外文翻译--一个可用于PET和SPECT镜像的高速率的USB数据采集系统的应用
1、 1 中文中文 3155 字字 出处：出处： Nuclear Science Symposium Conference Record, 2006. IEEE. IEEE, 2006, 5: 3063-3067 Implementation of a High-Rate USB Data Acquisition System for PET and SPECT Imaging Abstract We made substantial progress with a flexible high-rate USB data acquisition system developed for gamma
2、-ray imaging detectors. Hardware consists of 16-channel data acquisition modules installed on USB carrier boards. One， two， and four-module units were developed. USB data rate was increased to over 30 MB/s and a 16-channel configuration achieved a trigger rate of over 700 kHz. Several high-resolutio
3、n single-gamma detectors and two high-rate PET detectors were instrumented. The detectors use various configurations of Hamamatsu H8500， H9500， and Burle 85002-800 PSPMTs. System channels were expanded by synchronizing additional acquisition units. A Java client-server system was developed to link a
4、cquisition computers over Gigabit Ethernet. A Kmax tool was developed to process and display images during acquisition. C and Java utilities were developed to assist development and diagnostics. I. INTRODUCTION A new high-speed USB-based data acquisition system was previously developed to instrument the gamma-ray imaging detectors designed by the Jefferson Lab Detector and Imaging Group 1. It was successfully demonstrated on a variety of detectors and configurations. Scalability from 16 to 128
