Interactive Multi-Organ Segmentation based on Multiple Template Deformation

International audience<p>We present a new method for the segmentation of multipleorgans (2D or 3D) which enables user inputs for smart contour editing.By extending the work of [1] with user-provided hard constraints thatcan be optimized globally or locally, we propose an efficient and user-friendly solution that ensures consistent feedback to the user interactions.We demonstrate the potential of our approach through a user studywith 10 medical imaging experts, aiming at the correction of 4 organsegmentations in 10 CT volumes.We provide quantitative and qualitativeanalysis of the users' feedback.
