The research on digitized human brain atlas is an important part of brain research at present. In early times, the printed brain atlas played an important role in neural anatomy research, teaching and daily applications, but the form is single, and content is fixed, the 2D images make it difficult for doctor to establish the 3D images of brain structures, not suitable for digital processing and storage, the registration of atlas and patients’actual data is seriously restricted. Digitized human brain atlas compensate for the shortcomings of the above.This paper introduces the design and implementation of an digitized brain atlas software. The software is applicable to students, teachers and researchers, it is an interactive tool, mainly used in the neural anatomy teaching.With the basic idea of software engineering, we analyze the need of customer and design the overall structure of the software, and divide the software into two-dimensional module, three-dimensional module and related auxiliary module. Then the source of Talairach slice, MR slice in two-dimensional module as well as the three-dimensional model data in three-dimensional module are analyzed, the data preprocess is also researched. There are two models in the 2D module, explore-model and test-model. The explore-model has six functions: image mark, distance measure, set 3D plane, search and clear. It enables the customer to do interactive operations to the 2D images. The test-model has two functions:“where?”and“what?”. It enables the customer to test their study results. The 3D module is based on OpenGL, it enables the customer to see three-dimensional images of the brain structures, enhance the understanding of brain structures mutual location. We focus on the research of the tree hierarchy of brain structures’labels and the object picking method.The software is developed in Visual C++ integrated develop environment, through some tests, it is proved that the software can help a lot in the neural anatomy teaching, and has some help in neural scientific research as well.
