ABSTRACT:
An apparatus for the deep heating of cancers employing two single turn coaxial coils of varying diameter ranging from 2 inches to 6 inches which rotate synchronously in planes which are parallel to each other with the central axis of each coil lying in exactly the same line which is perpendicular to the plane of the coil. When the two coils are at 180.degree. from each other a line drawn through the central axes of both coils traverses the center of a tumor in the body which is to be heated and is not perpendicular to the two planes of rotation. The coils are placed so that the inner curvature of the rotating coil is tangential to the center of the tumor mass with the summated magnetic field of the rotating coils continuously heating the tumor with the maximum number of lines of magnetic force.
