Abstract

The invention discloses a method for constructing a three-dimensional brain model, comprising the steps of using a magnetic resonance skull sagittal thin layer to image; obtaining data with a T1DICOM format as a source material; transforming the source material into an image with a bmp format; separating a target image from the image with the bmp format; introducing the obtained target image to a three-dimensional reconstruction software; setting space position in an empty manner, producing a mask and constructing a crude three-dimensional model; converting the crude three-dimensional model into a low surface target model by means of surface lowering processing; finally, connecting the low surface target model and the original data with the T1DICOM format to obtain the three-dimensional brain model. When the three-dimensional brain model constructed by the invention and the original skull magnetic resonance target picture are verified, the contour line of the three-dimensional brain model is nicely consistent with the edge of the original image with the T1DICOM format.

Description

technical field [0001] The invention relates to a method for constructing a 3D digital brain model, in particular to a method for three-dimensionally recombining tomographic images to form a three-dimensional brain model. Background technique [0002] Neuroanatomy is a medical morphological science with a wide range of content and complex spatial structure, especially the abstract and incomprehensible anatomy of the skull base and brain is a prominent problem and difficulty in teaching and clinical practice. The traditional method is to use chalk, blackboard, textbooks, Two-dimensional means such as wall charts and projections are used to explain, and then the specimens are taught to train doctors. Clinically, the cerebral cortex and deep brain structures are the basic parts of neurosurgery work, but the spatial structure of the cerebral cortex and its deep nuclei is very complex, and it is difficult to clearly and accurately grasp it. Therefore, neurosurgeons often borrow t...
