| Research Abstract |
Ultrasound techniques have been playing important roles both in diagnosis and therapy. As a basic technology to support development of these applications, improvements are also required for evaluation techniques of ultrasound fields. In this study, an ultrasound field visualization system using image subtraction Schlieren technique was designed and fabricated with corroboration of an experienced manufacture. The developed system was used for visualization of ultrasound fields generated by clinically used diagnostic and therapeutic ultrasound equipment. Short-pulsed ultrasound fields for diagnostic applications and continuous-wave high-intensity focused ultrasound fields for therapeutic applications were successfully visualized, indicating practical usefulness of our technique as basic technology to support further progress of ultrasound applications in medicine.
