    Medical 3D printing 101

    By valchanov

    Bones   The main advantage of the orthopedical presurgical 3d printed models is the possibility to create an accurate model, which can be used for metal osteosynthesis premodelling - the surgeons can prepare (bend, twist, accommodate) the implants prior the operation. After a sterilisation (autoclaving, UV-light, gamma-ray etc etc), those implants can be used in the planned surgery, which will decrease the overall surgery time (in some cases with more than an hour) with all it's advant

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

Dicom Primer

In this tutorial I will cover some of the basics on working with dicom data with a focus on anatomizing, and reading into medical imaging software as well as how to potentially fix problematic scans.     So first of all what is DICOM data?  It is a standard file type for basically all medical imaging devices (CT, MRI, US, PET, X-ray, etc), DICOM stands for Digital Imaging and COmmunication in Medicine and along with the file format, and the tags, it is designed to be tra

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

Atlas and Axis, 3D PDF

Hello My recent anatomy projects forced me to start importing my 3d models into 3d pdf documents. So I'll share with you some of my findings. The positive things about 3d pdf's are: 1. You can import a big sized 3d model and compress it into a small 3d pdf. 40 Mb stl model is converted into 750 Kb pdf. 2. You can run the 3d pdf on every computer with the recent versions of Adobe Acrobat Reader. Which means literally EVERY computer. 3. You can rotate, pan, zoom in and zoo

The Benefits of Additive Manufacturing Applies to 3D Printed Pills and Medication

In August 2015, the U.S. Food and Drug Administration (FDA) approved the first three-dimensional (3D) printed drug for commercial use when it allowed Pennsylvania-based Aprecia Pharmaceuticals to manufacture and market its anti-epileptic pill Spritam. The company relied on additive printing technology to create a rapidly dissolving pill that could be consumed with very little water. One of the main goals was to benefit patients who are unable to swallow medications, especially during an epilepti

How to create an NRRD file from a DICOM Medical Imaging Data Set

How to create an NRRD file from a DICOM Medical Imaging Data Set

NRRD is a file format for storing and visualizing medical image data. Its main benefit over DICOM, the standard file format for medical imaging, is that NRRD files are anonymized and contain no sensitive patient information. Furthermore NRRD files can store a medical scan in a single file, whereas DICOM data sets are usually comprised of a directory or directories that contain dozens if not hundreds of individual files. NRRD is thus a good file for transferring medical scan data while protecting
