Embodiment Construction
[0032] The present invention relates to a kind of method that uses 3D printing model to carry out the method for in vitro fenestration of aortic stent, which comprises the following process steps:
[0033] 1) CT or MRI scan of the patient's aorta to obtain image data and form a DICOM file;
[0034] 2), identify the DICOM file in step 1), extract different data templates, and modify them to make the template clearer and more complete;
[0035] 3), intercept the image in step 2), remove unnecessary parts, keep only the opening of the aortic branch, and delete the part far from the opening;
[0036] 4), process the 3D image formed in step 3) to form an STL file;
[0037] 5), import the data processed in step 4) into the 3D printer, and print out the lesion model; the material of the model is opaque, translucent or transparent, hard or soft; the model is sterilized after completion deal with;
[0038] 6), select the appropriate type of aortic stent-type blood vessel, and releas...
