Ultrasonic wave focusing process for e.g. medical application, involves fixing transducers on reverberating solid object that provokes multiple reflections of ultrasonic excitation wave

摘要

The process involves transmitting an ultrasonic excitation wave having a mid-band transmission frequency (fc) and focused in a target point of a target medium (2) e.g. patients body. Transducers are fixed on a reverberating solid object (7) that provokes multiple reflections of the wave. A pulse wave of duration 1 divided by fc entering the object leads to an acoustic transmission of duration 10 divided by fc towards the medium. - An INDEPENDENT CLAIM is included for a device for focusing ultrasonic waves.
