Abstract
A heat therapy technique by which heat is applied to a limited skin area of a patient to penetrate the tissue and produce hyperthermia in an internal region underlying this area without, however, causing undue discomfort to the patient or damaging surface tissue. Applied to the skin area is heated air in a pulsatory air wave pattern whose relatively brief pulses flow at high velocity and are at a high temperature well above body temperature and whose static intervals between pulses are at a medium temperature somewhat above body temperature. As a consequence, heat transfer from the surface tissue toward the internal region takes place during the intervals, thereby reducing the temperature of the surface tissue and preventing it from reaching an unacceptable level despite the high temperature of the high-velocity pulses applied thereto.
