                         situations such as surgical planning and training. Currently, it 
                         becomes possible with the augmented reality, a technology which 
                         enables the visualization of the patients virtual anatomy at the 
                         location of the real one in a conventional display. In this work, 
                         we present a markerless augmented reality environment for 
                         on-patient medical data visualization, which supports: 
                         photorealism, advanced methods for real and virtual data 
                         composition and additional features such as occlusion. From an 
                         evaluation of the proposed environment, the results obtained 
                         highlight that it runs in real-time and provides good visual 
                         quality for the augmented scene.",
