    Craniofacial Model, Female 57yo

    Skull and face models were generated in Mimics from a CT scan from TCIA (citations: http://doi.org/10.7937/K9/TCIA.2015.K0F5CGLI, https://doi.org/10.7717/peerj.2057, https://link.springer.com/article/10.1007%2Fs10278-013-9622-7) as reference models for visualizing skin-to-bone relationships for forensic craniofacial identification applications. See Figshare for additional project information.
     
    Face model was hollowed in Meshlab and extruded to this individual's minimum facial tissue depth (1.6 mm) with Meshmixer (tutorial). Cuts were made in 3D Slicer using the EasyClip plugin to cut at specific landmark coordinate values: skin was cut through x-coordinate of pronasale and right oculus anterius, z-coordinate of bony glabella; bone was cut through x-coordinates of left and right oculus anterius, z-coordinate of glabella, y-plane was adjusted until posterior to cheilion.
     
    For 3D printing, I rotated the model until the posterior surface was flat on the bed and added a raft to hold the supports (I left the raft on--see pic), but a custom platform could be added instead with Meshmixer or Tinkercad. I usually leave most of the supports attached to hold the skin layer in place, but remove supports from inside the nasal aperture and sometimes remove supports from the lateral side to reveal the infraorbital foramen. I don't have dual extrusion, but you could probably print the skin in one color and bone in another. The above pics show a print at 300 micron resolution.
     
    **Note that this file contains two merged models that can be printed together or separately--to separate, open in Meshlab, right-click the model name in the layer dialog and select "Split into Connected Components" and save each layer as a separate model.

    Skull base and jaw with dental artifact

    This CT scan of the jaw, face and cervical spine show the effect that metal dental fillings can have on a 3D printed part. Other than the artifact from dental fillings, the quality of the model is excellent.

    • Hi Mike - starting with Cone beam CT files.  Will play with Hounsfield settings next time.  For this particular case I learned enough on Slicer and Meshmixer to get the job done. 
    • You are diving into the deep topic of medical imaging scans for 3D printing. I wrote a blog article on how to get the most out of your scan here. Take a look as it is very helpful.   3mm is not bad for a CT scan for 3D printing.  In order to understand why the radiology department created 3 mm slices, you need to understand how CT scans work. Modern CT scanners do not acquire data in slices. Rather, the acquisition is helical. The patient moves in the scanner on the Z axis at a fixed speed, while the x-ray tube spins around that axis during acquisition. As a result, relative to the body, the x-ray tube moves around like a helix, i.e. corkscrew. The raw data from this acquisition is stored in memory in the CT scanner. It is then reconstructed into flat slices that can be of any thickness anywhere from 0.5 mm to 5 mm.   Thinner slices are not always better however. There is a fixed number of x-ray photons that were acquired during the scan. When the slices are created after the fact, the data that those photons created is spread among the slices. If you have a lot of very thin slices then there are few photons per slice. Just like with a handheld camera when you shoot in low light, having a low number of photons results in a grainy image. The exact same things happen with a CT scanner. Thin slices tend to be very grainy and it can be difficult to detect abnormalities when the image quality is poor. Thicker slices on the other hand are fewer in number and have more photons per slice and thus are less grainy. Think of a nice photograph from a handheld camera on a bright sunny day. There are so many photons to make the image, the image is crystal clear. Thicker slices, while giving a higher quality image, are also thicker, and very small structures are harder to see.   Therefore, if you had a CT scan and reconstructed 0.5 mm slices, those images would be much grainier and of lower quality than if you had reconstructed with 5 mm slices. When the scan is being taken the radiologist determines what slice thickness is the best for diagnosing the problem at hand. If you're getting a CT scan of the abdomen for appendicitis, you will get 5 mm slices. If you have a problem with your middle tier and are getting a CT scan of the mastoid, you'll probably get 0.5 mm slices.   It should be noted that the raw data from the scan acquisition takes up a lot of memory. While the reconstructed slices are saved in the hospitals radiology system, the raw data from the scan is stored on the physical scanner itself. Typically after a few days that data is purged to make room for new scan data. So, after a few days it is not possible to generate any new slices from the scan, as the raw data has been purged.   My guess is that 3 mm slices is as good as you are ever going to be able to get from your scan. To reduce the stairstep artifact, run a smoothing algorithm on your model. This should reduce that appearance.   I hope this helps   Dr. Mike    
    • 1) Nothing in this forum should be considered medical advice. 2) The scan shows some extent of pectus excavatum. Heart is a bit displaced as a result. 3)  Evaluation of the heart itself is poor because the scan was not protocoled to examine the heart (i.e. no ECG gating). My guess is they were looking for PE, and there is no obvious one.   Good luck
    • If you increase the threshold value (150->250 Hounsfield units), that will tend to include less bone in the model. If decrease it, more bone will be included.    Just want to check -- are you starting with a CT or an MRI. CTs work better.   Hope this helps.   Dr. Mike
    • I use 3D slicer and the segmentation module. It takes a little time to get familiar with the tools, but they can be pretty powerful.   I just did this kidney yesterday, including the kidney tissue, renal collecting system, artery and vein.    FYI, we are building the ability to automatically segment organs into democratiz3D. Right now it only supports creation of bone models, but in the future auto segmentation of organs will be a feature.    Hope this helps,   Dr. Mike
