In this work; we present a haptic-enabled application for interactive editing in medical image segmentation. We use a fast surface rendering algorithm to display the different segmented objects; and we apply a proxy-based volume haptics algorithm to be able to touch and edit these objects at interactive rates. As an application example; we show how the system can be used to initialize a fast marching segmentation algorithm for extracting the liver in magnetic resonance (MR) images and then edit the result if it is incorrect.
