• Medical Library Prototype
• THE MAIN GOALS
• POLITICAL (popularization of GRID and
  NorduGrid).
• To demonstrate to the ordinary people (medical
  specialists, students etc....) the new working
  information technology invented as by-product of
  High-Energy Physics.
• PRACTICAL to create this medical library
  prototype to be really useful for the didactic
  purposes of teaching medical students.
• TECHNICAL to test the existing NorduGrid and
  GRID technologies for this specific application.

Medical Library Prototype

• Distributed storage system for large amount of
  medical images
• Authorized remote access
• Catalogization of metadata associated with
  images
• Searching of images through metadata
• Open source software

Medical Grids

• Medical GRIDS short overviewhttp//www.nicpb.ee/

• Examples of Grids for digital mammography
• - e-Diamond (Software IBM's DB2 and
  DiscoveryLink middleware)
• - GPCALMA(AliEn),
• - MammoGrid(AliEn),

Commercial Picture Archiving and Communications
Systems (PACS), Examples

• M.D. Anderson Cancer Center's (USA) physicians
  are viewing over 200,000 diagnostic-quality
  images per month (!)
• Xancers Xtria 3 Million Multi-year contract
  with Illinois-based Michael Reese Hospitl

7
Our goals

• To create the Didactic Medical Images Library
  prototype (for medical students, etc)
• To use existing NodruGrid middleware
• To use the DICOM standard of medical images
• To apply existing DICOM viewing software

8
Realization

• We want to use
• SSE as storage system
• RLS as metadata catalog
• Globus authorization system
• Nordugrid client software

Nordugrid allows to realize the following scheme
(inserting image and metadata)
Lfn, metadate

Conclusions

• We continue the development of the Distributed
  library archive prototype based on Nordugrid RLS
  and SSE services
• Distributed DICOM storing services are realized
• RLS server for storing of metadata
• Two SSEs
• We are finishing alpha version of the interface
  module
• The results can be used as a base for future GRID
  applications for medical DICOM images archives
  (Computer Aided Diagnostics, batch image
  processing etc..)
