Description:GRID Archive for DICOM image
Abstract:<b>Experiment</b>Nowadays, hospitals and medical structures produce a big amount of DICOM images for several kind of clinical exams (such as TAC, MR, PET, SPET, x-ray), and they usual store them into specific servers called PACS (Picture Archive and Communication System). However, these PACS are inflexible and they don\’t allow to manage in an efficient and secure way the great mass of data stored in their memory. Typically, portions of digital objects are moved on DVD support or other massive memory devices and not used anymore. This big and so important health care patrimony is than practically lost.
<b>Application</b>: GRIDICOM project aims at the realization of a Digital Archive for DICOM images that uses the Grid infrastructure as a Digital Repository. The main idea is to gather all images generated by PACS distributed in several geographic locations, extract all their fully qualifying metadata (DICOM), make them anonymous and organize them inside a big Grid archive. GRIDICOM architecture counts two main components: a Software Interface able to interact to the Grid Data Management Service in order to exploit all repository capabilities; and a client/server application made by agents working remotely at PACS side and a centralized collector that works as Storage Manager at Grid side. In this context: automated management tools make the archive able to be managed with less administrative time; fast access to historical images helps contribute to improve patient care; redundant architecture helps to ensure image accessibility even in the event of the loss of data centre. Moreover, repositories can be organized according Sanitary Organizations needs, mapping each of them on different Grid Virtual Organizations, and for each organization appropriate access control rules and/or shared policies can be defined. Finally, the knowledge base is enriched towards a simple and powerful Web Interface to allow Human users to access, browse, search and provision the whole archive according to the Grid Security mod
