  7. Welcome to this week's Top Ten, featuring some exciting STL files and medical models, many of which you can download and print using your own 3D printing machine. When you upload your organ STL files to embodi3d®, you are helping researchers, students, and inquisitive minds everywhere to develop innovative diagnostic, interventional, and surgical techniques. Medical 3D printing can be used to create centimeter- to sub-millimeter-accurate models. These include the hearts, lungs, kidney, and colon featured in this week's Top Ten, but can be used to create just about any type of 3D organ or tissue model. The democratiz3D® conversion algorithms used on the embodi3D® website are sophisticated enough to recreate the cellular arrangements of various tissues and organs, but are straightforward enough to be used by just about everyone. Even the complex anatomy of the heart can be successfully replicated using various pliable 3D printing materials. These models could serve a future role in preoperative planning, medical education, and enhanced communication between radiologists and others involved in patient care. The prospect of 3D medical models being used to advance research and educational knowledge is truly exciting. We're glad to have you along to share in the experience of this rapidly developing science and art form. But, to receive much of what embodi3D® has to offer you have to register on the website. But, signing up is absolutely free. Become a Registered Member (it's Free) Remember to register on embodi3D.com so you can upload, download, share, and create stunningly realistic 3D models of hearts, lungs, mandibles, and just about anything having to do with the human anatomy. Plus, it is absolutely free to become a registered member. #1. 3D-Printable Model of Human Heart in Tissue Slices Dr. Mike created and submitted this 3D-printable human heart, separated into stackable slices for educational purposes. This STL file originated from a contrast-enhanced CT scan. The embodi3D® community was very excited about this model; it demonstrates the complex anatomy of the heart in a way that can be held, studied, taken apart, and put back together — all activities real-life patients would rather you not try with their own hearts. Representing some of the best uses of medical 3D printing on the embodi3D.com website, this downloadable STL file has earned a rightful place on this week's Top 10 downloads list. #2. Create a 3D Model of a Heart and Pulmonary Artery Tree This anatomically accurate heart and pulmonary artery tree was extracted from a CT angiogram DICOM dataset (0.4 mm slice thickness x 300 slices). This model may serve as an excellent, hands-on educational tool for those entering the medical profession. The uploaded STL files shows the aorta, coronary sinus, coronary arteries, pulmonary arteries, as well as the cardiac ventricles and atria. A special "thank you" goes out to Health Physics for contributing this magnificent file! #3. Full-Size Model of a Human Heart Number 3 on our list is a 3D-printable model of a full-size human heart. Using this STL file, you can create a scale model of a heart, complete with all the complex cardiac anatomy. You will achieve the best results by using a flexible medium when completing your 3D print. Please note: This model has yet to be fully optimized for 3D printing. Therefore, some issues related to minimum wall thickness can be expected. #4. Great Example of a 3D-Printable, Anatomically Accurate Human Heart Dr. Marco Vettorello graciously created and shared this highly accurate human heart STL file, ready for use in your 3D printer. Thank you, Dr. Vettorello! #5. 3D-Print and Compare a Healthy Lung to a Lung with COPD Lung tissue inflammation in patients with chronic obstructive pulmonary disease (COPD) makes it difficult to fully expel air and creates an obstruction in breathing in fresh air. To compare the three STL files of a lung with COPD, embodi3D® has also uploaded three files of a healthy lung. Chronic obstruction pulmonary disease chronic lung disease is often caused by long-term exposure to particulates, cigarette smoke, harmful gases, and other irritants. Those with COPD are at a higher risk of developing heart disease, lung cancer, and a number of other life-threatening conditions. #6. Have a Heart... in a Medical 3D Printing-Ready Format! We'd like to say a special "thank you" to the creators of this 3D-printable heart file, Dr. Beth Ripley and Dr. Tatiana, who have graciously shared this 3D-printable human heart in STL format. This file originally appeared in the "Top 10 Killers" list. While it appears in sixth place for this week's chart, the cardiac events we collectively refer to as "heart disease" remain the developed world's top "killer" and these files should serve to remind us why this type of research is so important — not only to the medical community, but the many patients cardiovascular disease affect each day. #7. 3D-Print a Lung with Pneumonia Pneumonia is one of the leading causes of hospitalization in many parts of the world. This inflammatory condition affects the microscopic alveoli (tiny air sacs) of the lungs, which leads to coughing, sneezing, and difficulty breathing. The 3D-printable files uploaded in STL format feature the lung, airways, and detailed imaging of the alveoli. #8. Compare Healthy and Diseased Kidneys by Creating a 3D Model Chronic kidney disease (chronic renal disease) presently affects around 26 million American adults, with many others at risk of developing this devastating disease. The STL files uploaded for your medical 3D printing use allow you to compare a healthy kidney to one with chronic renal disease. These are available in a format that is ready to be 3D-printed to create your three-dimensional model. #9. Create a 3D Model of a Human Colon with this STL File Surgical procedures, such as hemorrhoidectomies, require a surgeon with a solid grasp of three-dimensional human anatomy. By uploading and sharing medical 3D printing-ready files, such as this colon extracted from a CT DICOM dataset (0.8 mm slice thickness x 467 slices), those entering the profession can acquire this essential knowledge outside the confines of the operating room. Available for educational purposes, this 3D model includes the cecum, appendix, and overall layout of the small and large bowel. #10. A democratiz3D®-Created, 3D-Printable STL File of a Human Right Kidney Dr. Mike uploaded this printable STL file of a human kidney (right side), showing all the nuances of the kidney and renal collecting system in clear, stunning detail. Dr. Mike used the democratiz3D® premium tissue algorithms to bring out all the details of the kidney. Sharing 3D-printable files is just one of the many ways users are creating the future of preoperative planning and surgical performance. References 1. Zheng, B., Wang, X., Zheng, Y., & Feng, J.

  8. The human heart beats an astonishing 115,000 times each day. It's a fascinating (and essential) organ, which is why we are highlighting the heart and its support structures in this week's post, as well as sharing some intriguing STL files so you can create your own heart 3D model by using your own 3D printer. In this week's post, we will introduce you to the top 3D-printable STL files published on the embodi3D® website. Before you get started creating your own heart 3D model, you will need to register through embodi3D® (https://www.embodi3d.com/register/). Registering is absolutely free, so become a member today! We recently reported on how researchers have used a 3D printed heart to treat arrhythmia, yet 3D printing is also be used to combat other types of cardiovascular disease. After all, heart disease is the leading cause of premature death in Western countries. According to the National Institutes of Health, nearly half a million individuals succumb to cardiovascular disease each year. While coronary artery disease leads the pack in terms of cardiovascular diseases, congenital heart conditions and acquired diseases of the heart such as tumors, cardiomyopathy, pericardial processes, and valvular disease unfortunately remain present in the modern era. In the early 2000s, an average 1.5 million patients received some type of invasive heart catheter, a figure brought to our attention through the book "Computed Body Tomography with MRI Correlation, Volume 1" (edited by Joseph K. T. Lee). The answer to reducing the number of invasive heart procedures may be in medical 3D printing, whether CT scans can be converted into STL files in order to create 3D models of the heart and nearly every part of the human anatomy. Medical 3D Printing and STL Files: An Alternative to Invasive Cardiac Catheterization? Echocardiography is widely available, portable, and essentially non-invasive when compared to MDCT and MR scans, while CT and MRI scans give us a clear advantage in terms of creating output files that are ready to be converted into a 3D printing-ready format such as STL (stereolithography) files. STL files and tissue algorithm conversion technologies from companies such as embodi3D® are bringing medical 3D printing within reach of researchers, radiologists, physicians, and medical students. Radiologists have witnessed the evolution of medical imaging, from two-dimensional scans to the three-dimensional scans aided by the latest technologies. 3D-printable files open the door to less invasive diagnostic procedures and have also proven useful in pre-surgical planning. Multiplanar imaging with computed tomography (CT) and magnetic resonance imaging (MRI) gave rise to 3D reconstructions, improving the evaluation of complex anatomies. Medical 3D printing takes imaging data from the limited two-dimensional view on a computer screen to a three-dimensional model that can be held, studied, and referenced. The Meteoric Rise of Additive Manufacturing in Medicine The additive manufacturing technique known as 3D printing has seen exponential growth in health care sectors over the last decade, with most of that growth coming in just the last few years. As a tool to improve patient care and lower the costs of care, 3D printing can be used in pre-operative planning, education, and also to replace bone materials, such as knee joints. For these reasons, the McKinsey Global Institute recently called 3D printing a "disruptive technology that will transform life, business and the global economy." This management consulting company also predicated that 3D printing will have impact the global economy by a range of $200 billion to $600 billion in the coming decade. What started out as a technology for garage tinkerers and those looking to replace hard-to-find mechanical parts was only recently introduced into the medical world. The adoption rates of this technology within the health care community have been staggering. In 2000, only six publications made mention of 3D printing's use in medicine. That figure had jumped to nearly 200 publications in the years spanning 2011 and 2015. This brings us to the present, where nearly 2,000 publications have cited the amazing utility of 3D printing across a diverse range of medical applications. The National Additive Manufacturing Innovation Institute was launched in 2012 as a way to grow and encourage the adoption of this life- and industry-changing technology. 3D Printing in Cardiology and Cardiothoracic Surgery The use of 3D printing in cardiology to detect abnormal heart structures and predict heart attacks has followed a similar growth trend in the past decade. In the research article "Cardiac 3D Printing and its Future Directions," Vukicevic, et al. detailed the utility of 3D printing in the area of cardiovascular care, focusing primarily on acquired structural heart disease. 3D-printed heart and aortic models have been used for treatment planning in both percutaneous cardiology applications and cardiothoracic surgery. In cardiothoracic surgery, 3D-printed anatomic models have been used to plan surgical approaches, perform resections, and guide the process of tissue reconstruction. Computed tomography angiography (CTA) is frequently performed before catheter-based and surgical treatments in situations of congenital heart disease (CHD). To date, little is known about the accuracy and advantage of different 3D-reconstructions in CT-data. For reference purposes, gaining the exact anatomical information is critical in achieving a successful outcome. According to a review published in JACC: Basic to Translational Science, 3D models may improve outcomes in patients with congenital heart disease by also improving communication among multidisciplinary teams, enhancing shared decision-making, and facilitating greater medical breakthroughs via basic science and translational clinical investigations. Approximately 3 out of 1,000 patients with congenital heart disease require a surgical or catheter-based intervention early in their lifetimes, according to the study's investigators. 3D printing can be a valuable tool to plan extra-cardiac and vascular surgery in patients with CHD. 3D models are helpful for planning high-risk unifocalization surgery. Medical 3D Printing as an Educational Tool in Congenital Heart Disease In terms of education, the use of medical 3D printing technology may lead to an educational shift from an apprenticeship-type model to a simulator-based learning method, which would augment the traditional mentored training. Using 3D printed models in congenital heart disease (CHD) can reduce the learning curve for cardiac trainees in three crucial ways: help trainees understand the complex cardiovascular structures, provide high-fidelity simulation experiences, and enable more exposure to rare CHD cases. 1. A 3D-Printable Model of a Human Heart from Contrast-Enhanced CT Scan A 3D-printable model of a human heart was generated from a contrast-enhanced CT scan. An endpoint of many patients with coronary heart disease (CHD) is heart failure requiring a ventricular assist device (VAD) or heart transplant. 3D printing can aid in ventricular assist device placement and optimizing function in complex CHD, as recently described by Farooqi et al. and Saeed et al. 2. 3D-Printable STL File of Truncus Arteriosus with Unseparated Aorta and Pulmonary Artery Truncus arteriosus is a congenital (present at birth) defect that occurs due to abnormal development of the fetal heart during the first 8 weeks of pregnancy. The heart begins as a hollow tube, and the chambers, valves, and great arteries develop early in pregnancy. The aorta and pulmonary artery start as a single blood vessel, which eventually divides and becomes two separate arteries. Truncus arteriosus occurs when the single great vessel fails to separate completely, leaving a connection between the aorta and pulmonary artery. This model is provided for distribution on Embodi3D with the permission of the author, pediatric cardiologist Dr. Matthew Bramlet, MD, and is part of the Congenital Heart Defects library. We thank Dr. Bramlet and all others who are working to help children with congenital heart problems lead normal and happy lives. 3. STL Files of a Neonatal Heart Defect (Ventricular Septal Defect) Ventricular septal defect (VSD) with pulmonary atresia (PA) can be considered to be the severest form of tetrology of Fallot wherein the right ventricular outflow tract obstruction has progressed to the extent of atresia. This atresia can occur either at the infundibulum or as a plate atresia of the pulmonary valve. An important observation is that the plate-type atresia is more frequently associated with well-developed pulmonary arteries. The other significant abnormality in patients with VSD and pulmonary atresia (PA) is the presence of arborization abnormalities. The blood supply to a particular lung segment can be derived from a systemic artery or a central pulmonary artery or a combination of both. 4. 3D-Printable Heart Model Showing Tetralogy of Fallot Tetralogy of Fallot, which is one of the most common congenital heart disorders, comprises right ventricular (RV) outflow tract obstruction (RVOTO) (infundibular stenosis), ventricular septal defect (VSD), aorta dextroposition, and RV hypertrophy (see the image below). The mortality rate in untreated patients reaches 50% by age 6 years, but in the present era of cardiac surgery, children with simple forms of tetralogy of Fallot enjoy good long-term survival with an excellent quality of life. This three-part 3D printed heart is from a CT scan of a 4-year-old infant with Tetrology of Fallot, a congentital heart defect and the most common cause of blue baby syndrome. 5. 3D-Printable STL of Left Heart Atrium and Ventricle 3D models promise to transform teaching in ways that go beyond the lecture hall, and over the next few years are set to revolutionize medical training, especially in percutaneous interventions. In this 3D model we can observe the anatomical relationship of all the elements of the heart and neighboring structures. 6. Left Main Coronary Artery with Abnormal Origin Rising from Pulmonary Artery Trunk Variations in coronary anatomy are often seen in association with structural forms of congenital heart disease like Fallot's tetralogy, transposition of the great vessels, Taussig-Bing heart (double-outlet right ventricle), or common arterial trunk. Importantly, coronary artery anomalies are a cause of sudden death in young athletes even in the absence of additional heart abnormalities. Prior knowledge of such variants and anomalies is necessary for planning various interventional procedures. 7. Aortic Coarctation in 3D-Printable STL File Coarctation of the aorta — or aortic coarctation — is a narrowing of the aorta, the large blood vessel that branches off your heart and delivers oxygen-rich blood to your body. When this occurs, your heart must pump harder to force blood through the narrowed part of your aorta. Coarctation of the aorta is generally present at birth (congenital). The condition can range from mild to severe, and might not be detected until adulthood, depending on how much the aorta is narrowed. Coarctation of the aorta often occurs along with other heart defects. While treatment is usually successful, the condition requires careful lifelong follow-up. 8. STL File of a Cardiac Myxoma The World Health Organization (WHO) defines a cardiac myxoma as a neoplasm composed of stellate to plump, cytologically bland mesenchymal cells set in a myxoid stroma. Myxomas can recur locally (usually with incomplete resection) and spread to distant sites through embolization. Embolization appears to be much more likely in myxomas that are friable with a broad-based attachment than they are in tumors that are fibrotic or calcified. 9. 3-D Printable Heart Anatomy from High-Spatial Resolution Imaging A heart 3d model with details of anatomy. By combining the technologies of high-spatial resolution cardiac imaging, image processing software, and fused dual-material 3D printing, several hospital centers have recently demonstrated that patient-specific models of various cardiovascular pathologies may offer an important additional perspective on the condition. With applications in congenital heart disease, coronary artery disease, and in surgical and catheter-based structural disease – 3D printing is a new tool that is challenging how we image, plan, and carry out cardiovascular interventions. 10.

  15. There are many challenging cases, in which the single segmentation is not enough. The paranasal sinuses and the congenital heart defects are notable examples. My usual workflow was to segment whatever I can as good as it's possible, to clean the unnecessary structures and the artefacts, to export the segmentation as stl 3d model and then to "CAD my way around". This is solid philosophy for simple, uncomplicated models, but for complex structures with a lot of small details and requirement from the client for the highest quality possible, this is just not good enough, especially for a professional anatomist like myself. Then I started to exploit the simple fact, that you're actually able to export the model as stl, to model it with your CAD software and then to reimport it back and convert it into label map again. I called this "back and forth technique". You can model the finest details on your model and then you can continue the segmentation right where you need it, catching even the slightest details of the morphology of the targeted structure. This technique, combined with my expertise, gives me the ability to produce the best possible details on some of the most challenging cases, including nasal cavity, heart valves, brain models etc. etc.To use this technique, just import the stl file, convert it into a label map (for 3D slicer - segmentation module/ export/import models and label maps). The main advantages of this technique are:1. You can combine the segmentation with the most advanced CAD functions of your favorite software. Two highly specialized programs are better than one "Jack of all trades" (cough cough Mimics cough cough)2. Advanced artefact removing.3. Advanced small detail segmentation and modelling.4. Combined with several markers (separate segmentations, several voxels in size) on the nearby anthropometric points, this technique increases the accuracy of the final product significantly. Without points of origin, the geometry of your model will go to hell, if you're not especially careful (yes, I'm talking about the 3D brushes in Slicer).5. You can easily compare the label map with the 3d model, converted back. Every deviation, produced during the CAD operations will be visible like a big, shining dot, which you can easily see and correct. This is one of the strongest quality control techniques.6. You can create advanced masks with all the geometrical forms you can possibly imagine, which you can use for advanced detail segmentation. Those masks will be linked with the spatial coordinates of the targeted structures - the stl file preserves the exact coordinates of every voxel, which was segmented.7. You can go back and forth multiple times, as many as you like.8. This technique is more powerful than the best AI, developed by now. It combines the best from the digital technologies with the prowess of the human visual cortex (the best video card up to date).The main disadvantages are:1. It's time consuming.2. It produces A LOT of junk files.3. Advanced expertise is needed for this technique. This is not some "prank modelling", but an actual morphological work. A specialized education and practical experience in the human anatomy, pathology and radiology will give you the best results, which this technique can offer. 4. You need highly developed visual cortex for this technique (dominant visual sense). This technique is not for the linguistic, spatial-motor, olphactory etc. types of brains. Recent studies confirms, that a part of the population have genetically determined bigger, more advanced visual cortex (The human connectome project, Prof. David Van Essen, Washington University in Saint Louis). Such individuals become really successful cinematographers, designers, photographers and medical imaging specialists. The same is true for all the other senses, but right now we're talking about visual modality and 3D intellect (I'm sorry, dear linguists, musicians, craftsmen and tasters). It's not a coincidence that I have so many visual artists in my family (which makes me the medical black sheep). But if you don't have this kind of brain, you can still use the technique for quality control and precise mask generation. Just let the treshould module or the AI to do the job for you in the coordinates, in which you want (You should really start using the Segment Editor module in Slicer 3D).5. You really need to love your work, if you're using this technique. For the usual 3D modelling you don't need so many details in your model and to "CAD your way around" is enough for the task.6. You should use only stl files. For some reason, the obj format can't preserve the spatial geometry as good as the stl format. Maybe because the stl is just a simple map of vertex coordinates and the obj contains much more sophisticated data. The simple, the better.On the picture - comparison of the semilunar valves, made by treshould segmentation at 250-450 Hounsfield units (in green) and modelled and reimported model (in red).
