CT or MRI to
3D-print
Dicom to STL
Background
With the data from a CT or MRI-scan it is interesting to examine it in a 3D software and finally make a 3D-printout. Great to have when planning or making an fixtur before an operation.
After a CT-scan I asked for the data and received a DVD with the scanned data as DICOM files. These are just flat 2D "X-ray" images.
Workflows
Two different (free) workflows, 1 Cloud or 2 Local computer calculations on Mac or PC
I have built on this very good tutorial: 3D Printing in Medicine by Dr. Mike
And of course there are several other different workflows for making a 3D-print out of CT or MRI dicom files then this!
So Links and resources is last on this page. There you can find some more alternative workflows :)
1. Cloud
Much easier, less fiddling with the segmentation
Faster to result when inexperienced
Dicom (CT, MRI-2D files) -> NRRD-file (anonymized ) -> Cloud computing (Embodi3D) -> Mesh (STL 3D-model) -> repair, adjust -> make a 3D-print
Step by step guide here
2 Local computer
Full control of the files and
more possibilities when doing the segmentation
Dicom (CT, MRI-2D files) -> Mesh (STL 3D-model) -> repair, adjust -> make a 3D-print
Step by step guide here
If Workflow 1 or 2 above is not enough then just dig deeper with these external resources! See below.
