多参数可调低强度脉冲超声治疗系统的研制

Design of multi-parameter adjustable low intensity pulsed ultrasound therapy system

针对目前市场上的低强度超声治疗设备功能单一,参数固定,不能满足实验研究和临床治疗中需要的多功能参数的问题,研制了便携式、模块化、低成本、多参数宽范围可调的低强度脉冲超声治疗系统,其中可调参数包括:频率、占空比、脉冲重复频率、编码类型和输出功率等。本设计包括系统硬件与软件设计,并对该系统进行了多种测试,包括:阻抗分析、声场测试、声功率测试和系统效率测试等。测试结果显示,该系统具有较好的灵活性和稳定性,能满足多场合的应用需要,具有广阔的应用前景。

The current commercialized low intensity ultrasound therapy system has single functionality and fixed parameters,therefore it can hardly satisfy the multi-functional requirements of experimental and clinical applications. This study developes a portable,modular,low-cost low intensity pulsed ultrasound therapy system,with adjustable wide range of multi-parameters,such as frequency,duty cycle,pulse repetition frequency,type of encoding,output power,etc. This design included hardware,software and system tests such as impedance analysis,acoustic field measurement, acoustic power measurement and system efficiency test.The results show that the device has good flexibility and stability,which meets the needs of many applications and has broad prospects.
