    Dr. Mike got a reaction from Plex for a file, 3D Printable Human heart model with stackable slices   
    -> IMPROVED VERSION OF THIS FILE IS AVAILABLE HERE <--
     
    This 3D printable model of a human heart was generated from a contrast enhanced CT scan. The model comes in 4 slices, and demonstrates the detailed anatomy of the human heart in exquisite detail. Each slice stacks on top of the prior slice to form a complete human heart. Individual slices show the detailed cardiac anatomy of the right and left ventricles, and right and left atria, and outflow tracts. Perfect for educational purposes.

    Dr. Mike reacted to valchanov for a file, Thoraco-abdominal aneurysm, preoperative model.   
    This is a preoperative model of thoraco-abdominal aneurysm, Crawford typle I, with rupture above the diaphragm. The subsequent haemorrhagia in the mediastinum closed temporary the rupture, probably saving the life of the patient. This was an impossible operation, which took 7 hours and the team of the best cardio-thoracic surgeons in Bulgaria. I don't know how, but the patient is still alive and kicking. It took me 3 days to make the model and to turn it into a 3d visualization and I'll share my workflow with you. I'm printing the model right now for a cardio-thoracic surgery symposium.
    The source is Angio CT scan with 1,3 mm slide thickness.
    1. I analysed the model in Radiant Dicom viewer (you can activate trial license for unlimited amount of times, if you can't afford 100 euro for it). I selected the best series and exported them in a folder.
    2. I loaded the model in 3D Slicer. First, I run two denoising algoritms (Gradient Anisotropic Diffusion and Curvature Anisotropic Diffusion), which improved the quality of the images significantly. Then I selected a ROI, which included the whole aorta. With the Segment Editor Module I segmented the lumen of the aorta. Then, as a separate segmentation, I used the Margin operation to grow the lumen with 2 centimeters and applied a boolean operation, resulting in a hollow shell with precise lumen. I had to segment the rest of the aortic wall manually. I exported the result as STL file.
    3. In Meshmixer, I modeled the whole thing, until I was satisfied by the result.
    4. My client asked me to remove the aortic arch (it's such a pain, I love aortic arches) and to print the aneurysmal sac with the abdominal aorta and the bifurcation of the iliac arteries. Note the double renal artery. I divided the model into two parts and installed ports for two 8x2mm and two 5x2 mm neodymium magnets with tolerance of 0,250mm. The final preprint version is on picture 3.
    5. I'm printing this model with 1,5mm slide thickness, 4 perimeters, 15% gyroid infill, custom support with support enforcers, using red Natural PLA from a local manufacturer. The whole printing will take 45 hours.

    Dr. Mike got a reaction from Alyboba for a file, 3D Printable Human Heart model (Improved) with stackable slices, STL format   
    This 3D printable model of a human heart was generated from a contrast enhanced CT scan.  This model is an improvement over a prior version (here). It shows the heart with slices cut in the anatomical transverse plane. If you are interested in a heart with short-axis slices, check out my short-axis stackable slice model here.

    Notches have been added to ensure the slices fit together and do not slide against each other. The model demonstrates the detailed anatomy of the human heart in exquisite detail. Each slice stacks on top of the prior slice to form a complete human heart. Individual slices show the detailed cardiac anatomy of the right and left ventricles, and right and left atria, and outflow tracts. Perfect for educational purposes. It has been validated as printable on an Ultimaker 3 Extended printer.
