While medical images are fundamental in the surgery planning procedure, the process of analysis of such images slice-by-slice is still tedious and inefficient. In this work we introduce a system for exploration of the internal anatomy structures directly on the surface of the real body using a mobile display device as a window to the interior of the patient’s body. The method is based on volume visualization of standard computed tomography datasets and augmented reality for interactive visualization of the generated volume. It supports our liver surgery planner method in the analysis of the segmented liver and in the color classification of the vessels. We present a set of experiments showing the system’s ability to operate on mobile devices. Quantitative performance results are detailed, and applications in teaching anatomy and doctor-patient communication are discussed
