Four learning tools of the Visible Korean contributing to virtual anatomy

The sectioned images of a male’s whole body were used for making the four learning tools: the first tool to show the sectioned and color-filled images; the second tool to show surface models of individual structures; the third tool to show a volume model that was continuously peeled; the fourth tool to show a volume model that was freely sectioned. This study was intended to propose the possible learning effects of the four tools. The fourth tool that was recently developed to facilitate oblique sectioning and rotation of the volume model in real time. The four learning tools had their own characteristics, so that they could be separately used for specific achievements. Further, the combination of the tools based on the same raw data may result in a synergic effect. All the tools can be downloaded from the Visible Korean homepage (anatomy.co.kr) gratis. With the four learning tools, students may experience virtual dissection simulation regardless of the place, time, or economic status. Such free learning tools and commercial learning tools need to be improved to compensate and compete with each other.
