Dear MITK users, we would like to announce a major change for the manual segmentation:
Since today 3D interpolation is activated by default when using the manual segmentation tools. That means if you start contouring, from the second contour onwards, the surface of the segmented area will be interpolated based on the given contour information. The interpolation works with all available manual tools. Please note that this is currently a pure mathematical interpolation, i.e. image intensity information is not taken into account. With each further contour the interpolation result will be improved, but the more contours you provide the longer the recalculation will take. To achieve an optimal interpolation result and in this way a most accurate segmentation you should try to describe the surface with sparse contours by segmenting in arbitrary oriented planes. The 3D interpolation is not meant to be used for parallel slice-wise segmentation. Similar to the former 2D inter-slices interpolation you can accept the interpolation result by clicking the "Accept" - button below the tool buttons. In this case the 3D interpolation will be deactivated automatically so that the result can be postprocessed without any interpolation running in background. We tried to keep the interpolation as fast as possible. During recalculation the interpolated surface is blinking yellow/white. When the interpolation has finished the surface is shown yellow with a small opacity. Additional to the surface, black contours are shown in the 3D render window. They mark the positions of all the drawn contours which were used for the interpolation. You can navigate between the drawn contours by clicking on the „Position“ - Nodes in the datamanager which are located below the selected segmentation. If you don't want to see these nodes just uncheck the „Show Position Nodes“ Checkbox. If you want to delete a drawn contour we recommend to use the Erase-Tool since Redo/Undo is not yet working for 3D interpolation. If you don't want to use this new feature you can easily deactivate the interpolation with the radiobuttons below the manual tools or you can again use the 2D interpolation. If you encounter any problems, please don't hesitate to contact us! Regards Andreas Fetzer Dipl.-Inform. Med. Andreas Fetzer Deutsches Krebsforschungszentrum (German Cancer Research Center) Div.
