    Selling Your Medical Model Files on Embodi3D.com

    By embodi3d

    Dear Community Members, After many months of work, we are happy to announce the addition of a feature that will allow you to sell medical models you have designed on Embodi3D.com. While we always have encouraged our members to consider allowing their medical STL files to be downloaded for free, we understand that when a ton of time is invested in creating a valuable and high-quality model, it is reasonable to ask for something in return. Now Embodi3D members have two options: 1) You can share

    Easily Create 3D Printable Muscle and Skin STL Files from Medical CT Scans

    By Dr. Mike

    In this tutorial we will learn how to use the free medical imaging conversion service on embodi3D.com to create detailed anatomic muscle and skin 3D printable models in STL file format from medical CT scans. Muscle models show the detailed musculature by subtracting away the skin and fat. Even when created from a scan of an obese person, the model looks like it comes from a bodybuilder, Figure 1A. Skin models show an exact replica of the skin surface. The finest details are captured, including w

How to Easily Tell the Difference Between MRI and CT Scan

If you are planning on using the democratiz3D service to automatically convert a medical scan to a 3D printable STL model, or you just happen to be working with medical scans for another reason, it is important to know if you are working with a CT (Computed Tomography or CAT) or MRI (Magnetic Resonance Imaging) scan. In this tutorial I'll show you how to quickly and easily tell the difference between a CT and MRI.   I am a board-certified radiologist, and spent years mastering the subt

Segmentation of a foot MRI scan

So I have seen some questions here on embodi3D asking how to work with MRI data.  I believe the main issue to be with attempting to segment the data using a threshold method.  The democratiz3D feature of the website simplifies the segmentation process but as far as I can tell relies on thresholding which can work somewhat well for CT scans but for MRI is almost certain to fail.  Using 3DSlicer I show the advantage of using a region growing method (FastGrowCut) vs threshold.

Customized Medical Devices- A new trend in Medical 3D Printing

3D printing technologies have opened up the capabilities for customization in a wide variety of applications in the medical field. Using bio-compatible and drug-contact materials, medical devices can be produced that are perfectly suited for a particular individual. Another trend enabled by 3D printing is mass customization, in that multiple individualized items can be produced simultaneously, saving time and energy while improving manufacturing efficiency. 3D printers are used to manufactu

Scientists Relying on 3D Printing to Conquer Zika Virus

Very few infectious diseases in recent years have commanded the kind of attention and concern that Zika Virus has. Although Zika outbreaks have been reported in Africa, Southeast Asia and other parts of the world since the 1952, recent announcement by the Center for Disease Control and Prevention (CDC) confirming its link with microcephaly has forced everyone to sit up and take notice. The CDC estimates that the current pandemic is widespread with at least 50 countries reporting active Zika tran

3D Printed Wrist Brace

So I began to develop some pain in my right wrist which was later diagnosed as tendinitis. At the same time I had been looking at the CT scan of my abdomen and noticed they also captured my right hand as it was resting on my stomach during the scan (I had injured my right shoulder again).     I recalled a concept project a while back I had seen: the CORTEX brace. It presented the idea of replacing the typical plaster cast with a 3D printed one which would prevent the iss

Fighting Obesity with 3D Printing

Since the 1980s, three-dimensional (3D) medical printing and bioprinting technologies have been influencing almost every aspect of the human life. Most people are, however, surprised at the kind of impact additive printing is having in the field of medicine. The technology is helping diagnose and treat complex illnesses ranging from cancer and heart disease to arthritis and infections. In recent months, several innovative 3D tools have also been created to overcome obesity. More than two-thirds

Hacks to make your medical 3D Print Cheaper

Cutting down costs for 3D prints is the number one concern for many Doctors and Patients. In order to achieve this, we need to understand how costs for 3D prints are calculated. Probably the most important variable is the amount of material that is needed for printing your medical object. So all we need to do is to make sure to use as little material as possible.   Here are our some top tips for more successful 3D printing. They're short and to the point, and if you follow them, you'l

Region Growing Image Segmentation

I wanted to take some time to look into a brief history of medical image segmentation before moving into what I consider the more modern method of segmentation.  (be warned video is rather long)     First to be clear the goal of segmentation is to separate the bones or anatomy of interest from 3D scan data.  This is done most easily when there is a sharp contrast between the anatomy of interest and what surrounds it.  If you have a CT scan of an engine block this is pret

Registration with 3DSlicer

In this entry we look at registering one scan to another from the same subject pre and post op.     There may come a time when you have multiple scans of the same subject which you want to compare to each other.  This could be a CT and an MRI or a pre and post op scan as in this example.  Since the scans were taken at different times and possibly different places they will not line up with each other when they are loaded.  Registration is the process that can find the tr

How to Create a Hollow Shell from a Medical STL File Using MeshMixer

In this brief tutorial we will go over how to use Meshmixer to create a hollow shell from a medical 3D printable STL file. Hollowing out the shell, as shown in the pictures below, can allow you to 3D print the model using much less material that printing a solid piece. The print will take less time and cost less money.   For this tutorial we will use a head that we created from a real medical CT scan in a prior tutorial, " Easily Create 3D Printable Muscle and Skin STL Files from Medic

Role of 3D Printing in Scoliosis Correction Surgery

Role of 3D Printing in Scoliosis Correction Surgery

Role of 3D Printing in Scoliosis Correction Surgery     Scoliosis is a medical condition in which a person's spine has a sideways curve. The curve is usually "S" or "C" shaped. Scoliosis occurs most often during the growth spurt just before puberty.  In some cases, the person suffering from the disease can be left unable to stand up straight, to walk, or even, in the most severe cases, to breathe properly. In the most severe scoliosis cases, however, surgery is the only option.

Increasing Role of 3D Printing in Cancer Screening

In spite of extensive research, the medical fraternity has not reached a consensus on what causes cancer and how it should be treated. Nonetheless, almost everyone agrees that early and accurate diagnosis is crucial for successful recovery. In fact, early detection can lead to a 70 percent decline in cervical cancer mortality, as per the Canary Foundation. Early diagnoses of colon cancer can increase the patient’s five-year survival rate from 11 percent to 91 percent. Almost 100 percent of the p

Will 3D printed organs-on-chips replace animal testing?

Harvard University researchers have 3D printed the first organ-on-a-chip with integrated sensors. This new technology could revolutionize the biomedical research field, which has relied on expensive and time-consuming animal studies and cell cultures for decades. Organs-on-chips, or microphysiological systems (MPS), are microchips that recapitulate the microarchitecture and functions of living human organs in vitro. The Wyss Institute at Harvard University explains MPS as follows: “Each in

Overcome Hair Loss with 3D Printing

Significant thinning or loss of hair can have a detrimental impact on the individual’s overall quality of life. Men and women with unhealthy hair often suffer from emotional issues and low self-esteem. The condition may also be indicative of an underlying medical problem. As per the American Hair Loss Association, two-thirds of American men experience some hair loss by the age of 35 and about 80 percent of them have significant thinning of hair by the age of 50. Approximately half of women over
