(30 Dec 2008 14:18 GMT) - In recent years HIFU has been widely used for the treatment of solid tumours, such as liver tumour, bone tumour, and breast cancer. The mechanism for therapeutic actions of HIFU includes thermal effects and non-thermal effects with the latter dominated by cavitational effects. Adjusting acoustic parameters of pulsed high intensity focused ultrasound (PHIFU) can control thermal effects and non-thermal effects; short duty cycle and high intensity favours the occurrence of cavitation…
