Case Study


Since our first presentations in EuroPACS 2006 the Research PACS system evolved:

Redesigned image viewing to support multiple views and independent image processing modules that the user can easily arrange on screen

Minimized lossless image retrieval time even through the Internet using advanced streaming technology

Improved networking capabilities including server to server synchronization

Optimized for large data sets (multi-slice studies) and large number of examinations

Tested the system as a regular RIS-PACS in two University Hospitals in Greece

Advanced image viewing and processing (includes 3D reconstruction)

Full two-way integration with Matlab

End-users can develop their own image processing techniques in Java or Matlab within the system. All RIS-PACS information and functionality is available to these techniques

Exports ROI statistics from multiple exams/images to Excel

Some Screenshots

T2 and T2* parametric map generation algorithm developed by University of Crete and integrated into Research PACS

The screenshot demonstrates an application to liver iron overload measurements

Integrated electronic medical record that can retrieve information from any HIS through HL7

Workflow- and role-based exam life-cycle support

Extended statistics on productivity

Easily and fully localizable to any language


Some Screenshots

Advanced series synchronization and 3D reconstruction are part of the basic functionality. Everything is available to new image processing techniques developed by end-users

Multi-view image presentation that can be arranged easily by the user

Two-way integration with Matlab


Researchers can develop and test new image processing techniques at a fraction of time required before

The incorporation of generated images, measurements and other information in publications has been significantly accelerated

New techniques are validated faster to become immediately available for application by radiologists on regular examinations

Geographically dispersed team members reduced travelling, minimized image exchange and increased their productivity
