High intensity focused ultrasound, HIFU has been used to non-invasively treat human tumors, such as uterine fibroids, prostate cancer, breast cancer, liver tumor, and brain tumor. However, the tumor in some organs can be moved by human breathing and heart beat, which may cause the ablation and damage of normal tissues during the sonication of HIFU. The purpose of this study was to develop a HIFU phased...
A two-element sensor array was modeled. Preliminary results showed a significant difference of transmission coefficient level with the presence of the tumor and the decreasing level of the transmission coefficients when tumor shifts off the center. Moreover, an investigation carried out to study the effect of skin layer shows the skin layer reduces the coupling between two sensors and it is feasible...
