Using 3D Printed Liver Models for Guidance During Liver Surgery

Using 3D Printed Liver Models for Guidance During Liver Surgery

Researchers from Nagoya University in Japan are now using customized 3D printed liver models created from patient Computer Tomography (CT) scans for guidance during liver surgery, as reported at the 2014 Radiological Society of North America meeting. The human liver is a complex organ. Liver cells, called hepatocytes, do the work of cleaning the blood of toxins and waste -- the primary function of the liver. Hepatocytes are dependent on a complex network of vascular structures, including bile du

Spine STL files from CT Scans for 3D printing cervical, lumbar, thoracic vertebrae for medical modeling - Download Free Collection

Spine STL files from CT Scans for 3D printing cervical, lumbar, thoracic vertebrae for medical modeling - Download Free Collection

I have received several requests for spine STL files from CT scans and these files have been added to the file vault over time as more people are 3D printing vertebrae for medical moldeling. There was a really good response to my last article about the wonderful 3D printable skull models available for free download on the embodi3D.com website. So, I've decided to do another article about spine models.   Embodi3D.com contains a large collection of spine STL files within the Spine and Pe

Saving a Spleen with 3D Printing: Pre-Surgical Planning with Medical Models make "Impossible"  Surgeries Possible.

Saving a Spleen with 3D Printing: Pre-Surgical Planning with Medical Models make "Impossible" Surgeries Possible.

Summary: 3D printing is making rapid advances in many areas of medical treatment. In this article, I'll describe how I used recent advances in 3D printing to save a patient from having to have her spleen removed. In the process I broke some new ground in use of 3D printing in surgical planning. The clinical case and 3D printing advances are described in a recently published peer-reviewed paper in the medical journal Diagnostic and Interventional Radiology.   Intro image: The author usi

Review of the Ultimaker 3 Extended 3D Printed for Medical Applications

Review of the Ultimaker 3 Extended 3D Printed for Medical Applications

Here is my video review of the Ultimaker 3 Extended for medical 3D printing. It was 4 months in the making. Medical anatomical models can be challenging to 3D print because of complex anatomy and large size. This 3D printer has a couple of features which help overcome these challenges. Ultimaker 3 Extended specfications and pricing.   First, the Ultimaker 3 is a dual extrusion printer which allows for two different materials to be used during a single print. This video shows 3D print

Revealing the Beauty of the Microscopic World Through 3D Printing

Revealing the Beauty of the Microscopic World Through 3D Printing

There is tremendous beauty and diversity in nature that goes unnoticed by humans because it is simply too small for us to see and appreciate. Embodi3D member Michael Holland hopes to change that. Via his eponymous company Michael Holland Productions, he has created a fascinating traveling museum exhibit called MacroMicro that reveals the striking complexity and beauty of the microscopic world through high-resolution micro-CT scanning and 3D printing. On the remote island of Iriomote-jima, p

Invasive Heart Surgery Avoided as Advances in 3D Printing Improve Safety of Transcatheter Aortic Valve Replacement (TAVR)

Invasive Heart Surgery Avoided as Advances in 3D Printing Improve Safety of Transcatheter Aortic Valve Replacement (TAVR)

3D printing is revolutionizing the treatment of aortic stenosis, as reported by researchers from St. Joseph's Hospital in Phoenix, Arizona and presented at the 2014 Radiological Society of North American (RSNA) meeting. Aortic stenosis is a deadly condition where the valve that connects the heart to the aorta does not open properly. The aortic valve, as it is called, is designed to open freely to allow blood pumped from the heart to move in a forward direction into the aorta, the main artery of

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
