Embodiment Construction
[0034] Below in conjunction with embodiment the invention is described in further detail:
[0035] The invention relates to a method for preparing a composite model of brain tissue and blood vessels based on MRI and CTA. The present invention uses nuclear magnetic resonance and Philips 256-slice ultra-fast CT to scan the head, obtains cranial MRI and CTA image data, imports the obtained MRI and CTA image data into Mimics software respectively, and reconstructs the skull, brain tissue, blood vessels and The three-dimensional composite virtual model of the aneurysm is imported into a 3D printer for printing, and the preparation of a three-dimensional solid model including brain tissue, blood vessels and aneurysm is realized.
[0036] The embodiment of the present invention takes an aneurysm patient as an example to describe in detail: through Mimics 18.0 3D reconstruction software 3D composite virtual model, input 3D printing to obtain a 3D composite solid model including skull,...
