A Custom-Built Piezo-Optical System for Visualization and Characterization of High Intensity Focused Ultrasound
High intensity focused ultrasound (HIFU) is a noninvasive treatment technique to induce thermal or mechanical bioeffects.Characterising the wave field is essential for reliable and reproducible transducer operation in clinical use.This paper presents a schlieren technique to visualise and quantify transducer wave fields.The technique is based on th
