INTRODUCTIONWeb Tele-Medicine Platform

The concept of Teleradiology
What is teleradiology? “A teleradiology system acquires radiographic images
at one location and transmits them to one or more remote sites, where they are displayed and/or converted to hard copy.”
Batnitzky, S., et al., Teleradiology: an assessment1990
Introduction
The basic paradigm hasn’t change
5
The concept of Teleradiology
What has changed then? Technology Security measures (HIPAA) DICOM (Digital Imaging and Communication on
Medicine)
Introduction
Basic common (today’s) Teleradiology System
6
The concept of Teleradiology
Data exchanged: Usually is inject in the system from inside the
hospital/clinic Requested by external means (telephone, mail, e-mail) Stored on a Database outside the hospital/clinic
Nowadays we can do better…

PROBLEMS THAT DIFFICULT
TELERADIOLOGY SOLUTIONS

Security and ConfidentialityProblems that difficult Teleradiology solutions
If the paradigm hasn’t change we still have to face the same principals: Hospitals/clinics maintain secured networks Information is sent through the Internet Information must always be secured Information is usually stored on a external environment
Single point of attack can result in mass illegal retrieve of data
What can we do then?
9
Security and ConfidentialityProblems that difficult Teleradiology solutions
Store securely the data to be displayed
Images need to be sent through secure channels
Firewalls protecting Hospital’s networks
Physician needs to be authenticated
Trust the agent that sends data to the outside

PROPOSED SYSTEM’S ARCHITECTURE
Web Tele-Medicine Platform
11
Proposed System’s ArchitectureWeb Tele-Medicine Platform
Implementation of a automated PACS broker:DICOM Gateway
Non DICOM normalized Queries
Physician authenticated using Single Sign-on principle
12
Proposed System’s ArchitectureWeb Tele-Medicine Platform
Authentication: All the components that are in the flow of data must be
authenticated before any data is exchanged Gateways Physicians
Single Sign-On principle
Confidentiality: Assured by exchanging tokens before any sensitive
data is really needed The flow of data is done in secured connections
HTTPS
13
Proposed System’s ArchitectureWeb Tele-Medicine Platform
PACS Virtualization Through web page
Different uses for the same system: Sharing cases and remote access PACS Sharing cases anonymously
By using image temporary tokens

FUTURE WORKWeb Tele-Medicine Platform

Future WorkWeb Tele-Medicine Platform
Future work: Implement the DICOM Gateways Implement a web page Implement authentication mechanisms…
To sum up, code the studied theory and architecture
