Terms and Concepts What do we Mean Here by “eHealth” and “HealthGrid”? Demo Session - Biomed - CDSS
Terms and Concepts: eHealth • eHealth Deals with Using Information and Communication Technologies to Develop an Intelligent Environment that • Enables Ubiquitous Management of Citizens’ Health Status, • Assists Health Professionals in Coping with some Major Challenges, • or Integrates the Advances in Health Knowledge into Clinical Practice. • Health Term is Considered in a Broad Sense. Demo Session - Biomed - CDSS
Terms and Concepts: HealthGrid • HealthGrids are Grid Services or Middleware Components that Deal with the Specific Problems that Medical Data Processing Involve. • Resources in HealthGrids are Databases, Computing Power, Medical Expertise and Even Medical Devices. • Health Grids Aim at Assisting Epidemiology and Individualised Healthcare: • Integrating Large Databases and Extracting Knowledge. • Execute Complex Simulations on Biomedical Models. • Process Large Genomic Databases. • Securely Exchange Medical Data and Share Applications for its Processing.

What do Physicians Need? Problems and Needs in eHealth Demo Session - Biomed - CDSS
Problems and Needs in eHealth • Ubiquitous, Quick and Secure Transference of Information. • Medical Information is: • Large, Increasing in Size and Relevant on the Long-term. • Medical Data is Critically Confidential. • Legal Regulations at National Level Difficult the Integration of Large Repositories of Personal Data. • Consolidated Access • Interconnection of the Different Isles of Information (HIS, RIS, LIS, PACS, Primary Care IS, …). • Solve Incompatibilities on Data Format. • Data are Heterogeneous in Format and Nature. • Potentially Incomparable (Acquisition, Post-processing). Demo Session - Biomed - CDSS
Problems and Needs in eHealth • Large Computing Power is Needed • Medical Information is Huge. • Information Processing Requires Large Computing Resources. • Pervasive Access and Fault Tolerance • Medical Healthcare is Performed All Over the Clock, 7 Days a Week. • Fault Tolerance to All Other Critical Resources (Water, Light, Heating) is Considered. • New Applications • Computer-Aided Diagnosis. • Patient-Customized Therapy. • Large-scale Knowledge Discovery. • Large Scale Post-Genomics and Proteomics.

The Grid as an Enabling Technology What are the Strengths of Health Grids? Demo Session - Biomed - CDSS
The Grid as an Enabling Technology • Driving Factors • Structure • Networks of Centres Cooperating in one Aim. • Staff Sharing Experiences and Even Exchanging Personnel. • Distributed Architecture of Grid Fits Healthcare Provision Structure. • The Concept of Virtual Organisation is Crucial in Grid and perfectly matches the Structure of Healthcare Users. • Infrastructure • High-Bandwidth Networks are Available Among Public and Private Healthcare Centres. • Open-minded • Used to Research and Advanced IT. • Concern on Patient’s Satisfaction. Demo Session - Biomed - CDSS
The Grid as an Enabling Technology • Driving Factors • Technological • Security is a Basic Technology on the Concept of Grid. • Interoperability and Resource Sharing are the main Aims of the Grid Concept. • Filters can be Executed Locally to Transform Data into an Homogeneous Format. • Local Administration is Preserved in the Grid. • Low Requirements on the User Side is Also Adequate. • Robustness with Data and Service Replication. • Economy • Service-Oriented Business is Optimal for Healthcare. • Better Use of Resources and Scalable Costs. • Free Maintenance Tasks.

HealthGrid Activities-TUV Activities of the Techn. Univ. of Valencia (TUV) in the HealthGrid Area Demo Session - Biomed - CDSS
Data Grids • Storage and Processing of Medical Images on the Grid. • Virtualization of a Distributed Storage for Medical Images. • Integration of Components that Post-Processes (Rendering, Segmentation, Co-Registration) • Semantic Integration of Radiological Reports. • Searching and Progressive Transmission of Data. • Following Current Standards (DICOM, OGSA, WSRF). Demo Session - Biomed - CDSS
Peer-to-Peer Environments • A Peer-to-Peer Environment to Share Medical Images and Diagnostic Reports Providing Content-Based Searching. • The Objective is to Ease the Collection of Cases, Especially Those Regarding Infrequent Diseases or to Reach a Sufficiently Large Sample for Epidemiological Studies. • Although the Studies are Available on the Different Medical Centres, There are no Means to Access and Share The Information. • The Tools Enables Sharing Individual Studies, Joining the Own Resources of Each User. • It Implements Authentication, Automatic Anonimization, Distributed Searching, Progressive Transmission and User and Diagnoses Ranking. Demo Session - Biomed - CDSS
High Performance Post Processing • Rendering of Very Large Medical Images with Corporate Grids • Visible Human Project Dataset (1500 Slices). • The Volumetric Projection has a Large Requirement of CPU, but Also of Local Memory. • Grid Technology Enables Sharing the Resources (Memory and Processing Power) of the Computers Connected to a Network. • Co-Registration of Medical Images in the Grid • Distributed Storage of Abdominal MRI Volumes and Co-Registration using Deformable Methods. • Oriented to the Study of Pharmacokinetics. • Basic Grid Gain Per Study of Above 12, But Raising above 80 if Enough Resources.
