equality tech 3d dental scanning review? dental scanning implants in MI?

Steve

Anyone in the dental field use equality tech for dental scanning? deep scanning area, sharp margin line etc.. how quick is their turn around time & final product? please answer only if your familiar with this technology, thanks.

Answer
I've actually purchased there DS2 white light scanner for our lab. We love it and its very automated with a click of a button it scans 18-23 areas. Very fast!!! The scanner has 2 cameras that allows it to scan deep areas and for sharp margin lines it has 2 high resoulution cameras and its an open system. Good Luck and I defiantly recommend them.

Can someone use this idea for cameras ? Please pass along and maybe it will evolve into something worthwhile !?

Mr. J

Dear Reader,

I offer these ideas for your consideration. First a few comments.
In the 1980âs a type of computer program, known as an expert system, was developed to diagnose Meningitis after reviewing the symptoms of possible candidate patients. It was more effective than the doctors it was tested against ! It is, I think, reasonable to assume that many other such programs could and should be developed and made widely available to the public. This would go a long way in reducing health care cost and move us forward technologically speaking, as a species. Now to, how this relates to camera improvements.

First: It is a fact that many human diseases reveal themselves in human fingernails, toenails, and in the eye. I am suggesting that a digital camera, loaded with a well written program, probably a combination of expert system and neural network could be used to diagnose potential disease conditions. Simply, place your hand or other such appendage on a controlled surface, take a picture and analyze same. I am aware that this concept is very general but I offer it to you with the hope that you will give it fair consideration.
If successful this could open up exciting new markets for camera makers.

Second: I would like to see a camera that has a program that will determine the area of surface by simple taking a picture of it. I think this should be fairly straight forward if you were to use Pickâs formula for determining area.

Third: I would like to see a digital camera add a long exposure feature to itsâ list of features. Once again I think this should be doable by creating a program that tells the camera to take pictures at intervals and âoverlaysâ each picture, thereby capturing more light for each picture pixel. Of course, a motorized tripod could be used to capture astronomical footage. This technique should increase still picture quality by orders of magnitude !

Lastly: The Intel corporation recently announced an optical device that will be available soon that will be fast enough, I have read, to download a high definition movie in on second ! This will of course make USB obsolete. It would seem that one could use this tool to connect a camera to other devices such as a microscope, telescope, or any other âopticalâ reader and get excellent video and extreme data analysis. I hope to soon see this available to the general public.

I have posted these thoughts on the web. I hope these memes evolve and inspire others to create.

Thank you,

Mr. J
Thanks for your input Joe.

On item 1, please realize that many corporations have a vested interest NOT to create such a program, whereas, camera makers are in need of ideas that will allow them to compete with ever better cell phone cameras.

On item 2, The area idea was meant to be a quick fix to problems like , finding the area of a wall you might want to wall paper or paint. It would only be used for "good enough approximations.

On item 3, I was thinking more about the possibility of using the camera via long exposure to act as a substitute telescope. Each image captured would bring new light to the lens. A program would add this photon info, by laying each image on TOP of the prior image. The internal program could keep track of new information being picked up thereby allowing a simple camera to view deep sky objects, and vivid still photos.

If no one else has input I will give you the best answer. I just wanted to post these ideas somewhere, in the hopes that by creating a mem

1 - interesting idea - however i think it would make more sense to create some computer software and then tether it to an off the shelf camera - reducing costs over all.

2 - To determine the surface area, you would have to have a 3d model of surface, because otherwise it would not be able to take into consideration and bumps or groves, as these would just appear as a flat surface. i believe that there are laser scanners that can already do this. I think they use them to scan in the 3d sculptures that are created to create animations such as the ones produced by pixar.

3 - There is a product that does it, and infact you can do it yourself, if you take hundred of pictured of a scene from the same point, load them into photoshop, and merge them, it will create a huge image that is all of yours stitched together to make one. Google Gigapixel photo.

4 - Light Peak - the technology you are referring to most probably will make usb obsolete. Telescopes are already available with mounts that allow you to place an SLR on the back, and use it as a huge lens. And video microscopes are available, with electron microscopes being able to produce very detailed and highly magnified images. The data transfer speed is not the issue here, rather the resolution of the cameras.

Anyway, some interesting ideas.

Joe
