Image dicomimport

The DICOM importer is a simple wizard that allow the user to import images directly from a DICOM exam. It can reconstruct 3D volumes from 2D DICOM files.

IMPORTANT : This tool does not import 3D DICOM files ! You can open them directly from the open button.

First click on the ``Open'' button to choose the DICOM root directory that contains the exam. Carefull : the importer will scan recursively into this directory, don't choose a directory that contain several exams to prevent from memory overloads.

The volumes should now appear in the main table window. Each line with an arrow represents a volume. Double click on it to see what files this volume is made from. Clicking on one file will popup the corresponding image on the view window in the upper right corner. The files should be shown in correct order, following a consistent strategy : files are first splited in series and ordered by the image position DICOM flag. If for some reason the user ends up with a mixed up volume, it might be because of image position conflicts (It often happen in T2/proton density protocols). Then the user can click on ``split'' button that provides a consistent split process among the image positions given in the DICOM files. Clicking on reset button will go back to the original configuration.

Last step (click ``finish'') will reconstruct 3D volumes from the last given fileset configuration.

IMPORTANT : The DICOM importer in its current state doesn't take care of the orientation acquisiton of the the image. That might results in ``radiologic convention'' issues.

All the DICOM exam volumes are now visible in the preview window. For the user convinience, a ``save all'' button has been added in order to quickly save all the loaded images in a given directory. They will be saved in ITK Analyze format (.hdr - .img).
