    Cervical spine .stl file from CT scan

    This is a .stl file produced from a CT scan of myself.
    I used 'InVesalius 3.0 free' to convert the 2D dicom images into the .stl file.
    I use either 3D Tool or Materialise's MiniMagics (free versions) to view and manipulate the 3D image.
    I have been told I had a severe hyperflexion injury to my c spine during an assault in 1988 and sustained a number of fractures and subluxations which were not diagnosed by a hospital as they discharged me from the ER in error before I had been examined by a Dr. It wasn't until I had a CT scan in 2011 and produced 3D images from it that I discovered various bony abnormalities that were subsequently identified as fractures & subluxations by experts. I understand the right transverse process of T1, tip of C6 spinous process and the left greater cornu of the hyoid bone are the most obvious old fractures that can be seen.

    3D Printer Ready Human Hyoid Bone

    Methods
    3D Medical imaging data was obtained in the .stl format. The hyoid bone was localized from the .stl --sectioned off in the software -- and that part of the anatomy was revised using 3D modeling techniques to be highly adaptable to 3D printing platforms for potential regenerative medicine applications.
    Author and Licensing
    This hyoid bone re-topology was performed by Chris Leggett. It is free to use for research purposes, with modifications as needed, and any future clinical purposes with standard citation practices for using this material and under the creative commons attribution license.

    Vertebral column (Dorsal, Lumbar & Sacral spine) - STL file from converted CT scan

    The dorsal (thoracic) spine forms the middle portion of the vertebral column extending below the seventh cervical vertebra to above the first lumbar vertebra. The dorsal spine is formed by twelve vertebral bodies.
    The vertebrae forming the dorsal spine are unique in shape as they are the only vertebral bodies articulating with ribs.
     
    The lumbar spine represents the mid-lower segment of the vertebral column and is composed of five adjacent vertebrae. They are convex anteriorly to form a lumbar lordosis. The lumbar spine facet joints allows limited movements and rotation.
     
    The sacrum is the lower most segment of the vertebral column and also forms the posterior wall of the bony pelvis. The sacrum is formed by five fused sacral vertebrae.
     
    This model shows the origin of ribs, few of the cervical spines and the sacroiliac joint. The minimal tilt seen is likely positional rather that pathological.
     
    This 3D model was created from the file STS_036. The source CT scan used to create this model can be found here.

    Pelvic Bones 3D Printable STL File Converted From CT Scan

    The bony pelvis is formed by 4 bones; a pair of hip bones, the sacrum and the coccyx. The bony pelvis supports the pelvic viscera and works to transmit force from the axial skeleton to the lower limbs.   The two hip bones are related anteriorly at the symphysis pubis and posteriorly to the sacroiliac joint bilaterally. This particular 3D model shows some irregular material floating within the pelvic cavity which represents a contrast media in the colon, that contrast media is given for patients prior to CT scans to distinguish intestinal loops.   This 3D model was created from the file STS_044. This file was created from this CT scan.

    Pubic Symphyses: Male, 18yo

    These are the pubic bones of an 18yo male (ABD_LYMPH_010) from the CT Lymph Nodes Collection of TCIA, which is made available under Creative Commons Attribution 3.0 Unported License.
     
    I modeled these with the Grayscale Model Maker in 3D Slicer (see tutorial pt. 1), hollowed with Meshlab, fixed for printing with Meshmixer.
     

    "ABD010_PS_M18_1mm.stl" has a wall thickness of 1mm to minimize material volume for printing through Shapeways--I would recommend white "strong and flexible plastic."
     
    "ABD010_PS_M18_closed.stl" is hollow with filled holes--this is what I would use for filament printers, but you could use this to print a solid model through Shapeways.
     
    I haven't printed this model yet, but I will post pics when I do!

    Pubic Symphyses, Male 60yo

    These are the pubic bones of a 60yo male (ABD_LYMPH_004) from the CT Lymph Nodes Collection of TCIA, which is made available under Creative Commons Attribution 3.0 Unported License.
     
    I modeled these with the Grayscale Model Maker in 3D Slicer (see tutorial pt. 1), hollowed with Meshlab, fixed for printing with Meshmixer.

    "ABD004_PS_M60_LR_1mm_cut.stl" has a wall thickness of 1 mm to minimize material volume for printing with powder-based printers (for example, through Shapeways)--I would recommend white "strong and flexible plastic."
     
    "ABD_004_PS_M60_flat2.stl" is hollow with filled holes--this is what I would use for filament printers, but you could use this to print a solid model through Shapeways.
     
    I also cut the bottoms flat on both so they can be oriented upright to print--I would not recommend printing with the symphyseal face up because the layering process will impose ridges.
     
    I've included a screenshot showing how to split the left and right halves in Meshlab using the filter "Split in Connected Components"--once split, each "layer" can be exported as separate .stl files. The "Plane Cut" tool in Meshmixer can be used to further cut the models if you want smaller segments.
     
    If you would like to add shading to the 3D models to enhance viewing of the symphyseal face, in Meshlab apply the Filter--> Color Creation and Processing--> Ambient Occlusion per Vertex.

    • 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
