The white color indicates that it is very dense. In the CT scan image shown in Figure 1, the hard, dense cortical bone is seen as a bright white outer surface of these pelvic bones. Take this CT scan of the pelvis, for example. On a CT scan you can see these two different types of bone. The inner core of most bones contains fatty bone marrow, and is made of much softer bone that is less dense, called spongy bone. This tough outer part of the bone is very hard and is what gives bones their strength. Most bones have a very hard, very dense outer layer comprised of cortical bone. Bones are not solid, even though they may appear to be so. You can watch the YouTube video for a high-yield introduction, but also read this page for additional details.īefore we dive in, let’s take a moment to discuss what the medullary cavity of a bone is and why it’s a problem if you’re trying to 3D print bone models made from a CT scan. If you would like to follow along with this tutorial, you can download the relevant Blender and STL files here, and follow along. Here we will use a free, open-source software package Blender to repair and correct a bony pelvis and lumbar spine model generated from a CT scan. If you do not yet know how to do this, stay tuned, as a series of tutorials is planned on this website. This is an advanced tutorial and assumes that you already know how to create STL files from CT scans. Cleaning and repairing STL file mesh from bones using Blender, an advanced tutorial.
