NAV-3D Launches New Line Of Glasses Free 3D Media Players And Cameras At Photo Plus Expo 2012
3D-News Posted: Wednesday, November 14, 2012 (8:48 UTC) | Posted By: Webmaster

NAV-3D Technologies, a pioneer in the field of 3D multimedia entertainment devices, announced the launch of their new line of glasses free 3D media players, cameras and camcorders. Incorporating the latest advancements in 3D technology, three new NAV-3D media players eliminate the need for users to wear 3D glasses to view 3D content, and three new NAV-3D digital cameras make it easy to capture and share 3D photos and videos in ways never thought possible.

Last month at the PDN Photo Plus International Expo, NAV-3D introduced a unique line of innovative 3D multimedia entertainment devices. Those in attendance participated in hands-on demonstrations and interactive film sessions.

"We are really excited about the NAV-3D product line," said Matthew Gross, CEO and Founder of NAV-3D. "Seeing everyone's reaction for the first time is like watching kids in a candy store. I don't think we could have predicted such an overwhelmingly favorable response to an initial product launch."

The NAV3D6, NAV3D8 and NAV3D8B digital media players come equipped with a stereoscopic 6" or 8" parallax barrier 3D display. The parallax barrier is a layer of material embedded into the screen that contains a set of precision slits, forcing each eye to see a unique set of pixels, creating a sense of depth.

"I could see you putting this in front of a kid and having them be enthralled for hours," said Tarina Peterson, a professional graphic designer from NYC. "This is like instant entertainment."

The NAV3DCAM-12 can capture 3D videos in high definition (1920x1080 resolution) or up to 16.0-Megapixel still images (with interpolation) while letting users preview the 3D effect instantly using a 3.2" parallax display 3D viewfinder. The NAV3DCAM-10 and NAV3DCAM-11 incorporate this same 3D display technology, but capture videos with a maximum of WVGA or 720P resolution (respectively).

NAV-3D also offers a library of full length downloadable 3D movies directly on their website, making it easy for their customers to build their own 3D movie collection.

The NAV3D6 Glasses Free 3D Digital Media Player is priced at $199, and the NAV3D8 and NAV3D8B are both priced at $299. The NAV3DCAM-10 is priced at $199, the NAV3DCAM-11 at $299, and the NAV3DCAM-12 at $399.

Stereoscopic Mammography Could Reduce Recall Rate
3D-News Posted: Wednesday, November 14, 2012 (8:47 UTC) | Posted By: Webmaster

A new three-dimensional (3D) digital mammography technique has the potential to significantly improve the accuracy of breast cancer screening, according to a study published in 'Radiology'.

Two-dimensional (2D) x-ray mammography, the current primary screening method for early detection of breast cancer in women, is a valuable tool but has some limitations. Surrounding normal tissue can mask lesions, and 2D views do not provide direct information about the volumetric appearance—meaning the three-dimensional physical shape—of a detected lesion.

A novel technique called stereoscopic digital mammography (SDM) addresses these limitations by mimicking the way that human eyes work together to form a 3D image. The technique uses digital mammography equipment that's been modified to allow the X-ray tube to move separately from the cassette. The resulting images are viewed on two monitors mounted one above the other.

"Our eyes see the world from two slightly different perspectives," said Carl J. D'Orsi, M.D., from the Department of Radiology and Imaging Sciences at Emory University School of Medicine and the Winship Cancer Institute at Emory University, both in Atlanta. "In this technique, the X-ray tube functions as the eyeball, with two different images providing slightly different views of the internal structure of the breast."

By using a unique workstation and polarizing lenses, SDM has the ability to identify lesions at different depths within the breast volume, potentially reducing both false positive findings and recalls while enabling more accurate diagnosis.

Dr. D'Orsi and colleagues recently compared SDM to 2D digital mammography in 779 patients at elevated risk of developing breast cancer because of personal or family history. Patients received both exams in a single visit, and two experienced radiologists independently interpreted the final total of 1,298 exams. Imaging findings were correlated with results of one-year follow up or biopsy.

SDM significantly improved the accuracy of cancer detection. The specificity of 91.2 percent was better than the 87.8 percent rate for 2D digital mammography; and the accuracy of 90.9 percent, compared with 87.4 percent for 2D digital mammography, was also a statistically significant improvement.

"We found that the stereoscopic technique could significantly decrease the need for calling women back for additional exams," Dr. D'Orsi said.

Dr. D'Orsi and colleagues are expanding their research to study SDM with a lower radiation dose in the general screening population. The radiation dose used in the study was approximately double the standard dose for mammography.

"In this study, we used a high-risk population to get an adequate number of cancers, and we acquired each of the images comprising the stereo pairs with a full standard X-ray dose," he said. "Now that we know the technique is worthwhile, we're repeating the study in the general population with a dose comparable to routine screening mammography."

Digital Signage Professionals can now Deliver 3D Presentations Quickly With the Latest Version of a 3D PowerPoint add-on
3D-News Posted: Monday, November 5, 2012 (9:43 UTC) | Posted By: Webmaster

Presente3D, a stereoscopic 3D add-on for Microsoft PowerPoint, announced that it released an updated version of its 3D presentation software. It can now be used in creating presentations for digital signage applications. In the latest version of Presente3D, it supports the creation of 3D slideshows through its integration into PowerPoint so that looping presentations can be made. Digital signage professionals can now start creating 3D presentations within minutes! No special requirement for hardware is necessary and it is available for a fraction of the cost of traditional 3D digital signage applications.

Support has been added for commonly used interlaced 3D for passive 3D displays which allow users to utilize less expensive 3D eyewear for viewing presentations. Digital Signage professionals also have the opportunity to display their 3D presentations on autostereo displays manufactured by Dimenco.

"Many of our customers have been using Presente3D for digital signage applications and with the latest release of Presente3D we have given them the support for easily creating presentations with software that they are using today." Alexei Chapko, Director of Business Development, Presente3D

New features of Presente3D v1.1 also include:

  • Slide show support for creating automatic looping presentations.
  • Ability to run a previously exported presentation without re-exporting the whole presentation
  • Interlaced stereo support now works with a variety of passive 3D displays and laptops
  • Various bug fixes and usability improvements
