We propose an automated needle hydrophone based scanning system to obtain high-resolution planar acoustic pressure distribution generated by high intensity focused ultrasound (HIFU). The preoperative scanning plan manipulates the position of HIFU transducer and automates the acquisition of spatial acoustic pressure distribution. In particular, a method to minimize the displacement error induced by the time delay improves the scanning speed problem of the conventional needle hydrophone based scan system. Moreover, the noise-robust and automatic focus searching algorithm using Gaussian curve fitting reduces a total number of iterations as well as prevents divergence of searching the initial scanning position.
