Abstract
The invention is disclosed to design a real-time pulse/echo system to perform 1-D real-time temperature measurement and integrate in the high-intensity focused ultrasound system. In the invention, a modified echo-time shifting algorithm is developed to calculate the corresponding phase shift from echo signal, which correlates with the instantaneous temperature change during heating process.
