| 中文摘要: |
| 经声振后的造影剂能提高声学成象的清晰度,有可能提高超声临床诊断的质量。用实验室现有的超声设备制剂时其操作要十分小心且声强低而时间长,为克服这些缺点,研制了一台换能器工作在并联谐振点的高声强发生器。文中叙述了电路的主要设计方法。初步实验的结果表明,效果良好,能满足实验室造影剂声振的要求。 |
| 英文摘要: |
| Ultrasound contrast agent can improve distinctness of the formation of acoustic imaging,and it is possible to improve the quality of ultrasonic clinical diagnosis.It needs carefulness to make ultrasound contrast agent using existing ultrasound devices in lab,and the produced sound intensity is low,and it takes more time.To overcome these shortcomings,a generator with high intensity of sound was developed that works on the point of parallel connection resonance.This paper describes the main way of designing circuit. The results of experiment evince that the generator has good effects and can meet the demand of sound vibration of ultrasound contrast agents in lab. |
