  1. because from slsicer I have to export in nrrd format and then get the stl format when slicer latest version exports directly to stl ??
    maybe the tutorial for medical exams is dated ??

  2. Successfully printed.

    we are using Raise3d 2n plus and IdeaMaker slicer. The slicer is free and an outstanding slicer.

  3. How to section a skull in half

    Here is a message I recently received. I am posting my reply in hopes it will help others. ------------------------------------------- QUESTION: My name is ___________ and I am a student at the University of Missouri, attempting to print 3D images from CT scans. I have found your video extremely helpful and had a question if you don't mind about blender. My question is that lets say I want just the left half of the skull. How can I cut the skull down the middle, select the right side and delete. I have tried to find Blender YouTube tutorials about this but none of them have been helpful. It would be great if I could get your opinion on the matter. Would that be possible? Thank you so much for your time! Truly enjoyed the tutorial a lot! -------------------------------------------- ANSWER: The best way is to subtract the side you don't want by using a boolean operator. Start by creating basic shape, such as a cube, and scale it up so that it is bigger than the skull. Then, position the cube over the portion of the skull you want deleted. Then, with the skull selected, select the boolean modifier, choose difference, and the target should be the cube. Everthing that intersects with the cube should be gone. Be sure to accept the changes the modifier made. Good luck!

    Agree. 284 models to choose from as of today!

  6. Betty's CT Scan by Gary Rodgers

    Think so. Sounds like your wife had a percutaneous ablation of a renal tumor? There will probably be a large ablation defect on the latest scan. A good 3D model might show this well. Good luck!
  7. You know that there are hundreds of CT scan files available on this website, right? Take a look at this link and start exploring. https://www.embodi3d.com/files/category/37-medical-ct-scan-files/
  8. 3D print fetus from ultrasound images

    I too, would like to know how to do this. Hopefully someone will share their method!

    Crop it and you will drastically reduce the size. Sometimes even cropping out the air around the body can reduce the size by 50% without losing any structure. Here is a tutorial that shows you how to use the Crop Volume function in Slicer. Good luck.

    Thanks for the reference. Can you elaborate on the IP theft you mentioned? What happened?

  12. Knee MRI Models

    I was recently asked the following question by a member, and I thought I would share the answer so others in the community could benefit. --------------------- Dear Dr. Mike, My thesis focuses on knee biomechanics and I was hoping I could pick your brain in this regard. I have to obtain MRI scans of a knee which will be later segmented and the model will be eventually used for finite element analysis. Since I have very limited knowledge in this, I was wondering what parameters (such as sequence, weighting, resolution, slice thickness) should be maintained during an MR procedure so as to obtain the best contrast between various soft tissues which will make the segmentation easier? Thanks for your help! ----------------------- I recently completed an MRI knee segmentation (image below). The best way to do this is to use a high resolution (sub 1mm slice thickness) T1 or proton density series of the knee. If you want to exclude the fat, you can do a fat-saturation sequence, but my understanding is that it is hard to get thin slices with fat-sat sequences. I used Slicer's segmentation module to segment the individual structures. If you want to put the entire knee back together, you can add the structures together after they are all segmented. Hope this helps! Dr. Mike
  13. Valve Geometry

    Valves are tough. You would have to get a high resolution EKG-gated coronary CTA most probably. EKG-gating is necessary to avoid blurring of the values. I don't know of any datasets off-hand. Anyone in the community know of any?
