Hit the “Filters” -> “Smoothing” -> “Laplacian Smooth”.Ī window will come up and change the Smoothing steps down to one. The next step will smooth everything out so it will look nicer. Sometimes you may have to do this a few times before the numbers in the pin boxes in the corner all read zero.Ħ. Then do the same thing, but instead of selecting the non manifold edges use the “Select non manifold vertices” and delete those as well. Next go to “Filters” -> “Selection” -> “Select non manifold edges” and then delete them like you did when you were using the selection tool (“Filters” -> “Selection” -> “delete selected vertices”). This will bring up a box that should look like the following:ĥ. Once you have the parts that you want to print isolated, go to “Render”-> ”Show non manif edges” and again to “Render” -> “Show non manif vertices”. Again, this takes a while, so take your time.Ĥ. This is the most time consuming part of the process because if you want a nice print you need to make sure to remove everything you don’t want in the print. Once you have a selection made you will go to the “Filters” -> “Selection”-> “Delete Selected vertices” and this will delete whatever you have selected. When you select something it will select everything that falls within that box regardless if it is behind something else.ģ. IMPORTANT: make sure that the selection you make is not overlapping any piece that you want to keep. To do this you will use the “select verteces” tool in the upper right part of the tool bar. For this demo I only want the first two vertebrae of the neck which are known as the Axis and the Atlas. Once the file is loaded we need to trim down the file to include only the parts we want. *Be sure to save your project often–Meshlab seems to crash a lot.Ģ. You should have something that looks similar to this (with your own image): Select the file that you just exported from OsiriX and press okay when the window pops up. Once you have downloaded Meshlab and installed it, open it up and select “File” then “Import Mesh”.
Osirix dicom to stl software#
The next program we are going to use is a free software called Meshlab.ġ. (*Be sure to keep track where you are saving everything because we are using several programs and lots of steps.) Find the small gear in the corner that says “Export 3D-SD” and select the last option which is to “export as an. For the last step we need to convert the model into a. You should now see a three dimensional image of your scan–pretty awesome!Ħ. We need to display it as a three dimensional image so select the little gear labeled “2D/3D” and select “3D surface rendering” which is shown below. When you first open the page you will see a normal two dimensional image. A window will appear that will tell you that the free version is not certified for medical use, click on the “I agree box” and it will take you on to the next step.ĥ. Choose the file you want and then double click on it to open it up (I would suggest doing the file that has the most images because it will give you the best model). When you open the page it should look something like thisĤ. Load the images from your CD or jump drive. Once you get OsiriX installed, open it and hit the “import button” in the top right hand corner.ģ. (.diacom is the file format that most medical imagers use) I recommend OsiriX imaging software.Ģ. Meshmixer Process 1: Convert Native Imaging File to. Next, you will need several different software packages to get everything worked out:ģ. Until 3D printed models are commonplace at the doctor, you may want to make your own! After you have imaging done, make sure to get a copy of the imaging on a cd or jump drive. How to Make a 3D print from an MRI or CT scan They are already using this technology to better prepare themselves for surgeries. In the future we can expect that doctors will take 2D scans, convert them to a 3D printed model, and use the model to explain what is going on. One of the amazing things that 3D printers can do is print models from MRI, CT-scans, and Ultrasound medical imaging. How cool would it be if you could actually hold a 3D model of your scan? You’ve been to the doctor and just gotten a CT or MRI.
