Abstract

A design of high-precision angular position control system for calibrating high intensity focused ultrasound (HIFU) is presented with alignment procedures. Two independent angular controls are achieved by combining a worm gear and a belt gear system. The proposed system verifies alignment by comparing simulation data and experimental data with three different transducers and two different types of hydrophones. The performance of the proposed system is compared to that of a commercial system. The results indicate that the proposed system provides high precision angular alignment (e.g., <0.01radians) with robust reproducibility regardless of the hydrophone type.
