In medical image analysis and surgical planning, it is an essential task to visualize and differentiate multiple anatomical structures. The traditional approaches require expensive 3D segmentation steps during pre-processing stage, which defeats the purpose of real-time interaction with the data. In this paper, we propose an interactive method for visualization of multiple anatomical structures. In our results, we show that the new method is a promising technique for visual analysis of medical datasets and a helpful tool for surgical planning. It can be very efficient for a wide range of visualization and analysis tasks.
