CT image segmentation eTELEMED 2015Piotr Bała 10

Segmentation process  CT image set (DICOM-Dir) is used as starting point  CT data is selected  Affine registration  Free Form Deformation parametrized by B-splines.  The resulting deformation field is segmented  Volumetric tuning of every segment boundary using patients original data. segmentation proces depends on the image library eTELEMED 2015Piotr Bała 11

Conclusions  Grid technology became mature enough to offer reliable, high quality services designed to suit requirements of different scientific communities.  UNICORE Portal offers web interface and automation of the processing of selected applications  The medical doctors can focus on diagnosis instead of writing complicated scripts, transferring the files and mastering complicated IT infrastructure.  With the UNICORE Portal creation of the application and domain specific solution become simple and straightforward.  The software stack necessary to build full featured gateway is now small and easy to handle. eTELEMED 2015Piotr Bała 18
