Abstract

The blood perfusion of some tumors is relatively low and poorly responsive to hyperthermia therapy. As a result, the blood flow provides relatively little heat sinking for tumors. We hypothesized that the thermal gradient between tumors and normal tissues could be increased by applying energy only during the pulsation of arteries. Tests of the hypothesis were done by using a finite element model, which simulated a tumor surrounded by normal tissues and this tumor received either continuous or pulsatile heat, together with the pulsatile blood flow. Our results indicated there was a thermal gradient of 8 °C between pulsatile and continuous powers on heat delivery. Established values for tissues and tumors were incorporated into this model and it facilitated us to predict the possible results on hyperthermia therapy.
