I am working with micro-CT scans of mosquito larvae (~3.97 µm voxel size) and I am trying to generate rendered anatomical visualizations similar to the figures in this paper:
I hope to create reconstruction of the whole exterior of the body and the interor organs. I currently have reconstructed BMP slice stacks and have imported them into 3D Slicer, and I am importing them with the help of Imagestack. However, I am struggling with the reconstruction/rendering workflow and understanding the best pipeline for reconstructions.
I was wondering what is the recommended workflow in Slicer/SlicerMorph for micro-CT datasets like insect larvae which is mainly soft tissue( i have used iodine staining to before microCT scanning)? I have aldready masked only the tissues and got rid of the background! I was wondering what I should try using primarily like Volume Rendering, Segment Editor, Surface meshes, Slice rendering or a combination? I am worried that it might be too hard to manually segment all the tissue types because of how small the images are.
One place to start is to see if you can get the images in the highest resolution possible from the scanner. BMP files are typically 8-bit grayscale, which is typically less than the scanner would produce natively. So definitely check that before you do anything else. And as a general rule, the better the scan the better the visualizations, so be sure you have optimized your acquisition.
Beyond that, you can do all the things you mentioned in Slicer, and probably more. There are lots of tutorials, and probably the SlicerMorph ones are closest to your needs.
If you want to share you images people might be able to give more specific guidance.
Thank you for the replty, we played with the resolution, and this was the highest we were able to get. Addionally I am either only using the last 500 sections and importing it with full resolution or all the sections with Half resolution as I am trying to figure out a wokflowpipeline, especially because my computer is also not able to handle the whole dataset on slicer! Also I was wondering what would you reccomend changing to the transfer function to see iodine stained tissue more clearly. Since there is only a subtle contrast between the different types of tissue, what direction should i try focusing on!
I would also recommend to use segmentation to assign different colors to different anatomical regions, using Colorize Volume module (provided by Sandbox extension).
These figures are actually very simple to reproduce, but there is a trick to it. Make sure the slice views are turned on in the 3D view, and the slice being shown and the crop positions are identical. here is an example. I specifically set the volume rendering color a little different so that it is clear what the 2D slice view is adding. Default cropped internal rendering:
