Objective  To establish a digital segmentational data set of larynx based on Chinese visible human (CVH).   Methods  Magnetic lasso and polygon tools of Photoshop were used to segment the small organs and structures of larynx of CVH to establish the segmentational data set of larynx. After conversion of the image format

the segmentational structures were extracted automatically with Thresholding Method and presented 3-D visualized

and then were checked up by its result of 3D reconstruction with Amira 4.1 software.   Results  Many small structures of larynx were segmentated

such as laryngeal cartilage

laryngeal muscles

vocal cords and so on. Then the segmentational data set of larynx based on CVH was established

which can be used to 3-D reconstruction accurately.   Conclusion  The segmentational data set of larynx is accurate and integrated

which is helpful to establish the elaborate model of larynx and can provide the method of color image segmentation.
