Objective: To improve the image quality of the specimen serial sections for establishing the Virtual Chinese Human dataset and to extend the durability of the milling tools.
Method: The image quality of the serial sections obtained by using tangential and radial indexable milling tools was compared.
Results and conclusion: Compared with radial milling tools, tangential ones were more suitable for use in this study to ensure high-quality section image acquisition, showing the advantages such as high efficiency, long durability and low cost.
