On the Application of Acoustic Pressure Weighting for Controlling of Acoustic Focusing by Planar Phased Array
摘要
Abstract
An approximate weighting formula of acoustic pressure with method of compen-sation to the amplitude and phase of the controlled acoustic pressure is given in this paper. A synthesis pattern based on the pseudo-inverse matrix algorithm can be obtained by pre-setting the value of the controlled acoustic pressure. A planar phased array comprised of 10 × 10 square elements is used for numerical simulation. The results show that the sound energy can be effectively deposited at the desired points. This study may offer an effective way for controlling the distribution of acoustic field in ultrasound hyperthermia.关键词
