RAY TRACE MODELING OF MULTIPATH IN ULTRASOUND POWER MEASUREMENT SYSTEM

摘要

The measurement of ultrasonic power in liquids (commonly water) is based on the measurement of the radiation force using a gravimetric balance. A schematic representation of the INMS ultrasound power measurement system is shown in Fig. 1. A conical target submerged in water is suspended using thin wires from a small hook at the bottom of an electronic balance. The transducer with its active surface submerged in water is positioned coaxially above the target. The radiation force generated by the transducer that impinges on the target is measured by the electronic balance [1],
