Abstract [en]

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.
