Evaluation of Physical Properties of Different Digital Intraoral Sensors

intraoral cmos sensors

For those interested in learning more about the differences in physical properties of different CMOS intraoral sensors, we published our findings in this scientific paper. You can find more information about the paper (free access) by following the link:

The sensors are: XDR (Cyber Medical Imaging, www.xdrradiology.com); RVG 6100 (Carestream Dental LLC [distributor of Kodak products in US], www.carestreamdental.com); Platinum® (DEXIS LLC, www.dexis.com); CDR Elite (Schick Technologies Inc., www.schickbysirona.com); ProSensor™ (Planmeca, www.planmecausa.com); EVA (ImageWorks, www.imageworkscorporation.com); XIOS Plus (Sirona, www.sirona.com); and GXS-700™ (Gendex Dental Systems, www.gendex.com).

Upcoming CBCT symposium

Casrestream Dental

Carestream Dental 3D Symposium: A great opportunity to learn much more about CBCT. On November 15 – 16th in Atlanta, GA Carestream Dental has twelve (12) leading experts lined up sharing interesting perspectives on CBCT.   To register and / or learn more, please go to: www.carestreamdental.com/3DSymposium

 

Attending the 3D Symposium will give you valuable insight to what’s new in the 3D digital world of dentistry, and knowledge that can bring more efficiency to your practice and earn 12 CE credits, too.

Installing DCM4CHEE 2.7.2 with MySQL and Weasis web viewer under Windows 7

When I first wrote the installation tutorial for dcm4chee for Windows 7, I didn’t quite expect the enthusiasm from the community. The feedback was very positive and I feel glad that I did the tutorial and helped many people get the installation done. 
It’s been 3 years since I wrote the tutorial and things have changed. Many started asking me to write a new tutorial to help them install the newest dcm4chee with the new “Weasis”. I’m delighted to let you know that this tutorial will walk you through the steps on how to install latest dcm4chee, as of this writing, and how to install Weasis and integrate it with it.
It took me several hours going through trial and error till I got it working. I hope you don’t have to go through that process. This tutorial assumes that you will install dcm4chee 2.7.2 using mysql database and Weasis web viewer under Windows 7 professional 64 bit. New versions on dcm4chee might work so try the newest version and see if that will work.
I appreciate all the positive comments and constructive feedback. So without further ado let’s jump to the installation!

How to get higher resolution radiographs in Dexis Platinum sensor

Dexis High Ultra High Feature

Dexis Platinum sensor offers practitioners two modes to capture radiographs: High resolution mode which captures radiographs at 0.5 mega pixels (846 x 662) and the ultra resolution which captures at 2.0 mega pixels (1692 x 1324). By default the software is setup to capture at 0.5 which limits the resolution of the sensor to about 12 lp/mm (line pairs per mm). Switching the settings to 2.0 mega pixels can give you higher resolution radiographs with approx.18 (lp/mm) resolution. This allows structures to appear crisp and overall easier visualization of structures when zooming. If you are doing endodontic work and you prefer to have better visualization of the tip of your endodontic file then the higher resolution will give you better radiographs. Other diagnostic procedures might benefit as well. Continue reading

Exporting from Maya to iBooks Author

In this video tutorial we’ll see the steps on how to export a 3D model from Maya to display it inside a book on the iPad. Getting the exporter model to work was a bit tricky but it finally did.

We used a DentSply XCP ORA film holder as an example to demonstrate poly counts, textures, and light setup as part of the upcoming oral radiology interactive textbook for the iPad. Feel free to drop us a comment or share the video with your friends.

 

X-Ray Phase Contrast Radiography and CT

Presented by Franz Pfeiffer, Technical University Munich, Germany. ECDMFR 2012
The presentation reviewed development of phase contrast radiography and shows the difference from conventional radiography. Very interesting research for clinical application in medical imaging.

Apple Ed Seminar presentation is now available

iOS apps in dentistry

I demoed some of the work we did for Apple iOS devices like the apps and the new iBook project. The event was successful and Apple folks liked the presentation. We look forward to bring the Oral Radiology iBook to students. No ETA yet but we got great people on board who will be helping out make the project a success. For now you can hit the link to watch the video. Thanks to everyone who helped with that!

Apple Education Seminar at the University of Michigan – We will be there!

Apple will be hosting an education seminar at the University of Michigan in Ann Arbor. You are invited to attend a session focused on demonstrating how technology and mobile devices like the iPhone, iPad and iPod touch are impacting the classroom, hospitals and clinics.
We will be there presenting our iPhone apps and showing the new iBook project for teaching oral radiology. The presentation will be at 10:45am  ” Do you have an app idea”?
Apps in use and developement at UM
We look forward to see you there

Oral Radiology iBook proof of concept video

oral radiology ibook ipad proof of concept

We have been experimenting with Apple iBook Author, a software that lets authors publish highly interactive iBooks on the iPad, we were able to see how this technology can be a game changer for learning and teaching.

The video is a proof of concept of how the final book will use some of Apple technology to innovate in oral radiology education. Video after the break.  Continue reading
