Labeled three-dimensional multi-modal brain structure fusion reconstruction method for brain tumor

The invention discloses a tagged three-dimensional multi-modal brain structure fusion reconstruction method for brain tumors. The method comprises the following steps: acquiring a brain CT image, a brain MRI image, a brain artery blood vessel image, a brain vein blood vessel image, a diffusion tensor image and a brain perfusion image; taking the T1 thin-layer scanning image as a reference, respectively registering the brain CT image, the enhanced image, the cerebral artery blood vessel image, the cerebral vein blood vessel image, the diffusion tensor image and the brain perfusion image, and fusing all the registered images to obtain a brain structure 3D image; and separating a brain tumor structure from the enhanced image layer in the brain structure 3D image to obtain a multi-mode brain structure 3D image with a brain tumor. According to the method, fusion reconstruction is carried out through the multi-modal image, the multi-modal brain structure 3D image with brain function partitions can be generated, the
