    • 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
