[Anita Damelio]

3DISCis a privately-owned company with offices in the United States and France, as well as an R&D division located in Korea. Our dedicated team consists of digital experts from a wide range of high-tech fields, all working together towards a single goal to revolutionize the future of digital dentistry.

Our primary goal is to go beyond the conventional limits of digital technology by providing inclusive solutions that offer significant clinical advantages, with a particular focus on intraoral scanners.

We have conducted a study to assess the medical benefits of incorporating Scan&Tell into the dental practice with a specific focus on evaluating its impact on patient communication, engagement and the increase in the number accepted treatments.

"Scan and Tell has become an incredible means of communication between me and the patient. I utilize it for diagnosis, planning, and finalizing cases. It serves as a crucial strategy to convey information clearly and directly, ensuring the patient comprehends their oral situation and can adhere to the treatment plan"

"Scan&Tell has transformed my daily clinical visits. I consistently incorporate it in my initial appointments to visually assess and explain any dental issues directly to the patient, just as I observe them in the mouth. Patients highly value this form of communication, finding it easy to comprehend the diagnosis and willingly accepting the treatment plan."

"I find the software very easy to use and having the support of the team in Paris is a great asset, especially when the support gives me great clinical tricks and tips, which safe me time and money and deliver happier patients. My HeronIOS has paid for itself already, in only a few days. If anyone is 'teetering' on the edge of purchasing and wants to speak to me about my experiences using my HeronIOS, I would be happy to talk with anyone!"

"Scan & Tell helps me explain the necessity of certain treatments that may not seem necessary from the patient's perspective. It assists me in explaining the diagnostic process and helps building a relationship of commitment and trust with my patients."

Hard disk bad sector is the most common problem and the disk is not safe to store data any longer. The bad sectors will cause the important data loss and blue screen error sometimes, and even slow disk speed. Macrorit Disk Scanner is a third-party portable disk surface test and hard drive health diagnostic tool, which provides you better options and performance than Windows native disk scanner

With the fastest algorithm, this disk scanner free software usually could reach the maximum speed that supported by the device. It is compatible with all recent versions of Microsoft Windows - both client and server and supports major storage device types such as IDE, SATA HDD and SSD, SCSI, FireWire, hardware RAID, flash cards and more

Sometimes, you may notice, that some files on the disk cannot be read. This may happen for several reasons, but the most important one is the hard drive degradation, that may be the first typical sign of the disk failure.

Disk Scanner is able to scan any disk which you see in Windows. It can be a built in ATA or SSD hard drive or external USB hard disk, or a flash card from your digital camera or the smartphone. Just choose the drive letter, press button and the scanner will start examining every cluster on the disk.

It not only checks your disk for read errors. It carefully identifies and lists all affected files. At the end of the scan you will have the full list of files which located on the unreadable sectors, i.e. which contain unreadable parts.

Might be less effort to scan them on a flatbed scanner. There are quite a few that can scan negatives/slides at reasonable resolution and they're not very expensive. Won't be as good as a dedicated slide/negative scanner, but it will be a lot less work if you have a lot of disks

An easy approach with traditional photo skills would employ a bellows, enlarging or prime macro lens, copy stand and light box. I'd use slow Ektachrome (not Fuji) and duplicate the disc shots as enlarged "negatives." That would lose no sharpness at all (sharper than the film scanner). Might also shoot a roll OVEREXPOSED by 1 stop and pull-processed to reduce contrast.

...incidentally, I've done that bellows/macro/lightbox thing with all sorts of film originals, including 35mm internegs (common color neg film) from tiny Super 8 Ektachrome footage of famous athletes. Easy money. But there has been nothing worse than Kodak's Discs.

One of Kodak's original plans for Discs involved a scanner on top of your TV, viewing and adjusting on the TV, sening by slothful modem to a Kodak lab for printing and return via snail mail. I don't think many know about this. I saw the setup at the huge pro Las Vegas photo trade show in the Eighties, don't know if it actually worked.

Buy a roll of slide film. Shoot the whole roll at something very white and open up as many stops as you can. Develop this. You will now have a whole roll of tranparent film. Cut into sixes or fours (whichever your holder takes). Sandwich your negative between these two bits of plastic. That should hold them in place. Alternatively go to a craft shop and buy the clearest cleanest plastic film you can get and cut them to negative strip size.

We use an epson v750 pro with a laser cut carrier to register the film precisely each time. The entire disc is then scanned and the frames seperated out using photoshop actions (this where the precise placement of the film becomes necessary). This scanner allows a 6400 dpi scan which is plenty big for disc film and our lower priced scans are only 2400 dpi and they don't show any digital artifacting in a 4x5 print. Once scanned all frames are then digitally density and color corrected, degrained, sharpened and a small bit of spotting is done. Anyone can do it but whether it's worth the time and effort to do it well may depend on your patients.

Update...these scans are now done on a Creo iQsmart 3 at 5200 dpi but instead of the laser cut carrier we are now removing the films from the hubs so that they'll sit perfectly sandwiched in the scanner glass. It's not a huge jump in quality from the v750 but it is as good as you're going to get from these.

The proper way to do this if you want quality scans is to remove the paper from the plastic and scan the paper, not the jewel case. You can pry open the jewel case base to get the sleeve out, just be careful not to break the case.

If the sleeve is glued to the base... then there may be nothing you can really do about the blur. You might have better luck taking a good photograph of the base rather than trying to scan it. Flatbed scanners inherently don't work with depth well.

This disk scanner needs someexplanation. It uses a modified Unimorph disk. Unimorph disks areone of the most common piezoelectric devices available. They are most oftenused for small sound generators, speakers, buzzers. A Unimorph disk ismade of two disks bonded together, one is a piezoelectric ceramic the otheris metal. The metal disk makes it much less fragile than the ceramicalone.

The piezo ceramic expandsor contacts when an electric field is applied to the disk. A standardUnimorph disk bows up or down as a voltage is applied between the metaldisk and the silver electrode. The Unimorph disk used in this design movesabout 0.16 mm/Volt,and its natural resonance frequency is approximately 2.5 kHz.

As the voltage on opposingelectrodes are changed the angle at the center of the disk is changed.Because the voltage causes a change in angle the motion in the X-Y plainis directly proportional to the length of the standoff.

I recently decided to scan some old family negatives on Kodak discs, a format infamous for its poor quality, ridiculously small surface (and hence huge grain and poor details), difficult handling and a slew of other defects. Bad but enlightening idea.

I first tried to scan it with a standard 35mm slide scanner: big waste of time. You have to cut the disk in pieces to separate each frame, place them carefully with tweezers into the film holder, they are impossible to keep level and focus on properly unless you add a glass in the holder, etc...

Then I took the next easiest path, a flatbed scanner with a transparency back large enough to accommodate the disks at once such as the Epson Perfection V500 Photo, which works under Linux with a bit of tweaking. The idea would be to scan the entire disk at once and then process the individual frames in separate software with a workflow such as: Scanner -> 64RGBI scan -> Vuescan -> DNG file -> Raw processing program -> Multiple frames. Easier said than done. The main problem stems from the fact that a big part of the scan is completely white (the axle) while the other is completely black (around the disk). Also, since the images are so tiny, you need a high resolution but the resulting image is huge enough to crash most OS or scanning softwares if you use the best resolution your scanner can give (6400dpi in my case).
