摘要：
An apparatus is provided for generating focused radio frequency. The apparatus may include multiple coils, and the multiple coils can be actuated so as to generate focused energy at a focal location within the body of a subject such as a human or non-human animal while minimizing heating at the skin of the subject. A first central coil and a second central coil that are placed adjacent to each other. The apparatus also comprises a first focusing coil and a second focusing coil. The first central coil and the second central coil are placed between the first focusing coil and the second focusing coil. The first focusing coil and the second focusing coil generate a radio frequency field that is 180 degrees out of phase from a radio frequency field generated by the first central coil and the second central coil.
