Abstract
A diathermy apparatus has a power circuit operative at a selected, fixed frequency. An applicator head, for providing therapeutic treatment, has an irradiating portion. A transmission line connects the power circuit and applicator head, and is of a length so that, at the frequency, a selected minimum power is delivered to the applicator head when unloaded, the length further being such that a selected maximum amount of power is delivered to the applicator head when it is in a loaded position in close proximity to a patient load. The diathermy apparatus also includes a cabinet and portable base, wherein the portable base mounts the applicator head, and provides a carriage for the cabinet. The applicator head has an internal fan for cooling components of the applicator head. A display is provided for displaying the actual power consumed by the patient load. A processor independently controls the pulse modulator and power circuit in digital increments on a selected scale.
