| 中文摘要: |
| 本文通过数值计算及实际测量，研究了凹球面声透镜聚焦换能器及凹球面自聚焦换能器产生的声场，证实此两种聚焦方式均可获得理想的聚焦效果，但自聚焦方式更适合高强度聚焦超声（HIFU）加热治疗。 |
| 英文摘要: |
| Sound fields generated by transducers with concave spherical acoustic lens and by transducers with concave spherical piezo-electric ceramic are studied through numerical calculations and experiments in this paper. The results indicate: focusing effect can be obtained in either case, but the latter transducer is more adaptable for high intensity focused ultrasound(HIFU) therapy. |
