In the past years sophisticated automatic segmentation algorithms for various medical image segmentation problems have been developed. However, there are always cases where automatic algorithms fail to provide an acceptable segmentation. In these cases the user needs efficient segmentation editing tools, a problem which has not received much attention in research. We give a comprehensive overview on segmentation editing for 3D medical images. For segmentation editing in 2D, we discuss a sketch-based approach where the user modifies the segmentation in the contour domain. Based on this 2D interface, we present an image-based as well as an image-independent method for intuitive and efficient segmentation editing in 3D in the context of tumour segmentation in CT.
