摘要
介绍了一套用于便携式小型伽玛相机成像的高性能数据采集系统。为满足其便携式移动方便的要求,该数据采集系统的设计基于通用的USB接口,采用模块化的设计与系统集成。选用多通道数据同时采集的高速USB-ADC卡(DT9836)与LabVIEW软件开发平台,实现了高分辨小型伽玛相机多通道数据的同时采集、处理、图像显示与存储等功能。测试结果表明,该数据采集系统的采集速率可达200 K/s左右,能很好满足该便携式高分辨伽玛相机系统的成像要求。
In this paper, a high-performance data acquisition system is designed for a portable compact gamma camera. Based on a generic USB interface with modular design and system integration, it uses high-speed USB-ADC （DT9836） with NI LabVIEW sottware development platform to achieve simultaneous multi-channel data collection, processing, image display and record for the high-resolution gamma camera. Test results show that this data acquisition system can achieve a sampling rate of up to 200 K/s, well meeting the requirements of a high-resolution portable gamma camera.
