The egg white phantom is a thermal lesion visualization phantom able to illustrate a thermal lesion. Itis often used to evaluate the performance of HIFU and is less expensive than the BSA phantom. This study determinedthe optimal phantom composition for evaluated therapeutic ultrasound machines by varying the egg white concentrationin the egg white phantom and demonstrated its utility as a therapeutic ultrasound phantom. The egg whitephantom at varying egg white concentrations (10-40% in 10% intervals) was fabricated, and its thermal propertiesand acoustic properties were assessed. In addition, the size and shape of the formed lesion were compared betweenthe egg white phantom and bovine liver tissue according to the electrical power. The results showed that 30% eggwhite phantom was optimal for the performance evaluation due to its thermal and acoustic properties. The generatedthermal lesions formed sequentially as a cigar, ellipse, tadpole, and cone shapes according to the electrical power;a similar tendency was observed in the liver tissue. Hence, we conclude that the egg white phantom will prove usefulin quantitatively evaluating the thermal effects of therapeutic ultrasound.
