Abstract
We investigated possibilities of application of boundary element method (BEM) to modelling of acoustic fields generated during ultrasonic angioplasty. It was shown that modelling by means of BEM can be more efficient comparing with traditionally used modelling by means of finite element method (FEM). We also considered test problem of calculation of acoustic field created by ultrasonic waveguide in semi-infinite fluid media and the problem was solved by means of BEM and FEM with comparative analysis of obtained results. Modelling by means of BEM additionally involves application of mirror source method for avoidance of treatment of infinite fluid boundary. On the basis of analysis of the test problem we shown that BEM can be used as efficient tool for modelling of acoustic fields generated during ultrasonic surgical procedures, particularly, during ultrasonic angioplasty. BEM has several advantages in comparison with FEM and can be used as alternative to traditionally used modelling by means of FEM or as supplementary method.
