In our previous tutorial, we demonstrated how to install and configure dcm4che as a PACS server. In this tutorial we will go over how to make dcm4che accessible through the internet.
Depending on your network configuration you might need to modify things here and there but the principles are the same. Again Google is your best friend.
This is the presentation entitled: “Developing next generation oral radiology iPhone and iPad apps for current generation students” that I gave on 11/19 at the AAOMR 2010 meeting in San Diego, California, USA. The video shows the tools we used to create the Cone Beam CT app and the panoramic app on the iPhone. There is a demo for both apps running and this is the first time we demo the videos live.
I would like to thank the companies who helped support the apps (listed in chronological order): Imaging Sciences, Kodak, Planmeca, Soredex, and Sirona.
We are committed to bring you new cool oral radiology educational tools on mobile platforms. If you would like to translate the app in your language send us an email and we will include your name on the app.
Feel free to drop us a comment.

During the AAOMR 2010 meeting in San Diego, I had the chance to sit down and talk with Kathy Kincade, Editor in Chief of DrBicuspid website. Drbicuspid.com is is a free, member-driven Web site dedicated to general dentists, specialists, and other dental professionals.
I went over the things we have been doing and the recent development of mobile apps to teach oral radiology, what has been accomplished and where we are heading.

An interesting article published today by The New York Times citing usage of Cone Beam CT especially by orthodontists and the worries for radiation risks for children who are more susceptible to radiation.
The article also goes over “lazy” dentists who still prefer to use D-Speed film over F-Speed mistakenly thinking it is superior at the expense of 60% more radiation. This however seems to affect the US more than other parts of the world.
Be prepared for a lengthy article. Follow the link for full article
The new version of the iPanoramic app has seen the light of the day. We have been working hard in the past two weeks and it is finally here. Launched during the AAOMR 2010 meeting, the new version (1.2) comes bundled with new features:
Portuguese translation is courtesy of Dr. Luciana M.P.S. Ramos Fernandes, (DDS, MSc, Dental radiologist, Bauru Dental School, USP), Sao Paulo, Brazil
Spanish translation is courtesy of Dr. Ronald Ordinola Zapata (DDS, MSc, PhD student, Bauru Dental School), Bauru, São Paulo, Brasil
Translation for other languages is still needed. If you think you can help please let us know and we will follow up on that. Translators get the app for free and their name mentioned.
The app can be downloaded by going Here
Finally, it is here. The first app to teach dental panoramic radiographs! 
Panoramic radiographs provide a general overview for the patient’s teeth, bone, and jaws. A panoramic radiograph is usually used to detect and assess impacted 3rd molars, pathology, or in patients who are partially or fully edentulous. Continue reading
Please join us at a comprehensive presentation for general practitioners. We will cover the basics of 3D imaging and how it is fast becoming a critical tool for success in the dental practice. Learn how to use the technology, for example, when a specialist sends you the disc of your patient for orthodontic treatment, for periodontal treatment or for oral surgery procedures.
To get familiar with the technology, participants will conduct hands-on demonstrations on multiple computers set up to demonstrate cone beam technology. A computerized surgical template will be shown placing an implant in a live surgery demonstration.

It is this time of the year again. The 61th AAOMR annual meeting will be held in Kona Kai resort in San Diego, California and guess what!? We’ll be there!
Time: 9:10 AM Thursday Nov. 18th 2010
Location: Loma Linda room
This November I’ll be presenting the latest development of the iPhone apps for oral radiology. The title of the presentation is: “Developing next generation oral radiology iPhone and iPad apps for current generation students”.
The phone has evolved to become a handheld computer. This small device now allows you to access the internet, record videos and pictures, and run small programs called apps. It support multi-touch and interactive features.
I have 70 students in the class I teach. When I asked the students: how many of you have an iPhone or iPod Touch; about half of the class raised their hands. I showed them the CBCT anatomy app and the students were very excited to get it on their devices. To me this sounds like: I want to get it and use it… rather than me keep telling them to read their assignments from the textbook which I think not many of them do.
Let’s face it. Time has changed and current generation students these days prefer to be surfing the internet, or check Facebook, or spend more time with their computers/phones than ever. It is faster to search in Google or Wikipedia than looking something up on a book. We need new forms of education that take into consideration our students needs.
Forcing older methods of teaching in my opinion does not work like it used before if at all. Students don’t have the time to spend reading large pieces of text and they prefer to read the powerpoint presentation instead. So how do we tackle this problem? Continue reading
We’re pleased to announce the App Store Volume Purchase Program. Education institutions in the United States now have a new way to purchase iPhone apps in volume for distribution to their students and faculty.
The special pricing offer will be 50% of the listed price to education institutions when they purchase 20 or more copies of the same app. Marcilan will apply this special pricing to all of the current and future applications.
Current Cone Beam CT reconstruction algorithms use the processor (CPU) to process the acquired data to generate an image. Graphics processors like NVIDIA Tesla can also process data but at 10-100 times faster than computer processors; however, programming for graphics processors is much harder and only recently it was made possible thanks to technologies from NVIDIA to help programmers do that.
Researchers from the University of California at San Diego were able reduce the amount of radiation to patients by ten folds or more thanks to a new approach for processing x-rays.
Cone Beam CT is not only used for scanning patients but also is used in image-guided radiation therapy (IGRP). Reducing total number of projections, mAs level per projection during a CT scan reduces the total radiation dose delivered to the patient. However, this results often in a noisy and mathematically incomplete data that takes hours to process through iterative processing via the computer’s processor. Because the Cone Beam is used for treatment, fast reconstruction is needed, explains the lead author Xun Jia, who is a post doctoral fellow at UCSD. Continue reading
