Abstract:
:A simple modification is presented for two commercially available hyperthermia applicators which dramatically improves the regulation and dynamic control of the temperature at the bolus/tissue interface. This alteration requires the addition of a variable speed pump, bubble trap, simple heat exchanger, and a few minor changes to the existing system. With this modified design, the water within the bolus is directly circulated and temperature controlled. The convective nature of the circulating system ensures uniform temperature throughout the extended bolus and increases the thermal energy transfer at the bolus/tissue interface. This modification also provides significantly improved flexibility in controlling the treatment temperature distributions since the bolus/tissue interface temperature can now be dynamically varied during a treatment, in addition to adjusting the applicator power output and frequency.
