Sistema sanitario nazionale ha come scopo primario la salvaguardia della salute della persona Persona = Tessera Sanitaria Paziente = Cartella clinica Gli elementi costitutivi della cartella clinica sono indicati nel Dm della Sanità 27 Giugno 1986 che prevedendo "per ogni ricoverato, la compilazione della cartella clinica, da cui risultino le generalità, la diagnosi di entrata, l'anamnesi, gli esami di laboratorio e specialistici (immagini TAC, MR…..), la diagnosi, la terapia, gli esiti e i postumi".

PACS. Picture archiving and communication system PACS ! Picture archiving and communication system ( Sistema di archiviazione e trasmissione di immagini ). Le immagini sono memorizzate in un archivio on-line (server dedicato) molto veloce, poi trasferite in un archivio intermedio per un periodo di un anno ed, infine, memorizzate in archivi più economici di lungo termine.

How to use GRID Storage System Application Server hosts the application and the underlying interface. The interface works as a Front End for the Grid Data Services. Grid Data Management System

GRID Storage Access Framework or GSAF Interface GSAF interface is a wrapper of the main Grid Data Services and provides a unique, simple and useful API (Application Program-ming Interface ) for building multi-purpose applications based on the Grid Storage (e.g. medical, archive,banking …). The most important requirement of GSAF interface is to hide the complexity and the fragmentation of the several APIs ( one for each storage services), provided by the Grid Middleware in order to supply only one programming interface.

GSAF High Level Architecture

Behavior description VOMS Client - allows interactions with the Grid Security Infrastructure File Manager – permits operations with files (store/retrieve) Catalogue Manager – provides functions about file trace keeping Metadata manager – supplies functions to manage descriptive attributes for files

GSAF interface satisfies Healthcare Application Requirements Organize file collections within the repository Store file to remote storage Associate descriptive metadata with files Search and identify files using keywords (search engine) Browsing file collections Retrieve desired files (displaying or downloading them) All these functionalities are provided to application ensuring coordination and coherence among different transactions.

New Web Applications on GRID Healthcare Storage The end

New Web applications on GRID Healthcare Storage The idea is to build a web application on top GSAF as a prototype of medical application based on a Grid Storage. Users will be able to manage files (patient records, medical images, …) and their own metadata remotely towards a web user interface. Repositories can be organized according Sanitary Organizations needs, mapping each of them on different Grid Virtual Organizations. For each organization appropriate access control rules and / or sharing policies can be defined. Medics according to both the access rules of the organization they belong to and inter-organizzation sharing rules, can arrange their own archives, define metadata (also standard compliant) for different types of file collections (records, images, …) and manage them (upload, download, google flavour search, browsing and download).
