Detailed description of the invention
A kind of method of the 3D printer model with coordinate, for organ surface or inner anatomical site while 3D prints, two planes of decussation are set up by human body horizontal position transverse section, sagittal plane direction, joint is the specific region of anatomy, tumor, blood vessel and two vertical intersection coordinate planes is printed so simultaneously.By the initial data of medical image (CT or MRI), by special 3D modeling software, such as 3DSlicer, interprets blueprints and sets up 3D data, finally the 3D data generated is printed by " 3D printer "; When setting up 3D data, CT or the MRI plane as anatomical site is selected to carry out the foundation of 3D coordinate plane.Select the specific region of anatomy, manual drawing grid on transverse section, cylindrical wire (conventional 3D modeling software can complete), the grid netting twine of netting twine selection diameter 3mm are spaced apart 1cm; With the right hand edge sagittal plane at critical anatomical position, manual drawing grid, the cylindrical wire (conventional 3D modeling software can complete) of diameter 3mm selected by netting twine, grid netting twine is spaced apart 1cm.While the coordinate grid setting up 3 dimensions, according to the special 3D modeling software of initial data of adopted medical image (CT or MRI), the organ printed needing 3D or tumor, blood vessel delineate out, carry out the foundation of 3D data.So establish the 3D data of organ or tumor, blood vessel simultaneously, and 3D coordinate data.By 3D data input 3D printer, carry out the printing of 3D model.
embodiment 1
As Figure 1-5, the 3D as liver neoplasm and blood vessel prints, and porta hepatis can be selected to be anatomical site, and set up coordinate and print, tumor and the blood vessel 3D printer model of this band coordinate can help doctor to make the selection of operation plan.
Example is established as: the initial data (.dicom file) Hepatic CT scanned with the 3D printer model of liver neoplasm blood vessel, import medical image 3D professional software, such as 3DSlicer, selects portal vein to enter the position (porta hepatis) of liver as anatomical site.Find corresponding transverse section plane, with the portal vein rightmost side in plane for initial point, set up horizontal, vertical coordinate, set up corresponding graticule according to transverse and longitudinal coordinate, set up grid, adjacent graticule interval 1cm.Find corresponding sagittal plane plane, with the portal vein rightmost side in plane for initial point, set up horizontal, vertical coordinate, set up corresponding graticule according to transverse and longitudinal coordinate, set up grid, adjacent graticule interval 1cm.While the coordinate grid setting up 3 dimensions, according to the special 3D modeling software of initial data of adopted medical image (CT or MRI), the organ printed needing 3D or tumor, blood vessel delineate out, carry out the foundation of 3D data.So establish the 3D data of organ or tumor, blood vessel simultaneously, and 3D coordinate data (.bim file).3D data (.bim file) are inputted 3D printer, carries out the printing of 3D model.
