Parameter forms to customize algorithm
behaviour
T2 and T2* parametric map generation
algorithm (liver iron overload measurements)
developed by University of Crete and
integrated into Research PACS
Convert independent images or image
series to 2D and 3D matrices and send
them directly to Matlab
Import 2D and 3D matrices from Matlab
to independent images and image
series to become part of the
examination
Import Matlab Figures as images

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
