Subject: [roots] Scanning x-rays
This is how to used to scan my X-rays...but since going OpTime I don't have to do any of it.
But for those who don't have Optinme or digital radiography this is a simple way to digitize your rads.
BTW, You don't have to use a wide angle lens, but since I had it I used it.
The wide angle lens was placed directly on the x-rays and eliminated camera shakes.
Place x-rays on the view box, turn the room's lights off (You can also use your darkroom) and take
a picture of the x-ray on illuminated viewbox.
Use the Macro feature ( Tulip icon ), turn flash off and set the camera to B&W colors. This will get
rid of bluish tint and adjusts the grey scales.
Focus on the x-ray and use zoom to eliminate the vignetting ( the dark circle around the image seen
through the camera's LCD screen or view finder) .
Shoot picture, take the card out , use any of the imaging programs ( ACDSee, Irfan View, Photoshop etc )
to manipulate the image if needed....then transfer images to a folder, your image organizer etc.
I use TDO program for instance, other programs can do the same thing.- ahmad
Ahmad’s technique is excellent. The only place I would differ is that in my hands, and when I have
discussed this with the “experts”, I get better results if the photo or scan if one uses a scanner,
is set at full color, and then in the processing through the various software one eliminates
the coloration issues by changing to grayscale. The theory is one gets all of the data that the camera
can provide that way. I have tried it both ways and in our office we do get better results that way - gary
What great tips Ahmad, for those of you like myself who have been on Roots since its inception ,
you will know how unselfish Ahmad is with sharing his clinical tips and showing his excellent dentistry.
Clap clap clap Ahmad......nicely laid out and it is a great way to digitize your radiographs.
Thanks for sharing - Glenn
I would like to know if wide angle is better than teleconverter for that work or not.
Thanks to you very much - Laura
