Summary:An ultrasonic tissue mimicking phantom is a useful tool for the performance testing and calibration of ultrasonic medical devices. However, it is hard to estimate the thermal distribution caused by the ultrasound in the human body using a conventional phantom. In this study, a tissue mimicking phantom to visualize the thermal distribution was developed by using thermochromic particles. The acoustic characteristics of the phantom were investigated according to the ingredient ratio of the phantom. Changing the ingredient ratio, the acoustic characteristics of the phantom can be adjusted to those of human tissue.
