Abstract :
The HELIOS ultrasound system is a large aperture multitransducer array designed to heat deep-seated tumors for hyperthermia therapy of cancer. The development of a treatment simulation program, which uses measured ultrasound beam data to calculate anticipated temperature distributions for various treatment configurations, is described. This program is used to evaluate the effectiveness of the HELIOS applicator in its original configuration, and to investigate the potential improvement from proposed system modifications. Results from this program are presented in terms of practical heating strategies and pretreatment planning schemes
