, emitters on the surface of a reflection shield, an analogue-to-digital converter, a power splitter, a multiplex switch and a control unit for emitters. It is preceded by emitter alignment in a travelling-wave mode followed by alignment of each emitter on the specified focus points according to the special algorithm by varying complex incident wave amplitudes and phases; after the alignment, emission power is increased to a value required to perform ablation and destruction of the preset dielectric body segments.

EFFECT: group of invention provides optimal focusing in the pre-set point, minimal size of a focal spot and maximal concentration and focusing accuracy of the impinging field.
