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。 Introduced a set of high-performance data acquisition systems for portable, compact gamma camera imaging. In order to meet the requirements of portable convenience, the data acquisition system is designed based on the universal USB interface and adopts the modular design and system integration. High-speed USB-ADC card (DT9836) and LabVIEW software development platform are also used to capture and process multi-channel data of high resolution and small gamma camera at the same time. The test results show that the acquisition rate of the data acquisition system can reach about 200 K / s, which can well meet the imaging requirements of the portable high-resolution gamma camera system.
