    The cervical spine is the upper most spines forming the spinal column, extending from the skull base to the level of the thoracic vertebra (the spines with attached ribs). The cervical spines are usually seven and the main function is to support the skull and to protect the spinal cord. Apart from the first cervical vertebra (atlas) and the second vertebra (axis), the other vertebral bodies share a general anatomical appearance: Oval shaped vertebral bodies with wide vertebral arch, large vertebral foramina and long spinous processes. This particular model shows parts of the mandible as well as the hyoid bone. This 3D model was created from the file STS_044. The source scan used to create this file can be found here.

    I am not sure if dealing with solidify modifier is safe procedure. I tried a lot, every time something was wrong. I mean complex geometries of lumen with irregular narrowing from thrombus or atherosclerosis. Every time I lost the ideal lumen of the vessel. Some solution to it, is shrink-wrap modifier, but to be honest it has big limitation like you mention before. I don't think that it would handle with dissections either. So for that moment, I think we don't have perfect solution to mirror the ideal anatomy of vessel lumen. We can be close, but not accurate. Maybe Dr. Mike has different opinion? The second aspect is segmentation. What program you recommend ? Osiris or slicer? I think that when we use the threshold for Hounsfield units for contrast medium , we also segment part of calcium atherosclerosis which has very big Hounsfield value. Around plaque segmentation see a transition zone which corresponds the value of Hounsfield for contrast medium which we see as very irregular surface. Of course we do smoothing as post processing in blender, however its not dealing perfectly with it. Even if it does, we lose ideal shape of lumen. So same again, we are close but not accurate. If anybody knows how to deal with these problem, please share with me.

    I don't fill those surfaces, I use solidify modifier so there is no need to merge two edges after offset. And, maybe it is confusing, but even when you do solidify or whatever, you will still have "hidden space" between two surfaces (inner/outer shell...). When printing, 3D printer doesn't recognise that space as empty yet it is prints it as solid, full...

    I closed the cut edges of outer and inner surface with extrude and scale but still is a hidden space between these to layers. I think this is the reason why i Have problem with proper use of boolean modifier to later add the supports to the model. So what are yours method of filling these two surface?

    My Mandible This is a model i used to test my ability to get a 3d printed model out of a CT (conebeam). Segmented on itk-snap.

    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. 0522c90878
