Abstract
The use of an externally located dipole array mounted upon a high dielectric material for heating biological tissues is disclosed. This dipole array provides improved flexibility and adaptability to varying tissue surface contours. The adjustable dipole antenna array or other type of electromagnetic antenna applicators provides an ability to adapt the heating pattern to meet the needs of the different tissue zones, applicator positions, and applicator mechanical scanning by adjusting individual power amplitude and phase to the various elements of the applicator array for controlling the heat distribution of heat in target tissue having areas of varying power absorption and cooling effect (blood flow). The array design may also include capacitively coupled metal elements in the form of strips, patches or tubes. The electromagnetic heating elements are attached to a transparent flexible dielectric fluid filled envelope, tube, or bag for viewing both the tissue surface being heated and positioning the applicators and temperature sensors. The flexibility of this array provides uniform heating of a diversity of surface contours. Also, an electromechanical positioning system for the applications allows the applicators to be selectively positioned in the tubes, and thereafter repositioned during treatment.
