High intensity focused ultrasound (HIFU) is a new noninvasive method for treating certain tumors. Tissue mimicking phantoms are used to test HIFUs because it provides real time visualization of HIFU induced lesion evolution, and can calibrate the HIFU transducers. This study investigates the thermophsyical properties of egg white phantoms at room temperature, and varying concentrations of egg white. Measurements of thermal conductivity, diffusivity, and specific heat were taken using a ...
