基于智能移动设备的A超眼球生物测量系统

摘要

Ocular biometry has a great clinical significance, an A-scan ocular biometry system based on smart mobile devices is designed in this paper to make the measurement moreconvenient and economical. A data collection module is used to emit ultrasonic waves and receive the echoes. After being converted to digital, the echo signals are sent to the smart mobile device by bluetooth,the mobile device is used to display the waveforms,process the echo signals,provide control interface and remote communicate. The phantom and in vivo experiments show that the system is able to achieve accurate and reliable measurements. Since echo data display and processing is independent of data collection in the system, ophthalmologists can use their own smart mobile device to reduce greatly the cost of ocular biometry.%眼球生物测量具有重要的临床意义,为了提高眼球生物测量设备的便携性与经济性,文中提出一种基于智能移动设备的A超眼球生物测量系统.该系统由数据采集模块和智能移动设备构成,两者通过蓝牙接口进行信息交互,数据采集模块用于发射超声和接收回波,智能移动设备用于显示和处理回波数据、 整机控制及远程通信.体模实验和在体实验均表明,文中系统测量结果准确可靠,稳定性好.如果医师利用自带的智能移动设备,可以大大降低眼球生物测量的成本值得在临床推广.
