High Intensity Focused Ultrasound (HIFU) is identified as the truly non-invasive modality enabling tumor heating and ablation in treatment of breast tumor, uterine fibroid, bone tumor, prostate carcinoma, hepatic carcinoma, pancreatic neoplasm, and so on. However, as the conventional transducers are fixed on the probe relatively without position changes, there is a severely limit for the movable range of the focus. This article mainly introduced a real time multi-angle adjustable Phased High Intensity Focused Ultrasound (PHIFU) system, which could implement focusing at different positions by adjusting the angles between disparate transducers in real time under the driving of digital servos. The angle detectors are installed between two digital servos to acquire the precise angles in order to feed back to the system. In return, the angles could be also calculated if the position of the focus was given. This way improved the scope of the focused ultrasound therapy greatly from the results of the acoustic field simulations.
