Found "new" CSpace Prototype image.

Recently, I read a paper Dr. Refai wrote called 3D Visualization of Medical Imaging Using Static Volumetric Display, which was published in March 2010. I was impressed with what I read and was VERY surprised that I had not heard about any of it until I stumbled across the paper. The paper shed light on the progress 3DIcon has made over the last couple years and the part that surprised me most was that the paper was written almost 1 year ago in March 2010. I believe the paper provides more insight into where the technology stands than any press release the company has issued in quite some time. And again, it was written almost a year ago. (I do not have a link to the paper as I had to pay for it and don't want to violate copyright laws and distribute it. If you are interested in reading it, I'd suggest doing a search and paying the $15 or so and downloading it.)

Some highlights:

1) Image of CSpace displaying human rib cage. Seeing an image of the CSpace technology being used for a practical application is quite significant in my opinion. Beats a tea cup at least, right? According to the paper, "A set of rib cage slices captured in sagittal view and defined as a series of DICOM files were used to demonstrate the ability of CSpace to project medical images through its volume. Authors used 60 slices defined as monochrome raw data and acquired by a CT scanner...The heart and lungs have been filtered out from the slices to get only the rib cage 3D image."



2)Know how to create Green, Red, and Blue colors. "In addition to emitting a green color by the erbium Er3+ ions, the optical volume can induce a red color when the host material is doped with praseodymium Pr3+ ions. A blue color can be projected when doping with thulium Tm3+ ions." So, CSpace can achieve these three colors, though at the time the paper was written, it does not seem that it can achieve all at the same time. "It is supposed that doping the optical medium by Pr3+, Er3+, and Tm3+ ions could enable the CSpace display to produce a real, true-color 3D image."

3) CSpace software can import any images (CT, MRI, etc.) using the DICOM standard, which apparently is a standard for medical images. Someone else may have more insight into this. In the paper they go on about this quite a bit, but basically it seems that they can use existing medical imaging machines and create the necessary 3D images to better analyze data.

4) Use of Discovery 4100/ALP4.1 DLP boards will boost FPS from 8,000 to 22,727. The prototype at the time the paper was written was using one Discovery 1100 and one Discovery 3000 to achieve FPS of 8,000. I believe the Discovery 4100 is available now, so hopefully whatever prototype they have now is using that model.

The paper does a great job at describing how CSpace works and how it compares to other technologies on the market. It also describes what future improvements they would pursue. I'll try to post more diagrams of how CSpace works.
