Contour interpolation in medical imaging

Planning of medical procedures, such as radiation therapy or minimally invasive interventions, almost always require delineation of organs and other important structures by closed curves. Most frequently this is performed manually, by drawing contours around the objects on several two-dimensional cross-sectional images.

Typically the contours change smoothly between adjacent image slices, therefore it could be possible to speed up the contouring process by drawing contours manually only on a limited subset of images and generating contours between the manually contoursed slices by interpolation.

The contour interpolation method could be also used for generating visually appealing and accurate surface models from sparse manually defined contour sets.
