Perceptive Factors for Volume Visualization in Medical Image Analysis

In the context of medical image analysis, it is useful to study how effectively the renditions created through volume rendering depicts anatomical structures and how well features of anatomical structures can be discerned in order to make decisions. In this paper, we firstly analyze the roles of perception for volume visualization in order to get perceptual factors which affect the effectiveness of volume visualization. The perceptual analysis results are then used to design visualization tools to demonstrate their effects on visual perception and mental models. In this paper, we mainly focus on depicting two kinds of object structural relationships that are important for extracting and understanding structures of interest: topological relationships (e.g. inside/outside) and spatial positional relationships.
