We have recently uploaded some new videos of 3D scans captured using our innovative new scanning technology. This 3D scanning system gives us complete water-tight meshes with incredible detail and resolution. The system is ideal for digital archiving, reverse engineering, digitizing and much more. Stay tuned to Criteria Systems as we continue to break new ground in the field of 3D scanning and 3D scanning applications.
As with all of our scans, these models can be reproduced or reduced in size using our rapid prototyping system, or they can be enlarged for large format CNC production.

3D Scanning and Rapid Prototyping for Medical Purposes
3D Scanning and Rapid Prototyping at Criteria Systems are outstanding tools for medical applications.
For instance, The Walter Reed Army Medical Center in Washington, D.C. is using 3D rapid prototyping to create multi-color physical models of anatomy to aid in performing delicate surgeries.
Beginning with CT scans or photos, the institution’s 3D Medical Applications Center transforms them into 3D files, applies any color to the resulting digital models, and then uses a 3D printer to produce multicolor physical models. These models can be held in the hand and examined from all angles, which helps surgeons get a better idea of what issues they will need to know about during surgery. Currently, the center prints several of these models per week.
In particular, neurosurgeons have found the models useful as they make models of aneurysms and arterio-venous malformations to help them perform delicate surgeries. This way, surgeons report that they can know in advance the anatomical structures of the patient rather than discovering them after the incision is made, thus lessening the possibility of blood loss and chances of infections.
For orthopedic use, surgeons created a model for removal of bony growths on a patient’s knee. Surgeons used a 3D printer to print a white model of the joint with blood vessels illuminated in red and nerves in yellow, which gives the surgeon a roadmap to figure out the best route to address the tumors.
In one case, the surgeon used a sterile bag to transport his model into the operating room. He aligned his cutting instrument on the model, then aligned his instrument on the patient in the same manner.
For constructing facial prosthetic models, a 3D printed mask is used in anaplastology to avoid the process of plaster on patients’ faces used to produce a moulage casting.

New Criteria Systems Website Online
Criteria Systems proudly announces the re-launching of our website. The new site features more content, and a better navigation. Furthermore the new website puts our corporate identity into a new light.
Since our inception in 2007, Criteria Systems has worked to develop and improve our website delivery. Now we have completely overhauled the site to bring a new exciting and clear corporate vision to our customers. We are also taking this opportunity to showcase our new product and service offerings, including our status as an authorized value-added reseller of AutoCAD 2010 software.
The new website features an easy-to-follow navigation, more dynamic content and more comprehensive information about our products and services. Each page features a consistent drop-down menu and other navigation tools make the site very simple to work-through. Lots of Flash content demonstrates how each of our applications and offerings are presented. Dynamic content such as this also emphasizes the 3D work we undertake at Criteria Systems. A key development of the re-worked site has been to provide better content so that our customers are empowered with the knowledge and tools they need.
Apart from the look of the site, there are a great many 'under-the-hood' improvements that should help us increase our exposure and search engine rankings.
The initial feedback on the in-house designed and built site has been so positive, that we have decided to offer website design as one of our design services. "The look and feel of the site is great," comments one reviewer, "it takes Criteria Systems to a whole new level." Stay tuned to www.criteria-systems.com in the future as we continue to push the boundaries of website design.

3D Scanning Applications
3D Laser scanning is the process of measuring any given object by means of a laser beam and digitizing the information.
Our scanning systems work by reading a reflected laser beam off of the original object. The scan system then builds a 3D model of the object. This model can be modified in a CAD-system or used for copying the exact shape, or rapid prototyped out as a one to one or scaled version of the original.
With our latest scanning technology it is also to capture the color of an object. This can be used on a prototype as well. 3D Scanning with Criteria Systems can therefore be used to:

- reduce/eliminate CAD development time
- shorten development periods
- enter the market much faster
