Abstract :
Local hyperthermia is usually administered by noninvasive microwave applicators which produce therapeutic temperatures only to depths of 2-3 cm. The deeper penetration theoretically possible with RF applicators is not realized because of the practical limitations of applicator dimensions. Temperature distributions are generally nonuniform due to the attenuation of power with depth, the nonuniformity of the RF or microwave field, and heterogeneities in blood flow and tissue. Improved applicator designs are needed to improve temperature distributions in local hyperthermia.<>
