The present invention relates to a method and a system for extracting a 3D region of interest from a stack of medical scan slices which is still a challenging task even in this new millennium. One difficulty is that there is no robust automatic algorithm that can handle all the different situations and applications. Human intervention is usually unavoidable for extracting desired area or organs. However, without convenient tools, it is a tedious job for human being to go through hundred or thousand of slices just to extract region of interest. A system combines and modifies several advanced techniques to help a user extract volume of interest very easily and quickly. The technique of livewire for initial-delineate and modify regions of interest from 2D slices is utilized. Then variational interpolation technique is employed to derive a 3D shape from these delineated 2D contours. The 3D shape can be visualized as is or converted to a 3D solid for volume visualization or masking out of the undesirable parts of a data set.
