Objective To construct a visualization platform of digital human brain. Methods With the use of the cross - section slice images of human brain selected from the Chinese Visible Human Dataset

Visual C++ and VTK software were adopted to develop the framework of visualization platform and implement the visualization of human brain in Windows operating system

involving 3 - D reconstruction based on Marching Cube algorithm and the interactive virtual cutting of the model based on 3 - D widget

etc

. Results The visualization platform of digital human brain was successfully established

which provided a variety of functions including the multi - value surface reconstruction and volume reconstruction

the accurately interactive 3 - D clipping

dynamic observation of virtual slice image in an arbitrary orientation

dynamic setting of rendering parameters and rotation of 3 - D model. Conclusion The platform demonstrates the anatomic features of human brain elaborately

and therefore provides a powerful tool to facilitate a series of clinical applications

such as anatomy teaching and planning of brain surgery.
