一种用于医学图像分析的网格信息基础设施
A Grid Information Infrastructure for Medical Image Analysis
摘要：
数字图像的存储和操作以及对这些图像中所包含的信息的分析是下一代医疗信息系统的基本要求。医学界一直在探索用于管理图像数据和交换知识的协作方法，网格技术[1]是一种很有前途的方法，可以实现跨医疗机构的分布式分析，并开发新的协作和合作方法进行图像分析，而无需临床医生共处一地。欧盟资助的MammoGrid项目[2]就是一个例子，它旨在开发一个欧洲范围的乳房X线照片数据库，以支持欧盟医疗保健专业人员之间的有效合作。MammoGrid原型包括一个高质量的临床医生可视化工作站（用于数据采集和检查），一个DICOM兼容的接口，用于连接一组驻留在所谓的网格盒上的医疗服务（注释、安全、图像分析、数据存储和查询服务），并安全访问通过网格中间件连接的其他网格盒网络。该项目的主要交付成果之一是一个支持网格的基础设施，用于管理整个欧洲的联合乳房X光检查数据库。本文概述了MammoGrid信息基础设施（MII）的元数据分析和知识发现在医学成像领域。
英文摘要：
The storage and manipulation of digital images and the analysis of the information held in those images are essential requirements for next-generation medical information systems. The medical community has been exploring collaborative approaches for managing image data and exchanging knowledge and Grid technology [1] is a promising approach to enabling distributed analysis across medical institutions and for developing new collaborative and cooperative approaches for image analysis without the necessity for clinicians to co-locate. The EU-funded MammoGrid project [2] is one example of this and it aims to develop a Europe-wide database of mammograms to support effective co-working between healthcare professionals across the EU. The MammoGrid prototype comprises a high-quality clinician visualization workstation (for data acquisition and inspection), a DICOM-compliant interface to a set of medical services (annotation, security, image analysis, data storage and querying services) residing on a so-called Grid-box and secure access to a network of other Grid-boxes connected through Grid middleware. One of the main deliverables of the project is a Grid-enabled infrastructure that manages federated mammogram databases across Europe. This paper outlines the MammoGrid Information Infrastructure (MII) for meta-data analysis and knowledge discovery in the medical imaging domain.
