    3D modeling and printing from US data is pretty much the same as from CT... using treshold technique and generating mesh. The biggest problem, for now, is how to open DICOM data obtained from US because it differs to one obtained from CT in one of the software for sliceing (3D Slicer). For now, in 3D slicer you can open DICOM data from GE machines and Philips but people are working on enabling importing DICOM data from other manufacturers. Hope this helps a little bit

    Agreed. This limit was put in place to prevent abuse for free downloads, but should not apply to paid items. We are working on a fix. You should now be able to download your files. Thank you for letting us know about this issue.

    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. Technical parameters: manifold STL (watertight) vertices: 462576 triangles: 925800 dimensions: 15.1 x 15.2 x 10.5 cm

    We 3D printed this model for a customer and the print turned out beautifully. The parts stack nicely and by opening them up, you can clearly see the detailed structures inside the heart chambers. To learn more about our 3D printing service, click here.

    Skull is seen as two shells

    Dear olatif2 when in blender, choose edge select and then ALT + LMB/RMB (depending your preferences) and it should select whole edge (tabula externa) than try SHIFT+ALT+LMB/RMB and select tabula externa and than when both edges are selected pres F and sgould get a facet (closed gap). Or faster way would be to add a new object (cube), size it up, put it below both edges and boolean operation difference and should get closed edges of the skull but slightly lower model than it would be at first.

    This 3D printable model of a normal human heart was generated from an ECG-gated contrast enhanced coronary CT scan. The slices are cut to illustrate the echocardiographic short-axis view. If you are interested in a 3D printable heart that shows slices in the anatomical transverse plane, click 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. There is a sturdy and stable base. Individual slices show the detailed cardiac anatomy of the right and left ventricles, and right and left atria, and outflow tracts in echocardiographic short-axis projection. Perfect for educational purposes. Technical parameters: Individual STLs: 4 Mesh integrity: manifold STL (watertight) vertices: appx 550k per object triangles: appx 1.1M per object dimensions: 11.4 x 9.1 x 10.6 cm

    We recently 3D printed a multimaterial skull with MCA aneurysm from a CTA head for customer who needed the skull in rigid plastic and the vessels and aneurysm in flexible material. The model will be used by neurosurgeons to practice intracranial aneurysm clipping surgery. To properly simulate the surgery, the skull needs to be hard and the vessels elastic. Combining two materials (and two printers!) provides the best solution. The model was created on democratiz3D. You can learn more about embodi3D's printing service here.

    I've only printed the skull, but it came out very well (see my comment), I haven't had to clean none of the surfaces of the file. Again, thanks for sharing this file 🙂

    Great blog! Its the easiest way in which someone must have explained the difference between CT scan and MRI scan. Thanks for sharing such a wonderful blog, most of the people would like it. I would also like to know the difference between Ultrasound, MRI, and CT scan.

    This model is the right lower extremity bone rendering of a 65-year-old male with left thigh myxoid fibrosarcoma. At the time of diagnosis, the patient had metastases to his lungs. The patient therefore underwent neoadjuvant radiotherapy, surgery, and adjuvant chemotherapy and was found to have an intermediate grade lesion at the time of diagnosis. The patient is still living with the metastatic disease at 2.5 years since diagnosis. This is an STL file created from DICOM images of his CT scan which may be used for 3D printing. The leg includes the area between the knee and the ankle and houses the tibia and fibula. The proximal tibia includes the medial plateau (which is concave) and the lateral plateau (which is convex). The Proximal tibia has a 7-10 degree posterior slope. The tibial tuberosity is located on the anterior proximal tibia, which is where the patellar tendon attaches. On the anteromedial surface of the tibia is Gerdy's tubercle, where the sartorius, gracilis, and semitendinosus attach. The distal tibia creates the superior and medial (plafond and medial malleolus) of the ankle joint. The proximal fibula is the attachment for the posterolateral corner structures of the knee joint. The peroneal nerve wraps around the fibular neck. The distal fibula is the lateral malleolus and a common site for ankle fractures. The ankle is a hinge (or ginglymus) joint made of the distal tibia (tibial plafond, medial and posterior malleoli) superiorly and medially, the distal fibula (lateral malleolus) laterally and the talus inferiorly. Together, these structures form the ankle “mortise”, which refers to the bony arch. Normal range of motion is 20 degrees dorsiflexion and 50 degrees plantarflexion. Stability is provided by the anterior talofibular ligament (ATFL), calcaneofibular ligament (CFL), and posterior talofibular ligament (PTFL) laterally, and the superficial and deep deltoid ligaments medially. The ankle is one of my most common sites of musculoskeletal injury, including ankle fractures and ankle sprains, due to the ability of the joint to invert and evert. The most common ligament involved in the ATFL. The foot is commonly divided into three segments: hindfoot, midfoot, and forefoot. These sections are divided by the transverse tarsal joint (between the talus and calcaneus proximally and navicular and cuboid distally), and the tarsometatarsal joint (between the cuboids and cuneiforms proximally and the metatarsals distally). The first tarsometatarsal joint (medially) is termed the “Lisfranc” joint, and is the site of the Lisfranc injury seen primarily in athletic injuries. This model was created from the file STS_022.

    Hi Dr Mike , In principal, is it the same procedure using 3D ultrasound DICOM files? Many thanks upfront Tom
