To evaluate the effects of thermal therapy quantitatively, the variation of blood perfusion rate during prolonged heating was estimated by measuring heat flux. The abdominal heating controller was used as a heating device. A heat flux sensor was installed between the heating disk of the abdominal heating controller and abdominal area. When the surface temperature was around 43℃, the obvious and gradual increment of heat flux was observed. By assuming quasi-steady state, the time variation of blood perfusion rate was estimated by an analytical solution of bioheat transfer equation. The experiment was conducted to four subjects and the amplification of blood perfusion rate were confirmed.
