Ultrasound CT Water coupled

The article presents a performance analysis of fully automated, in-house developed 2D ultrasound computerized tomography systems using different programming languages. The system is fully automated in four programming languages:  LabVIEW, MATLAB, C and Python. It includes codes for sensors, instruments interfacing, real-time control, synchronized data acquisition, simultaneous raw data processing and analysis. A microcontroller integrated, multi-actuator based electro-mechanical assembly designed to provide complete scanning in three dimensions. It employs a parallel beam geometry to scan the specimen and perform the reconstruction based on the transmission data. The automatically controlled mechanical assembly of the scanner is integrated with its synchronized data acquisition, complex signal processing and inverse problem based image reconstruction software.

本文针对自研全自动化二维超声计算机断层扫描（Ultrasound Computed Tomography）系统，开展了基于不同编程语言的性能分析研究。该系统分别采用LabVIEW、MATLAB、C与Python四种编程语言实现全自动化运行，其代码涵盖传感器适配、仪器接口开发、实时控制、同步数据采集、同步原始数据处理与分析等功能模块。系统搭载集成微控制器（Microcontroller）、多执行器驱动的机电组件，可实现完整的三维扫描。该系统采用平行束几何方案对扫描样本进行扫描，并基于透射数据完成图像重建。扫描仪的自动控制机电组件，与同步数据采集、复杂信号处理及基于逆问题的图像重建软件实现了集成。
