Distributed System Software Via NSFNET for Global PACS

这一为期三年的项目旨在满足开发 PictureTM的体系结构和分布式系统软件 和通信系统（PACS）和全球PACS。 PACs 环境是一个更大类别的图像的子类 数据库系统，分布在一个地方和国家 地理区域。 PACS的研究始于早期， 20世纪80年代，目前正在开发用于医学成像 医院环境。 在PACS中，患者信息和 每当病人经历一次 在医学成像设备上的过程，例如X射线， 计算机断层扫描（CTSCAN）和磁共振成像（MRI） 机械. 信息和图像通过 高速网络连接到数据库存档系统，其中的数据 后来被放射科医生的高分辨率工作站 进行诊断。 在全局PACS中，数据可以通过 并在PACS和国家档案馆之间进行检索 中心. 在本研究项目中， 全国各地的各种医院承担，该项目是 将互联方法发展到NSFNET和 分布式系统软件，以实现全球PACS原型 环境问题 *

This three-year project addresses the need to develop the architectures and distributed system software in Picture Archiving and Communications Systems (PACS) and Global PACS. PACS environments are a sub-class of a much larger class of image database systems, distributed over a local and national geographical area. PACS have been researched since the early 1980's and are currently being developed for use in medical imaging and hospital environments. In a PACS, the patient information and digital images are generated every time a patient experiences a procedure on a medical imaging equipment, such as an x-ray, computed tomography (CTSCAN), and magnetic resonance imaging (MRI) machines. The information and images are transferred through a high speed network to a database archive system, where the data are later retrieved into the radiologist's high resolution workstation for diagnosis. In a Global PACS, the data may be transferred and retrieved across country between PACS and national archive centers. In this research project, the existence of local PACS in various hospitals around the country is assumed, and the project is developing the interconnection methods into the NSFNET and the distributed system software to implement a prototype Global PACS environment.***
