Interactive contouring is a commonly-used tool for interactive segmentation and modification of contours of tumors and organs on medical images. The teaching points of this exhibit are: 1. Computer-aided contouring (CAC) provides an accurate, reproducible, and efficient toolkits for interactive contouring of tumors and organs. 2. CAC assisted with novel interactive hardware provides a quick tool for contour tracking and reviewing. 3. CAC reduces the inter- and intra-observers viabilities of interactive contouring.  

1. Explain the emerging role of computer-aided contouring (CAC) for accurate and reproducible interactive segmentation of tumors and organs. 2. Technical explanation of CAC: illustrate the theory of optimal-path searching on 2D transversal images with minimal user-identified control points. 3. Experiments of CAC: demonstrate the improvement of accuracy, reproducibility, and efficiency of CAC in the segmentation of liver and liver tumors on CT images using interactive pen and digital drawing tablet. 4. Discussion of the effectiveness and limitations of CAC techniques in quantification of tumor and organs in clinical applications.
