Posterior Superficial Cervical Muscles
At the Barrow Neurological Institute, my project goals was to replicate a patient's CT data and the tumors within. This was done with the purpose to later be used in mixed reality in the combination of a VR headset and 3D printed model to teach medical residents different surgical techniques while minimizing risk and stress.
Substance Painter
Once I was done sculpting as shown, I decimated the mesh to bring the object into Substance Painter. In Substance Painter I baked the high poly UV Map mesh to the low poly object to minimize data. This allowed me to paint on a mesh that maintained the original details of the 3D object without slowing down Substance Painter, or Unity's user experience in the future.
ZBrush
In ZBrush I sculpted the muscles a lot to achieve the correct look from the original mass that I started with. I began by blocking out the correct shapes, leveling out the thickness of the muscles in comparison to each other, and then added the striations for necessary directional affect.
3D Slicer
To view the desired back muscles in 3D Slicer I created a new segment layer and thresholded out the tissue density only. The green highlight is the tissues that were gathered outside the already segmented anatomy. I then narrowed the island "size" allowance to get a more detailed sculpt of the muscle forms. Creating segmentations is creating separate 3D models that can be brought into ZBrush and further manipulated.
