2P5-11 Estimation of thermal distribution in tissue mimicking phantom made of carrageenan gel(Poster Session)

Abstract

In this study, a temperature visualization method with a tissue mimicking phantom was proposed. For the experiment, a tissue mimicking phantom was fabricated with carrageenan gel, which has high transparency for the visualization and also, of which acoustic characteristics are similar to those of human tissue. The thermochromic film was set on the surface including the acoustic axis, and the temperature elevations caused by the plane and the focused ultrasounds was visualized noninvasively. The visualized image provided quantitative data of the temperature elevation in the phantom through an image processing method. The results showed good agreement with the calculated results by using the bio-heat transfer equation with Fourier transformation.
